July Hits (2014)

- July Hits -1) Have you heard about using isometrics to decrease pain associated with tendinopathies?  I was unfamiliar with this concept so I thought I'd send out a tweet to one of the leading experts, Jill Cook.  She gave some great advice that you can immediately use in your practice.  Jill's guidelines:

• Joint Angle = Inner Range Holds

• Duration = Long Holds (up to 45 sec)

• Intensity = Heavy as Possible (no perturbation)

• Frequency = 2-3x/day

• Keep in mind it will vary for each person

2) A great article summarizing how to improve Crossfit training.  It's really just a good article on programming and layering movements (not just for Crossfitters).3) The Schroth Method seems to be gaining some popularity.  I've even had a couple patients ask me about it.  It looks like it has very similar methods to the Postural Restoration Institute (PRI).  #Scoliosis4) Great read on diet and the human microbiome from Eirik Garnas.5) Adriaan Louw is my favorite pain science guy.  Here are 3 articles with some great Adriaanisms: Zac Cupples Course Review, 11 Questions with Louw, Therapeutic Neuroscience Education6) Ever wonder about that focal loss of hair on your patients legs?  Gait Guys explain it here.  "Hair growth is influenced by local blood flow and “tropic” influences from the autonomic nervous system and sensory feedback loops, supplied to the area segmentally (ie. by each spinal level). "7) The hip hinge is one of my favorite exercises for both myself and my patients.  Seth Oberst goes over it nicely in this post.  Great cue - "Giving at the knees, taking at the hips."8) Sleep for improved motor patterns - "Neurons that fired during learning fired again during subsequent slow-wave sleep"9) Isometrics decrease the blood supply to the muscle, thus making it a great anaerobic exercise.  From a neuro perspective, it increases the neural drive.  These two benefits alone make it worthwhile for your training program or your patients rehab.10) In rehab and fitness, the pendulum eventually swings the other way.  Kathy Dooley explains how the popular knees out cue can be the wrong cue for your patient.  Don't sacrifice tripod foot for proximal alignment.11) The unathletic population can sometimes have difficulty performing MDT shoulder resets.  Here are 3 variations to help troubleshoot this problem.12) 3 Factors for Skill Development from GMB: Adaptability, Prioritization and Cycling, Mindful Practice13) "A big grip tells the brain that the position is a stable one and it is safe to generate a lot more force without risk of destabilization and injury."  Great post from Seth on the importance of grip strength and the nervou system.  Here's another article on grip strength I wrote a couple months ago for Physiospot.14) Tom Myers has a great answer to a question on fascial lengthening direction.  "Since what we want to do in a locked-short muscle is break / melt the bonds between these angled fibers to allow the myofascial unit to lengthen, we run along the tissue in the same direction as the muscle fibers, presumably unwinding some of the muscle tension, presumably hitting some trigger points along the way, but absolutely melting the hydrogen bonds that run in that direction and keep the tissue from lengthening."15) I've really enjoyed Sue Falsone's blog so far.  She's got a great perspective.  Here's one on the different approaches she uses - "How do we blend concepts without “drinking the Kool-Aid” of any one philosophy or teaching?"16) Chris Johnson introduced me to the power of expectations and placebo with this article.  It's important to be aware of this aspect of treatment and to know how to use it to improve outcomes.  Here's another article on the placebo effect and how it can be a good thing.17) "It doesn’t matter how much force you can generate with your extremities if your trunk is not strong enough to oppose and transmit it; and it doesn’t matter how rigid you can make your core if the contraction is not timed properly based on the specific movement demand."  Nice article on half-kneeling from Quinn Henoch.18) Foundational Strength Course Review - The first FMS/StrongFirst course taught by Gray Cook & Brett Jones19) "Any time we make a rapid change, that change is neurophysiologic, not mechanical" -Erson Religioso20) I created this image to simplify the forces associated with the deep squat.  It seemed to get a lot of attention on twitter this month.21) "We should recognize that in some cases, one of the quickest and easiest ways to change motor control is to change the structure of the body which we are trying to control." -Todd Hargrove on how structure affects function.  Great example using the stepping behavior during infant development.22) "Hip socket depth, which is an anatomical variant that can’t be stretched, trained, or undone without surgery, is one of the main biomechanical influencers in how low you can go into a squat before you essentially run out of range of motion and have to find it elsewhere"  Great article on hip joint morphology and it's association with the deep squat by Dean Somerset.23) Mike Robertson has the most thorough exercise tutorials.  Here's his new one on the push-up (and variations).24) “Neutrality is not a point on a map. It’s a parasympathetic state of being.”  - James Anderson (via Zac Cupples)25) David Butler has been stirring the pot lately.  He wrote a post on cancer and whiplash here.  Then Alan Taylor wrote a rebuttal.  It's kind of an angry response, but he has some good points.  Overall I think we should spend less time trying to nullify other approaches and more time trying to share positive knowledge to improve our patient care.26) 3 Reasons Why You Should Focus on Breathing27) Why kids fidget, the ADHD problem, the cause, and a solution - a must read for the future of our species.  “In order for children to learn, they need to be able to pay attention. In order to pay attention, we need to let them move.”28) Great interview with the Seahawks PT, Michael Tankovich.  Some gems: "Movement screening is a daily process.", "The basic premise is that throughout the rehabilitation process, the tension levels applied to the injury site must progressively increase until they reach competition level intensity.", "The first step to improving recovery is to develop a culture of knowledge."29) Are broken bones stronger after they heal?  Answer is here.30) Tommy John surgery has been getting a ton of publicity this year.  Chris Butler put together a nice collection of articles to catch up on why.31) People You Should Know - Vladimir Janda is one of the most influential movement specialists of all time.  However, he is much more than simply the guy that founded the Upper & Lower Crossed Syndrome.  "He was one of the first physicians to combine therapy and medicine in a ‘hands-on’ approach, becoming one of the earliest to practice physical medicine and rehabilitation."  In a time where everyone was focused on isolated strengthening and passive joint structures, Janda developed "Sensorimotor Training" and focused on balance and function.32) Top 3 Tweets of the Month

Foundational Strength Course Review

Two of my favorite things to do in my practice are to assess movement patterns and use kettlebells.  So when I heard about the amalgamation of FMS and StrongFirst I was pretty stoked.  Throw on top that Gray Cook and Brett Jones were teaching the course, and it was my most anticipated course of all time.Foundational Strength - June 20-22, 2014

Gray & Brett

Gray Cook has been the biggest outside influence on my career.  After graduating from PT school and practicing impairment based PT, I started to notice that there was something missing.  Gray Cook and the SFMA/FMS filled the void.  I've watched almost all the DVDs, read the books, and have attended the SFMA courses.  I was excited to finally catch him live in action.  And he didn’t disappoint.  The man is extremely entertaining, engages you with every word, somehow talks in quotes, and delivers complex and deep concepts in a country simple manner.  And if you can catch him during the breaks he’d blow your mind.  Plus, it’s great to see his passion for movement.  He’s not trying to make money, put down other approaches, or spread a dogma; he’s just trying to help humans “move well, move often”.The surprise for me was Brett Jones.  I’ve heard him in a couple podcast interviews and youtube videos, but I didn’t know what to expect in a course.  I was pretty blown away with his expertise and perspective.  He is an extremely knowledgeable, humble, and humorous speaker.  But my favorite part about Jones was the practicality of his knowledge.   Many times I feel like instructors live in the fantasy black and white world where all their patients do everything they say and get 100% better.  The information and clinical pearls from Jones were extremely applicable and realistic.  Listening to and talking to Jones was like talking to the smartest co-worker you’ve ever had.Together, Brett Jones and Gray Cook were outstanding.  After both of them speak on a topic, there aren't many questions left to answer.

The Course

The course had 1 lecture to start on the FMS and a Gray Cook bonus lecture at the end.  The rest of the 3 days were packed with clinical pearls on screening, interpretation, corrective strategies, technique, programming, and kettlebells.  The amount I learned that can immediately go into practice is overwhelming.  I cannot recommend this course enough for anyone that is interested in movement.There’s no way to possibly go over all these clinical pearls in a blog post, but I'll try to highlight some of the great stuff I learned.

46 Things I Learned at Foundational Strength

1) “The best way to get motor control is through compression or distraction” - Gray Cook2) "Motor Control is Alignment, with Integrity, Under Load" - Gray Cook3) Quotes 1 & 2 explain the rationale behind most of the exercises we learned in this course4) I need to redo all of my FMS screens; I was way too lax.

One of the assistants said it best - "A 3 should look oddly graceful"

5) The set-up for the Screen is the most important.  Spend time getting the proper start position and alignment.  Be brutally detailed.6) “If your screen is wrong, your correctives are wrong”-Brett Jones7) 3's are not the goal of the FMS.  Symmetrical 2's are good enough to train without any restrictions.8) Consider the entire screen when choosing where to start with correctives.  For example, someone with 1's on ASLR and a 1 on TSPU likely has a motor control deficit that prevents >2's on the ASLR.9) Mobility First.  Asymmetrical mobility (ASLR & SM) is the priority since it is the area that can make the most impact on all the other functional movements.  For example, if it's a 2/3 asymmetry on the SM and there's a 1 on the deep squat, you should address the SM.10) Need mobility to get alignment, need alignment to get motor control11) Corrective Progression

Screen/ID Corrective Pattern→ Mobility→ Static Control→ Dynamic Control→ Performance/Strength

Mobility (ASLR/SM) → Motor Control (RS/TSPU) → Functional Patterning (IL/HS/DS)

Half Push-Up12) The #1 priority of a corrective is to magnify what you saw in the screen, if it doesn't, then you're probably doing the wrong corrective13) “Corrective exercise is shaking the etch-a-sketch” - Brett Jones

Gives a window of opportunity to change movement

14) “Movement needs to be one of the vital signs, or we won't take movement vitally” - Gray Cook15) “Level the pelvis (ASLR), open the t-spine (SM)” - Gray Cook16) Foot position dictates the hips, the hips dictate the core17) Loaded Carry (Farmer's Walk)

Diagnostic = 3/4 of body weight, measure distance

Encourages alignment, increases integrity, improves work capacity, fires stabilizers

Cook Drill - Overhead⇒Rack Position⇒Suitcase⇒Opposite Arm Overhead⇒Rack⇒Suitcase

Cues - Stay Tall, Push Bell Towards Ground, Breathe

Safe exercise for almost everyone

18) Removing negatives (exacerbating behaviors, activities, exercises, etc.) is just as important as adding correctives.  They advocate removing the negative activities for 2 weeks.19) Gray Cook loves the Jump Rope

"1 minute of jump rope = 2 minutes of running"

“Jump rope is more alignment oriented than running”

20) If a corrective is not changing the movement, then move on.  Don't waste time on correctives that don't lead to a positive change in movement patterns.21) I've never seen anyone so violently attack their neck with a Tiger Tail like Gray Cook does.22) Work the beginning and the end of a movement; the brain will figure out the middle23) Let patients feel the wrong position, exaggerate the extremes of the wrong alignment and then have them find the middleForward Lunge with RNT24) Core Engagement for Correctives

Needs to be reflexive, not a hard brace before the movement

Using arms - only pull band down to 40 degrees shoulder flexion, not to full neutral

Reset after each rep - if you engage the core and then do a bunch of reps, the brain still thinks it's one rep

25) Half Kneeling

Keep the front foot light, should be able to lift it without requiring a posterior weight shift

Tell patients they should be able to be stepping on grapes without squishing them

Spend more time setting up the pelvis in the correct 3-D position

Front leg should be 90º or more.  If less, the hamstring will try to help out too much

26) Brett Jones tells his clients, “your success depends on your ability to do your homework”27) “Every concussion is a whiplash” - Gray Cook28) Any asymmetry puts you in the “red”.  In other words, if you have asymmetries there are some exercises that will harm you.Tactile cueing for proper shoulder position during the trunk stability rotation.29) “Vertical tibia is a good intention, but a bad reality” - Brett Jones30) “Deadlift is not a pull, it’s a push.” - Brett Jones31) Single Leg Deadlift - set them up to reach and touch the wall, better sensory environment, patients feel safer32) Brett Jones knows as many movie quotes as he does FMS correctives33) C-Spine is the "fuse box" for the shoulders.  Many shoulder problems are really c-spine problems.34) Turkish Get-Up - don't high bridge from hand, high bridge from elbow and perform a low sweep35) Half Kneeling Windmill Exercise - more of a spiral than a shift36) Rolling

People got a little carried away with this exercise and started applying it to people that don't need it

It has a very narrow application

Most people don't have the appropriate mobility to be rolling

Don't over complicate it - you simply want the half that's moving to cross midline before the "paralyzed" half crosses midline

Use eyes and head for UE patterns

Prone to supine UE pattern - have arm abducted to 90º

Does 2 things: 1) Resets system with eyes, neck, and crossing midline 2) Promotes segmental movement

Jason Kapnick teaches it as a "reaching" exercise

Crooked ArmBar37) Kneeling exercises - want prime movers off.  If you lock in with prime movers, you lose reflexive stabilization.38) “if you get 2 inches at the hip, you get 1 inch at the ankle” - Gray Cook39) Only coach lifts and techniques, don’t tell people how to move.  You want people to feel movement, not hear it.40) Pigeon pose or hip ER stretches - keep knee in line with hip socket41) OTIS & ITIS (Oscillating Technique for Isometric Stabilization & Impulse Technique for Isometric Stabilization)42) Losing mobility = losing inputs = losing information43) There are 31-32 muscles that assist in hip flexion.  Don't assume or guess.  Don't isolate one muscle.44) “When you open your mouth, you blow out too much CO2 at rest.” - Brett Jones45) Balance should be achieved with rotation, not lateral movement.  This is why walking is so graceful.46) Sidelying thoracic mobility exercises (open book) - make sure they are not just "falling" into extensionOTIS for Ankle Motor Control

Bottom Line

This was one of the best courses I've ever attended.  Part of what made this course so great, was the required level of understanding prior to participating.  Everyone in the course already knew the concepts and theory.  So most of the time was spent on how to apply the right technique to the right patient and layer interventions.  I'm not sure I've ever walked into the clinic on a Monday after a course with so many new tricks to try.As with all interventions, nothing is a better teacher than kinesthetics.  Try some of these exercises on your own, then apply them to the appropriate patient.

June Hits (2014)

- June Hits -1) "When an imparted load exceeds the load bearing capacity of the tissue accepting it, damage occurs. Neurological errors in movement execution commonly lead to loads being placed on “unprepared” tissues. It is therefore important to focus on two aspects of training to reduce the likelihood of sustaining injuries: 1. Working on improving neural control via progressively complex movement tasks –  2.Improve the physical, mechanical load bearing capacity of tissues." - Andreo Spina2) Some good PRI exercises in this article by CPG.3) A story about a man amputating his own arm to try to get rid of his pain.  It didn't work.  #PainScience4) Avoid negativity, ignore trolls, stay open minded, and smile more.  "Smiling leads to decrease in the stress-induced hormones that negatively affect your physical and mental health."5) Mike Robertson has a great post on the importance of Force Absorption.  "Lee Taft likes to use the term “load to explode.” If you can't flex, adduct and internally rotate, you can’t effectively load your system."6) This is a great read from Sue Falsone.  We often spend so much time bickering about today's different approaches that we forget about our profession's past.  "There are no truly unique concepts at this point. Everything has its basis in history. What we are doing is refining, repackaging, recreating, and resurrecting concepts that have been around for more than a century, and using our modern knowledge and technological advancements to elevate these concepts to a new level."7) Here's a nice quick article on 9 Things You Should Know About Pain.8) Great post from Erson on Rapid vs. Slow Responders.  Tons of clinical pearls in this one.9) Having trouble with ankle dorsiflexion ROM?  Following a 6 week proprioceptive neuromuscular facilitation stretching program, ankle dorsiflexion was increased and tendon stiffness decreased.10) This is a great read from Cressey on mobility vs stability, squatting, olympic lifting shoes, and training vs. working out.  I couldn't agree more that we over-diagnose ankle restrictions.  Elevating someone's heels during the squat doesn't just take out the ankle mobility problem.  There's much more going on.  Assuming it's an ankle restriction is one of most common blunders in movement therapy.11) Another great way to feel awkward from the GMB guys - Crow Pose.  "Hand balancing is a great, enjoyable way to improve your upper body strength, whole body coordination, and awareness."12) Blood Flow Restriction Training is being used for performance, but should we start using it for rehab too?  Here are two evidence based articles on BFRT (12).13) "If sensitization of the central nervous system is in some part responsible for the persistent chronic pain complaints experienced by these patients, then treatment strategies should perhaps focus on trying to “desensitize” the central nervous system and improving endogenous pain modulation." -  Jessica Van Oosterwijck goes over pain education and it's effect on descending facilitatory pathways (endogenous pain modulation)14) The good, the bad, and the not so ugly Deep Squat - why it's good, who should do it, who shouldn't, and other important considerations.15) Is this a visual representation of what happens with manual therapy?16) Learn about Heart Rate Variability (HRV) - HereHere, & Here17) PRI has a truly integrative approach.  I learned about this when I was in the Postural Restoration class and Michael Cantrell had me bite a pen on my left side, take a few good breaths, and then my R shoulder IR improved 40+ degrees.  It's the most "magic" I've ever experienced in this field.  Lance Goyke shows you an entry point into the rabbit hole in this article on feet and teeth.18) Crawling seems to be popular these days.  And for good reason, but don't forget about the Turkish Get-Ups.  The benefits of each exercise are described in this article.19) When Gray Cook talks, I listen.  "Strength is the single best way to hit ‘save’ on a good movement document."20) Chris Johnson shows you how to take your single leg work up a notch.  Adding a barbell increases the stability/motor control demands, especially in the frontal plane (think see-saw and the fulcrum is your leg).  Try adding these for advanced patients - Barbell Marching, Barbell Step-Up.21) Stumbled upon the top 5 things Anthony Donskov learned in 2013: more specific adaptation, hypothalamus regulator, fatigue is more than muscles getting tired, best course/books, & pulse.22) Sometimes Short Foot exercises and dissociative foot intrinsic exercises can be too cerebral for some patients.  When this is the case, I go to Vele's Lean.  It's simply placing the foot in a neutral state, then loading it to activate the muscles in the correct position.23) Great TEDtalk - Kelly McGonigal: How to Make Stress Your Friend  -  "We know for certain, is that chasing meaning is better for your health than trying to avoid discomfort."24) Quick Book Review: The Polyvagal Theory by Stephen Porges.

Pro's: Gives you a better understanding of the Autonomic Nervous System and how the body progressively responds to stress; 1) Remove Myelinated Vagal (NA) Break 2) Activate Sympathetic Nervous System 3) Activate Reptilian Unmyelinated Vagal Nerve (DN).

Cons: More educational than clinical; doesn't offer many interventions.  The book is very redundant.  I felt like the book could have been half as long.

25) One of the biggest faults I see with the overhead press is loss of core stability and hyperextension of the spine.  Brandon Hetzler writes a great article on how to avoid this compensation and improve your press.  "Pressing from a standing plank is the ideal press posture, but how does one transfer a plank to a pressing, standing plank? My solution — the Press Plank."26) NOI Neuroscience Nugget - "Your muscles are dry."  A great metaphor to improve patient communication.27) People You Should Know - James Cyriax is considered the father of orthopedic medicine.  He was among the first to realize that imaging wasn't enough for a diagnosis and surgery wasn't always the best intervention.  So he developed an assessment to identify soft tissue lesions using passive and active movements; and he developed non-surgical intervention techniques that resolve the findings from the assessment.28) Top 3 Tweets of the Month

The Deep Squat (Part 1 - The Good, The Bad, & The Not So Ugly)

The deep squat (aka full squat, aka ass to grass/ATG squat) is one of the most debated, talked about exercises/assessment we have in human movement.  Some talk about the deep squat as if it's the cure to cancer, some talk about it like it's going to cause the apocalypse.  I have found that I always get mixed information and many take either a full medical approach, a full evolutionary approach, or a full performance approach.My goal here is to provide a blend of these approaches.  As a PT that loves S&C and evolutionary medicine, I hope I can give some evidence, some reasoning, and some clinical judgement on the deep squat as an exercise.Anatoly Pisarenko displaying the definition of the deep squatLet me again emphasize this is through the lens of the deep squat as an exercise; the squat as an assessment is a whole different story (PRI, FMS, SFMA, Loaded, ADL, etc.).If you want to stop reading here, please consider the conventional wisdom of great S&C coaches:

  • Squatting is not bad for you, the way you squat is bad for you

Disclaimer

I think a big part of the discrepancy with the performance with the deep squat is that there are so many variables associated with this movement pattern.  These variables include local physical impairments, movement history, exercise history, injury history, education, neuroception, structural changes, coaching, motivation, and culture.So if you took 100 people off the street and had them deep squat, you would see a smorgasbord of different movement patterns.This surfeit of human variables leads to a problem when trying to generalize one of the world's most complex exercises, let alone trying to create a study.But this abundance of variables isn't the only problems with the studies.

3 Reasons Why Evidence isn't the Gold Standard for the Deep Squat

  1. The populations vary from individuals who are young and have experience with the deep squat, to older individuals with possibly no experience with the deep squat.
  2. The studies don't seem to take into consideration any of the physical impairments; someone with an ankle dorsiflexion restriction is going to squat much differently than someone with a ankle motor control problem.
  3. The definition of the deep squat is completely different in some papers (some have mentioned parallel femurs as a deep squat).

So you can't expect too much from PubMed due to the inconsistent populations, lack of data on physical inputs, and a poorly defined task. Same logic applies to the squat:

Defining the Deep Squat

I'm going to call the deep squat simply a squat below parallel with a neutral spine.If you can't get below parallel with a neutral spine, you can't do a deep squat as an exercise.Getting below parallel with spine flexion is great if it's unloaded (SFMA, PRI), but in this article I'm focusing on the act of loading the deep squat for strength, performance, & movement enhancement.

We Used to Always Squat

Tired of standing? Squat down.Need to check something out or inspect an object? Squat down.Hanging out, shooting the shit around a camp fire? Squat down.This was the life for our ancestors (and for some of our current species in different cultures).It's Phylogenetics, the evolutionary history of our species.  It's our species' "family tree" from the beginning of time.The way our bodies have evolved over time has resulted in the movement pattern of the deep squat.Culture - the reason why most people can't squat like our ancestorsBut it's also Ontogenetics, the developmental history of an individual.  It's how the interaction of genetics, developmental programming, and environment affects the physical form throughout a lifespan.I've mentioned in a previous post that we have culturally evolved at a rate that far surpases our physical evolution.  Meaning, the world we live in is not made for our physical structures (chairs, shoes, school/work, technology, etc.).This mismatch means that the person in front of you trying to squat should be able to squat (phylogenetics), but may not be able to because of the way they have interacted with their environment (ontogenetics).For example, think of how a 4 year old can deep squat with no problem (phylogenetics), but the 50 year old, life-long sedentary, American desk jockey that can't flex his hip past 90 degrees because of structural changes in his femur/acetabulum has no chance at a deep squat (ontogenetics).But before you start analyzing your patient's phenotype, you should first understand the benefits, risks, and drawbacks of the deep squat exercise.

A Visual Approach to Squatting

Before discussing the benefits and potential drawbacks of the deep squat, it's best to understand exactly what is happening at the knee joint through varying degrees of knee flexion.Here's a diagram with the degrees of knee flexion and the associated forces/EMG activity.This is based on several studies, listed below.Squat forces and muscle activity * Most studies don't mention any activity beyond 135 degrees.  So this is unknown and why there is nothing beyond 135** It seems the force shifts from anterior to posterior between 50-60 degrees.  This is why there is an overlap.  Yes, I know it's impossible to have both anterior and posterior shear forces at the same time.

Why it's Good

It cures cancer!But seriously, the deep squat exercise has a ton of benefits (see chart below).In general, the deeper the squat, the greater the quad and glute activation.Plus, the deep squat spares the knee of shear forces and prevents ligamentous strain (see figure above).  Since most lower extremity injuries involve weakness and aberrant shear forces, the deep squat can provide a great exercise to help reduce injury.From a performance perspective, the deep squat provides a great exercise for increasing strength (legs, thighs, hips, core) and improving vertical (y-axis) movement efficiency.If you can deep squat without compensations you will reap many benefits

Why it's Bad

Ontogeny

The bad often comes from ontogeny.  Everyone was able to squat as toddlers, but what they've done since then will influence what they can do now.  In other words, the way someone has chosen to live their life may make the deep squat a bad exercise for them.  Everyone was born to squat, but not everyone has grown to squat.  This is due to the body adapting to life's imposed demands (mechanotransduction, Wolffe's Law, Davis's Law, bioplasticity, etc.).  Think of it as a structural SAID principle.Someone that spends their life in an anterior pelvic tilt, wearing high heels, and sitting for 80 hours a week will have structural changes in their ankles, hips, and lumbo-pelvic area that will prevent them from a deep squat.  This person would need years of specific training in attempt to reverse some of these adaptations to allow them to squat without compensations.

Compressive Forces

Another potential danger is the high compressive forces (tibiofemoral & patellofemoral) with a deep squat.  Since there is an inverse relationship between shear and compression forces, the benefit of less shear is at a cost of more compression.  For most, this isn't a big problem if you apply the SAID principle and progress slowly.  But for some it may be an issue.

Mobility Restrictions

In general, you should avoid prescribing the squat with people who do not have optimal mobility in their ankle, knee, and hip.  Simply stated, if you do not have adequate mobility in these joints you will compensate and cause more harm than good.

Pathologies

Getting more specific and research-based, I would be very careful to squat with people who have: meniscus pathology, PCL pathology, hip impingement pathology (labral tear or bone spur), chondromalacia (depending on location of pathology), or advanced symptomatic osteoarthritis.However, you should always treat the patient, not the script/image/anatomy.

But What About...

Many times in medicine, one of the first studies that come out on a subject becomes the most popular and becomes dogmatic.  This happened with the 1961 research article by Klien.  Klien reported that squatting was dangerous and increased laxity in the knee.  Everyone jumped on the anti-deep squat bandwagon back then, and some are still dogmatically against the deep squat; even though Klien's results have been refuted in many research articles since.Here are some questions that many have about the squat and it's safety.

Isn't it Bad for Ligaments?

"Because the squat generated lower ACL strain compared with walking or jogging, it was concluded that the squat was a low risk exercise in rehabilitation of the ACL". - Henning et al.

"In conclusion, basketball players and distance runners experienced a transient increase in anterior and posterior laxity during exercise. Power lifters doing squats did not demonstrate a significant change in laxity." -Steiner et al

Isn't it Bad for the Tissues Around the Knee?

"With increasing flexion, the wrapping effect contributes to an enhanced load distribution and enhanced force transfer with lower retropatellar compressive forces...Contrary to commonly voiced concern, deep squats do not contribute increased risk of injury to passive tissues." -Hartman et al.

Isn't it Bad for the Knee Cap?

This is basic physics (Force = Pressure x Area).  There is increased compression with the deep squat, but there is also increased retro-patellofemoral contact area.  Meaning the direct pressure on the knee cap is dispersed among a greater area, thus less focal retro-patellar forces.  Just keep in mind the location of the retro-patella forces associated with the different degrees of knee flexion.

Isn't it Bad for Knees?

"The squat does not compromise knee stability, and can enhance stability if performed correctly. Finally, the squat can be effective in developing hip, knee, and ankle musculature, because moderate to high quadriceps, hamstrings, and gastrocnemius activity were produced during the squat." -Escamilla RF

"In conclusion, there is scant evidence to show that deep squats are contraindicated in those with healthy knee function." -Schoenfeld BJ

Bottom Line

The squat can be a very valuable exercise for both rehab and performance.The question isn't about whether squatting below parallel is good for people.  We know that squatting below parallel affords many benefits and few risks.The questions has to deal with what the individual's environment and lifestyle has done to them over time (ontogeny).  What are the patient's physical limitations and adapted structures developed to deal with?  Which ones can you change?  Which ones should you change?Understanding the phases of the squat and the associated forces/EMG activity will help one prescribe the exercise more effectively.Part I deals with understanding the deep squat.  Part II will deal with implications for rehab, performance, and how to train it from the ground up.

Dig Deeper

Evolution:Evolution goes much deeper than phylogeny and ontogeny.  Ontogeny is an umbrella term that includes many more detailed concepts (e.g. phenotype plasticity, epigenome, etc.).  Special thanks to the great professors who helped clarify some of these concepts for me: Daniel Liberman, Robert BoydKathleen Smith, Jennifer Brisson, Jean-Jacques HublinSquat Stuff:Brad Schoenfeld has some of the best articles on the deep squat.  Best place to start in my opinion.  Scroll down for the articles - The Biomechanics of Squat Depth, Squatting kinematics and kinetics and their application to exercise performance .James Speck - 5 Reasons to Start Full SquattingChris Beardsley - Squat Depth for Glute Activation, Squat DepthBret Contreras - 7 Reasons to Squat Like a ManHuffington Post - Nick EnglishStrongfirst Front SquatDean Somerset - Do You Need to Squat DeeplyKevin Neeld - The Truth About Deep SquattingVincent St. Pierre - Are Deep Squat SafeNick Tumminello - 7 Reasons This is a Ridiculous MythMenno Henselmans - Partial ROM vs. Full ROMBrent Brookbush - A Kinesiological Approach to the Overhead Squat (16 Video Series)

- May Hits -1) Do you know about the anti-icing movement?  Many are advocating against cryotherapy post injury.  Some blindly jump on the bandwagon, some feel threatened and become defensive, and most of us just want to know why.  I've recently come across a couple great articles on the theory and evidence that explains why we should not ice injuries.  Even if you continue to ice, you should at least know what it really does (e.g. numbing effect, descending modulation, body temp regulation, placebo).

Dr. Minkin, Josh Stone, Kelly Starrett, Jeff CubosSportsPhysio, Aaron Hutchins, Poor Rats

• To sum it up "Groceries In, Garbage Out"

• Groceries In - inflammation brings in tissue healing cells, ice prevents the flow of these important cells

• Garbage Out - icing actually constricts the lymphatic vessels, pushing the inflammatory proteins out from the lymphatic vessels and back into the interstitial space - the muscle pump is best for reducing swelling/inflammation

"explaining and reconceptualising pain is the best approach we have to treating chronic pain.  However one of the barriers to doing this is health literacy."

“we treat processes, not anatomy”

"Conceptual change, while a type of learning, can be differentiated from other types of learning as it requires a fundamental change in the content and organisation of existing knowledge as well as the development of new learning strategies."

"Pain = (credible evidence for danger) – (credible evidence for safety)"

"central sensitisation patients are not heat sensitive (unlike in peripheral sensitisation – think sunburn and a hot shower) but can be cold sensitive."

“pain is always equally real, regardless of any process of peripheral or central sensitisation”

"neurons that fire at a theta rate are inhibitory "

“Pain is a multiple system output constructed by an individual pain neurotag. This signature is activated whenever the human concludes that body tissues are in danger and action is required and pain is allocated an anatomical reference in the virtual body”

"In chronic pain, thoughts alone can be enough to fire a disinhibited neurotag and elicit pain." 

"Increased activity in the SNS can add to the “inflammatory soup” in an unhealthy tissues, can activate Abnormal Impulse Generating Sites (AIGS) and can dribble out adrenaline into the dorsal root ganglion leading to upregulation of adrenoreceptors." 

"in chronic pain, neurotags can become both sensitised – easier to fire off with a wider variety of ignition cues at lower intensities, and disinhibited – imprecise and less refined."

"Explaining pain is not ‘advice to be active’, but rather explaining the benefits of activity.  Explaining pain is not advice that ‘hurt doesn’t equal harm’, but rather explaining why hurt does not equal harm."

Use Hypnotic Language

"The extent to which a person can recall precisely what occurred during the event, even down to the angle of their feet, the extent to which their knees were flexed etc, may provide a clue as to how precise the protective encoding is within their brain."

25) People You Should Know - Shirley Sahrmann created the Movement System Impairment Syndromes - a big influence on many of today's physical therapists (whether they know it or not).  Path of Instantaneous Center of Rotation and Relative Flexibility/Stiffness are some great concepts that can be used with every patient.26) Top 3 Tweets

4 Mistakes People Make with the Functional Movement Systems (FMS/SFMA)

I am a big fan of the FMS (Functional Movement Screen) and SFMA (Selective Functional Movement Assessment).  Together these screens and their associated principles make up the Functional Movement Systems.

I've been using this system for a couple years and have had a lot of success with it.  The more efficient I become at this approach, the more my outcomes improve.

I still have much to learn and am by no means an expert, but I thought I'd share the 4 biggest mistakes I see people make with the Functional Movement Systems.

4 Functional Movement Systems Mistakes

1) It's Not a Kinesiology or Biomechanics Test

The SFMA and FMS are both seven baseline movements that are used to assess how someone moves.  The big point here is that this is not a kinesiological test or a biomechanical test.  It’s not a strength, stability, or a mobility test.  It is not a test for anything in isolation.

It’s a complex neuro-based movement assessment.  It incorporates all the peripheral inputs coming into the CNS (mobility, muscle tension, joint ROM, position, tensegrity, vision, vestibular, etc.).  It incorporates how these inputs are analyzed and processed in the CNS (movement history, expectations, motivation, ANS state, etc.).  And then, it incorporates the output of this process - the physical movement we can see.

Based off of Louis Giffords Mature Organsim Model - How Movement Goes From Inputs to Outputs Via the CNS

Essentially, the top tier tests are screening your neuro-tag for a standard 7 movements.  It shows what movement looks like in your brain.  It shows how the inputs are processed into outputs.  And this happens continuously in real-time throughout the entire movement.

This isn't just a theory.  It's how human movement works.

Anytime you loosen up someone's ankle DF (inputs), it needs to be integrated in the CNS (processing) for the specific movement pattern that was dysfunctional (outputs).  Sometimes this will spontaneously happen after creating mobility, other times you need to "show" the brain the new mobility and create the new movement neuro-tag.

2) 7 General Movement Standards

One of the big complaints I hear is that “people do more than just 7 movements”.  While this is a brilliant observation, it doesn’t debunk the system.

We can all understand Bernstein's Problem (Degrees of Freedom Problem).  The amount of freedom of the joints, coupled with the kinetic pulls of all the different muscles/fascia/connective tissue, basically creates an infinite amount of possible ways to move.  Therefore, the nervous system has an infinite amount of motor programs to choose from.

In other words, with the plethora of variables in human movement, there cannot be just one "right" way to move.

And this is a good thing; it allows our species to have more options to choose from when trying to adapt to a specific environment or task.

The problem exists in the practitioners job of assessing the infinite.  How do you go about testing the infinite ways of movement in a 45 minute eval?

This is where the SFMA/FMS comes in.

It is simply the best standard we have for efficiently screening the infinite movement patterns.

It is a funnel to find the dysfunctional movement family.

How does this apply to your patient's specific problem?

Simply look at the variables associated with the movement screen and match it with the patients dysfucntional movement or functional complaint.   You should be able to find something in common with your patients specific movement problem and one of the 7 movements (FMS or SFMA).

An example may help understand this concept.

If a patient fails MSF (Multi-Segmental Flexion), it means that this individual will likely have difficulty with movements that shift their COG behind their BOS, or lengthen a their posterior chain, or involve a hip hinge, or involve lumbar flexion, or require motor control of trunk flexion, etc. (see picture below for everyday common movement patterns).

It doesn't only mean that they can't touch their toes and fail a test.  It doesn't mean they need to move exactly like the MSF screen every time they bend forward in their life.  It just means their MSF movement pattern is dysfunctional and this will likely affect many of the other infinite movements that share the same variables.

In other words, it narrows the infinite and points you towards a family of movement patterns that need work.

The Flexion Movement Pattern Family - each one of these movements have something in common with the SFMA MSF Movement Pattern

3) It’s More Than Screening for Impairments

A common misconception about the SFMA is that it's only used to find local impairments.

Yes, finding the local impaired segment and tissue dysfunction is important.  But what’s more important is how the local impairment affects the global movement pattern.

Impairments cannot exist in a purely isolated fashion.  Impairments only exist in the context of the whole human body.  It’s not until the impairment adversely affects a movement (or posture) that it becomes a problem.

For example, an isolated latissimus dorsi restriction doesn’t mean anything by itself.  There are plenty of people who sit at desks all day, don’t exercise, and never lift their arms overhead.  Therefore, this impairment rarely becomes a problem for them.  But if this same person goes out and tries to hit a tennis serve over the weekend, this becomes a serious impairment that affects their MSE (Multi-Segmental Extension) movement pattern.  Compensations will occur and the risk of injury will increase.

Yes, the lat restriction is important, but it only becomes a dysfunction in the context of movement.

The goal of they system is to determine the local impairment AND the movement patterns that are most significantly affected.

A local latissimus dorsi restriction doesn't mean much when sitting at a desk, but it becomes a big problem in the context of a tennis serve

4) It's a Screen & Assessment, the Intervention is Wide Open

This mistake often occurs as a result of the first 3 mistakes.

Most people are able to address the local impairment, but some have difficulty integrating this new input into the movement pattern.

The movement pattern intervention is basically an application of the concepts to the individuals specific assessment.  There is no cookie cutter protocol to follow.  It's open to the practitioner, the client, the environment, and the task/goal.

If you understand that it’s a complex neuro-based movement system, then you can understand there are an infinite amount of options to achieve the same result.  First address the breakouts (inputs), then integrate them back into the global movement pattern (processing), and finally re-assess the movement pattern (output).

Gray Cook has discussed this process in his 3 R's approach: Reset, Reinforce, & Reload.

Again, it helps to first think of it as a family of movements patterns.  Try to create similar sensory inputs that are “relatives” of the top tier movement pattern.  They don’t have to be identical twins, you just have to be able to tell that they’re related.

If the patient fails MSF, address the local impairments, then integrate them back into the movement pattern.  To do this, just pick an exercise that shifts their weight back, or flexes the trunk forward, or eccentrically lengthens the posterior chain, or rounds the lumbar spine, or requires a hip hinge.  Or a combination of those variables.

The same thing goes for the FMS.  If the patient fails the hurdle step, work on something that stabilizes the stance leg in hip extension, or open chain hip/knee/ankle flexion, or the scissored position (hip flexion & extension), or work on something that stabilizes the trunk upright in the dysfunctional scissored position.  Or a combination of those.

What you choose as your intervention should depend on the results of the movement screen, the breakouts, the examination, your patient, and your own treatment style.

If this open territory makes you uncomfortable, the System has a nice 4x4 exercise progression based on the neurodevelopmental perspective.  This may be the closest thing you will find to a "protocol" for movement patterns.

In the end, it doesn't matter what approach you use to address the findings in the screen and assessment.

There are many different ways to achieve the same thing.

As long as it simulates the similar inputs of the movement pattern, you should get a positive change.  If you don’t get a positive change, the screen will tell you.

And this is may be the most valuable aspect of The System.  It allows for you to "check your work".  It gives a clear indication for which interventions work, and which ones don't.

The System allows you to methodically add and subtract interventions until you achieve the desired outcome.

It gives you efficiency and effectiveness, while taking nothing from the way you currently treat.

Hurdle Step Movement Family - Which one your patient needs depends on their movement assessment and breakouts

Bottom Line

The Functional Movement Systems is a very useful clinical tool.  There is much more to this approach than simply screening 7 movements.  Understanding the concepts and principles of this approach will help to prevent errors and increase efficiency and outcomes.

This means that, for example, sensory information from the eyes can change how something tastes, or that sensory information from the ears can affect how something feels." - Todd Hargrove on the Marble Hand Illusion Study7) "A dissection study by Gibbons and Mottram (2004) found a 3rd layer situated deep to the previous 2 described with short fibres that cross the sacroiliac joint (SIJ) and have relations with multifidus, the deep hip intrinsics and the pelvic floor."  They call this layer the Deep Sacral Gluteus Maximus.8) "the language of movement is written in feel, not in words or pictures" - Gray Cook goes over when to coach and when to correct9) How many patients do you see that get injured because of the elliptical?  Seth Oberst goes over why this isn't the ideal "exercise" for your patient in this post.  "When we can't feel the ground, we adapt thru maladaptive co-contraction (like walking on ice) in the leg musculature reducing movement efficiency for when it matters most - like doing actual athletic or sport movements, even walking."10) Subjective history may not always be accurate.  "Every time you pull up a memory, say of your first kiss, your mind reinterprets it for the present day, new research suggests. If you're in the middle of an ugly divorce, for example, you might recall it differently than if you're happily married and life is going well."11) Short muscles are a problem.  Not because of adaptive restrictions, but because of the vicious neuromuscular cycle.  Muscles that are in a shortened position often have increased neural drive (neural activation).  This means they often become over facilitated and need to be inhibited...not stretched.12) Bridge Progressions from Chris Johnson.  I particularly like the variation on the 2nd exercise and have started prescribing it in my practice.13) Interesting study on rotator cuff repairs: "Patients who underwent rotator cuff repair have improved function and reduced pain, regardless of the structural integrity of the repair. Patients with an intact repair have greater strength than those with retears."14) It seems like mobility is getting all the credit these days.  And for good reason, tons of mechanoreceptors, allows for fewer compensations, centration, motor control, core pendulum theory, correlated with lower morbidity, etc.  But what about good ol' fashion strength?  Strength is an important physical characteristic that allows your patients to move better and increases their ability to adapt to physical stress.  Think about your older patients.  If they're having trouble going from sit to stand, is an ankle mobilization or lower extremity strengthening program going to help them more?  Recent research is now backing up the importance of strength in regards to mortality.  Don't forget to get people stronger.15) I wish this would have been around back when I took biology.16) "Sleep complaints are present in up to 88% of chronic pain disorders and at least 50% of patients presenting with insomnia also suffer chronic pain."17) Lifestyle has a great influence on recovery.  Here are 4 lifestyle choices that I like to discuss with my patients.18) During my last affiliation of PT school my CI, Marcus Forman, used to always preach that "the devil is in the details".  He was right in more ways than I could have imagined.  Mike Reinold goes over the details of the simple hip flexor stretch.  Don't let your patients hack up this stretch.19) Erson's 5's - 5 Things Your Patient Needs for Successful Outcomes: Education, Mobility, Symmetry, Stability/Motor Control, Homework.  5 Cervical Radiculopathy Treatments - I've recently been amazed at how well kinesiotaping works for symptom relief. - 5 Modern Ways to Look at Manual Therapy20) A review of pain from Move Forward.  A physical therapist's guide to understanding pain.21) I wrote up this article on grip strength and the rotator cuff for Physiospot.22) Eric Cressey gives 5 tips for people performing/teaching boot camp class, crossfit, and/or other metabolic resistance training classes.  This can improve performance and decrease risk of injury for those participating in these types of classes.23) I'm a big fan of Adriaan Louw and his work.  Zac "Review Machine" Cupples wrote this up about his course (including a great Predator reference).  I've always liked the ion explanation: "When someone is extra sensitive, the nerves increase their resting excitement level so action potentials more readily occur. Adding more ion channels to less myelinated areas can further compound this sensitivity.  Fun fact – Ion channels change every 48 hours, and therapy can positively influence the change."24) Nice review of Andreo Spina's course - "The longer the muscle is when it is contracted, the more force through the tendon/connective tissue at the attachment site" - "All connective tissue (muscles, bones, fascia, etc.) are all just different expressions of the same material."25) People You Should Know: Nikolai Bernstein is the one of the Godfathers of motor control and motor learning.  Read about his Degrees of Freedom Problem ("Bernstein Problem").26) Top 3 Tweets of the MonthTim Cocks (@altThinq) live tweeted some great stuff from Explain Pain 3.  Look at #ExplainPain3.

  • @medicalaxioms - It takes considerable knowledge just to realize the extent of your own ignorance. –Thomas Sowell

The Art of Recovery (Part 2 of 2)

Part I went over stress, tissues, the nervous system, and many of the factors that are involved with recovery.Throughout a PT session there are many opportunities to influence the patient's health; both for the immediate and long term effects.  This post will go over the 4 factors of recovery that I often try to discuss with patients before they are discharged from Physical Therapy.

4 Factors of Recovery

Each of these 4 factors could be a book on its own, let alone a blog post.  To save myself some of the mental stress of going over each of them in-depth, I'll just briefly describe the factors and some methods for improvement.Before you start educating patients, it's important to follow the golden rule:

  • Don't prescribe anything you haven't tried yourself

This goes not only for exercises, but the lifestyle changes as well.  If you don't sleep well, have never meditated, and eat bad food, then you shouldn't try to influence other people.

Sleep

Sleep is a difficult one.  Going to bed at a descent hour is extremly difficult these days.  Youtube, reddit, twitter, league pass, and Netflix (how can you just watch 1 episode of House of Cards?).  But it's one of the easiest ways to improve recovery.Sleep gives us the lowest level of stress (internal & external) on the body.  This low level of stress allows us to get out of the red and into the black.  It lets us recover.  Both mentally and physically.The science behind sleep (and why we need it) is still not conclusive.  But we do know that sleep plays a huge role in hormone regulation (melatonin, GH, TSH, testosterone, cortisol, etc.), augments immune system function, improves cardiovascular function, increases cognition, and improves neural function (stimulate oligodendricytes, myelin, neural development/repair).  Plus, the supine position puts the lowest load on the body.Sleep expert at NIH, Dr. Michael Twery, sums up these benefits of sleep nicely; "Sleep affects almost every tissue in our body."So even if we don't know all the reasons behind why we sleep, we at least know that it's good for you.Most experts agree that you need at least 7 hours of sleep a night.  Of course it varies from person to person, but if you're getting less sleep than 7 you might have trouble recovering from the day's cumulative stress (especially if you've put extra stress on it; i.e. workout, injury).

Improving Sleep

 Take an active role in improving your sleep

Mental Stress

Today's culture creates quite a problem.We have these bodies that were developed from over 6 million years of evolution.  This slow, progressive, evolution of our physical body has given us the genes we have today.  Even though we've become a different species than our ancestors, we still share many of the same genes.  Thus, we share a similar body type as our ancestors.On the other hand, our cultural evolution has skyrocketed in the last 10,000-50,000 years, leaving our physical bodies way behind.  And this cultural evolution continues to progress at an exponential rate.  The Agricultural and Industrial Revolution were the first big events that changed the way humans live.  Now we have the Information/Telecommunications Revolution. We are spending more time plugged in and less time present with our bodies.  From this cultural evolutionary perspective, we don't share much in common with our ancestors.The difference in physical and cultural evolution has created quite a problem for our species.This creates a mismatch between the environment we live in and our physical bodies.  In other words, our bodies are not made to live in today's cultural environment.The result of this, and the fact that we often treat the symptoms instead of the cause, is what Daniel Liberman refers to as dysevolution.  A product of this dysevolution is the increasing amount of mental stress/disorder and physical dysfunction.Luckily for us, there is a method to help prevent or decrease this mental burden - Meditation.

Meditation

Meditation has been around for possibly 5,000 years.  Needless to say, it has some empirical evidence.I have taken UCLA's on-line meditation course with mindfulness expert, Diana Winston.  While this by no means makes me an authority on the subject, it has educated me on some of the science behind meditation and how to apply it.The benefits of meditation are incredible and the profound effects cannot be overstated.  Many people talk about the life changing effects of this practice.  Even some of the most successful people in our society have credited meditation as a big part of their growth and accomplishments.But even if empirical evidence doesn't convince you, modern research has shown many positive effects.

Research Has Shown That Meditation Can

  • Improve Physical Health (e.g. cardiovascular, immune system)
  • Improve Mental Health (e.g. anxiety, depression)
  • Improve Emotion Regulation
  • Decrease Sympathetic Drive
  • Improve Attention (e.g. conflict attention, improve flow)
  • Improve Brain Function (e.g. neurodevelopment, gyrification)
  • Decrease Pain
  • Improve Well-Being

Sounds pretty good, right?And did I mention that it's free and easy?  Well...it's free and physically easy.  Developing your meditation practice is a process and requires some motivation and mental effort.  But don't take that as a deterrent, it's not exhausting or mentally fatiguing.  In fact, most people feel energized after meditating.  The most difficult part is getting started and developing the habit of meditating.I think one of the best places to start is with Diana Winston's 5 minute breathing meditation (YouTube).This is a great place to start for 3 reasons:

1) Everyone can perform 5 minutes

2) It goes over the basics and gives you a standard guideline for future meditations

3) The diaphragm is the only voluntary muscle that can directly influence the autonomic nervous system.  Breathing augments the parasympathetic response of meditation.

It's important to note that I don't immediately jump directly from discussing a painful shoulder to giving them a 5 minute meditation recommendation.Before I prescribe meditation to a patient, I first educate them on the autonomic nervous system continuum (sympathetic vs. parasympathetic).  Then I begin to explain some of the benefits of meditation and how it can aide in their recovery.  If they are receptive, I simply write down my meditation recommendation (above), tell them to type it in on google, find a quiet place, and try the 5 minute meditation.One benefit of our accelerated cultural evolution is that there are now plenty of meditation guides, timers, apps, and techno-bio-feedback devices that give people an easy way to stay on top of their meditation practice.

Diet

Bringing up diet is a lot like bringing up politics.  Everyone has an opinion and no one knows what's really going on.Do we eat nothing but bacon?  Is carbohydrate a bad word?  Is there a chocolate diet?However, more science and less propaganda has allowed for a recent paradigm shift in diet.  We're only scratching the surface and the answers will vary per person and per culture.  But it has gotten a lot better than that terrible food pyramid we were taught to believe.Trends will come and go, but I feel that there are 5 facts that would help most people.  Of course there are a lot more to these "facts" than a simple sentence, but hopefully it'll give some direction for nutrition choices.

5 Nutritional Facts

  1. Avoid Processed Foods
  2. Eat More Vegetables
  3. Avoid Simple Carbohydrates
  4. Fat is Not Bad for You*
  5. Stay Hydrated

I don't think these 5 Facts will change as they seem to be backed up by basic physiology, logic, and evolutionary medicine.  We may learn more about the specifics of each category, but the basic principle shouldn't change.  For example, it is now well known that fats are good for your health, but research is finding out which specific types of fats are healthy and which are detrimental (i.e. trans fats).

Exercise

The benefits of exercise are enormous.  Exercise improves the musculoskeletal system, controls weight, increases life span, reduces diabetes risk, improves mental health, reduces risk of some cancers, improves cardiovascular fitness, and improves sleep.Exercise is also beneficial for recovery both:

• Immediately following a bout of stress

• For the long term ability to adapt to stress.

The immediate beneficial effects of exercise for recovery should be focused on the circulatory system.  The goal is simply to get blood and fluids moving around.  This should include some active dynamic stretching, mobility work, light stabilization, and/or light aerobic exercise.The long term effects of exercise are much more complicated.  This requires specific individualized programming that involves periodization and deloading.  People should have a normal overall fitness and exercise routine to help stress the body for an individualized adaptation.  Because in the long run, the body can only handle what the body is adapted for.There are many great articles regarding the physical aspect of recovery.  Check the references provided below for more detailed information.

Bottom Line

It's often not the over-training, as much as it is the under-recovery.You can have the greatest training program and the best workout session from the best coach in the world.  But unless you are able to recover from it, it won't matter.Bernard Hopkins, record holder for chronologically oldest boxing champion, sums this series it up nicely:

  • "Lifestyle is the make or break of any athlete."

I would even go one step further and say that lifestyle is the make or break of anyone's health.

Disclaimer

Now I'm not saying you should go out and give your patients a full nutritional prescription or start discussing their childhood to determine why their boss stresses them out.  Instead, you should just be assessing the factors that influence their recovery and offering some general advice (if you are educated).  Anything more than this would be beyond health promotion and fall out of the scope of your practice.If someone is interested in a more in depth answer, you should refer out.  The patient will benefit from a greater health "team" and the person you refer out to may even start referring in to you.

March Hits (2014)

- March -1) Communication is just as important as the intervention.  Seth Oberst writes a great post on the difference between external and internal cues.  "It's now being shown that athletes focusing on the results of the movement are producing more force, jumping higher, generating better performance in stressful situations, and increasing fluidity and multi-tasking."2) Evolution has shown us the importance of diet and the jaw on our growth as a species.  Here's an interesting site on the jaw and it's relation to the co-morbidities.3) Want to learn how to pistol squat?  Click here.4) A PRI influenced series on "Unlocking Secrets of the Pelvis (Part IIIIIIIV)" by Robert George.5) The never ending patella vs. hamstring ACL graft battle.  Mike Reinold goes over recent research that showed more revisions are performed on hamstring grafts.  "When we really assess the numbers, it is clear that both graft options are great choices with low revision rates.  Even though we are comparing the two, realistically the revision rates after ACL reconstruction are low for both hamstring grafts and patellar tendon grafts."6) Nice article with some PRI and DNS concepts for abdominal training from Mike Robertson.7) This is some great stuff from Jeff Cubos.  Quotes from Andreo Spina followed by his explanation of each quote.  I also re-read this post from Spina on fascia, solid-state biochemistry, and theoretical physics.  You might not want to speed read through this one.8) More evidence on proximal influence: "...rehabilitation professionals should consider incorporating balance training, as an integral component of core stability, into the rehabilitation of athletes with shoulder dysfunction."9) This sums up our dysfunctional nutrition views: 11 Graphs Showing What is Wrong with the Modern Diet10) Lorimer Moseley on Bioplasticity: "It seems to me to be a fairer reflection of what we know about ourselves and it is a sensible umbrella term for the changes that occur across multiple systems when, for example, pain persists, or when, for example, we try to change pain."11) "We all want our magical hands, brilliant exercises, and genius programming to cause specific advantageous adaptations that give our patients super-human like powers.  But the sad truth is, even if we put a magic spell on a patient, they will only get better if they can adapt from it."  Recovery Drives Adaptation12) Zac Cupples reviews Explain Pain.  Great stuff.  "The therapeutic goal is to alter representations, deactivate painful neurotags, and reduce the perception of threat."13) "Connective tissue is both fluid and container, a sea and a retort, the medium in which chemical re-organization occurs (Juhan). It is fluid crystal, a ‘dynamic rhythmic matrix which operates as conductor for many different kinds of energy: mechanical, elastic, hydraulic, electro-magnetic, gravity, heat, sound and light.’  (Peters).  Shifts in our emotional state are linked to perceptions of a change in the state of our connective tissue, including a sense of flow and ease, or fullness, or lightness, or constriction or density." - Roz Carrol14) If you enjoyed the NFL Combine, you should check this out.  Mike Robertson goes over the strength & conditioning components of each test.15) Advanced Lat Stretch for the athletic population.16) "This shows that the adductors have better leverage as hip extensors in hip flexion, whereas the glutes have better leverage as hip extensors in anatomical position. Also, the sum of hip extension moment arms is greater in hip flexion compared to anatomical position." - Bret Contreras post on hip extension during the lockout phase of a deadlift.  For less adductor activity during extension, try emphasizing extension at neutral.17) 3 Different "Happy" Lives - Martin Seligman

18) Erson interviewed pelvic floor specialist, Julie Wiebe.  Some good stuff here.  4 Gems: 1)“Trust that the body is a self righting organism. Our job is to guide the process.” Norene Christesen, PT.  "  2) "I didn’t make them better, they made changes in how they thought about, used or moved their body and saw results. " 3) "Our stability system actually runs off the breath cycle." 4) "the pelvic floor is parallel in its action to the diaphragm, they work together, so it is important that clinicians know how to integrate them along with the TA and multifidus into their programming for stability, strengthening, balance, etc."19) 1-Arm Offset Kettlebell TRX Rows20) Gait Guys (via Erson) - The Deadmill.  Treadmill pulls the hip into extension, knee into extension, and ankle into dorsiflexion.  The problem is that this passive pull on these joints causes a stretch reflex (muscle contraction) and inhibition of the antagonist.  It robs the user of glutes, quads, and ankle DF.  How many runners do you see that need glute & quad strenth and ankle DF ROM?21) "True movement intelligence therefore doesn’t exist so much in the movements themselves, but in their interaction with the environment." - Todd Hargrove22) Top 3 Tweets of the Month

  • @deansomerset - Knowledge without application = useless. Application without knowledge = dangerous. Always know more than used, never use more than known
  • @DrAndreoSpina - To fully understand human health study human #evolution
  • @PikeAthletics - Strength is an attitude, not only a physical quality.

Note: Some use twitter to promote and sell their products, some use twitter to troll and argue, and some, like @ZBrulet, use twitter to share knowledge and improve movement.  If you have any interest in S&C, you need to follow him.23) WOD of the Day - Snatch and Roll for EmbarrassmentHow not to miss a lift             [subscribe2]
