A comprehensive look at cervical biomechanics and exercise The Wu-Tang clan once said “Protect Ya Neck,” but how in the heck can you do that if you don’t know the biomechanics?????? The neck can be quite complicated considering all the factors that influence it’s dynamics: Ribcage position Thoracic spine Hyoid bone Cranium Temperomandibular joint OH MY! Yet despite all of these influences, there are simple, useful heuristics you can follow that can lead to favorable changes in neck mobility! Want to make the neck, cranium, and more ridiculously simple to understand and apply? Then tune in for Movement Debrief Episode 125.

Read MoreThe 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
