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.

The Sensitive Nervous System Chapter XI: Neurodynamic Testing for the Spine and Lower Limb
This is a summary of Chapter XI of “The Sensitive Nervous System” by David Butler. Intro For today’s chapter, I have decided that the best way to learn these tests is to show you. I will write in any pertinent details you need for a good test performance. The Straight Leg Raise (SLR) SLR hacks. Add sensitizers (dorsiflexion, plantarflexion, etc) to determine nervous system involvement. Add cervical flexion or visual input to enhance responses. Be mindful of symptoms before and after pain responses. If this test is positive post-operation, it will likely be inflammatory in nature. You can preload the system further with cervical flexion or sidebending the trunk away from the test side. Here are some other ways to perform the SLR with sensitizers first. (I apologize for the way the camera shot in advance). For tibial nerve-bias. For fibular nerve bias. For sural nerve bias. Passive Neck Flexion (PNF) Here is how to perform the test. PNF Hacks. Add SLR to further bias the test. Be mindful of Lhermitte’s sign, which is an electric shock down the arms or spine. This is a must-refer sign as there is potential spinal cord damage. Slump Test Here is how to perform the slump. Slump Knee Bend In the book itself, Butler uses the prone knee bend as his base test. However, NOI does not teach this motion as much and now favors the slump knee bend. This movement allows for much more differentiation to be had. And the saphenous nerve
