This is a chapter 10 summary of the book “Movement” by Gray Cook. Mistakes, I’ve Made a Few When we are talking corrective exercise design, people often make 4 mistakes: 1) Protocol approach: Exercise based on category. Problem – 1 size fits all. 2) Basic kinesiology: Target prime movers and some stabilizers. Problem – fails on timing, motor control, stability, and movement. 3) Appearance of functional approach – Use bands and resistance during functional training. Problem – If the pattern is poor, adding challenges to it can increase compensation. There is also no pre-post testing. 4) Prehabilitation approach – Prepackaged rehab exercises into conditioning programs as preventative measures to reduce injury risk. Problem – Design is based on injuries common to particular activities as opposed to movement risk factors. There are also certain mistakes that are often made when utilizing the FMS and SFMA: 1) Converting movement dysfunction into singular anatomical problems. 2) Obsessing over perfection in each test instead of identifying the most significant limitation/asymmetry. 3) Linking corrective solutions to movement problems prematurely. The overarching rule is to address these movement deficiencies first, as we do not want to put strength or fitness on top of dysfunctional movement. The Performance Pyramid When designing an exercise program, we look for three areas to improve performance: Movement, performance, and skill. It is important that program design is based on the individual’s needs and has these qualities in a hierarchal fashion. For example, if one performs excellent on functional performance

Movement Chapter 8: SFMA Assessment Breakout Descriptions and Flowcharts
This is a chapter 8 summary of the book “Movement” by Gray Cook. What to Look For The SFMA breakouts are utilized to determine if one’s movement deficiencies have a mobility or stability origin. There are further possibilities in each of these categories. It Could Be a Mobility Problem There are two subsets of mobility problems that include tissue extensibility dysfunction (TED) and joint mobility dysfunction (JMD). From here, we can break it down even further in each subset. Here are some potential TEDs Active/passive muscle insufficiency Limited neurodynamics (they said neural tension; come on Gray!) Fascial tension Muscle shortening Hypertrophy Trigger points Scarring/fibrosis And here are some potential JMDs Osteoarthritis/arthrosis Single-joint muscle spasm/guarding Fusion Subluxation Adhesive capsulitis Dislocation It could be a Stability Problem These issues are also known as stability or motor control dysfunction (SMCD). Most conventional therapies would treat these complaints by strengthening the stabilizers, but this is problematic. When something works reflexively, how can we train something volitionally and expect changes? To train these muscles we must focus on proprioceptive and timing-based training. There are several examples of SMCD problems. Motor control dysfunction. High threshold strategy. Local muscle dysfunction/asymmetry. Mechanical breathing dysfunction. Prime mover or global muscle compensation behavior or asymmetry. Poor static stability, alignment, postural control, asymmetry, and structural integrity. Poor dynamic stability, alignment, postural control, asymmetry, and structural integrity. Relatedness Mobility and stability can influence one another. If I were to lose mobility at one segment, motor control can be distorted at nearby segments.
