Video - study on differential movement of the sciatic nerve and biceps femoris muscle.

This study has implications for diagnosis of a sciatic nerve aspect to hamstring injury and tendinopathy.  In our study on cadavers, the sciatic nerve moved independently of the biceps femoris muscle when dorsifexion of the ankle was applied to a stationary straight leg raise.

Opening and Closing Around the Tibial Nerve at the Ankle

Here the ankle (tarsal tunnel actually) forms the interface for the tibial nerve.  It is possible to produce openers and closers for nerve health in this location.  
LEFT: the large dark band is the neighbouring vein, the behaviour of which is a good indicator of the pressure in the area because it collapses and expands with small changes in pressure.  If the vein collapses, the area is under pressure.  Opening of the vein indicates a reduction in pressure.

The nerve is immediately below the vein and note that it too becomes bigger when the pressure is reduced.

Learning How to Move the Ulnar Nerve

Demonstrated in the video below is how, with the right feedback, the patient can learn to move their nerve in less than a minute.   Initially, it is somewhat chaotic but, as time passes and the subject learns, the nerve movement becomes more and more precise.
LEFT: the nerve is the band going across the top third of the screen.  Note that the nerve has two main fascicles with what seems like a septum (interfascicular epineurium) dividing them in the middle.

Specific Movements of the Median Nerve at the Wrist

Effect of Manual Technique on the Brachial Plexus
LEFT: This video is an example of the importance of precision in which too much movement could produce a false positive with neurodynamic tests.

As we get better at testing, we not so much find more positives, but we produce fewer false positives.  This means we are getting better at excluding neurodynamic problems.

Brachial plexus at the costoclavicular space - effect of scapular elevation
LEFT: the dark areas on the top right and lower middle of the screen are shadows produced by the clavicle and first rib respectively.

The bands across the mid-screen are the brachial plexus which undergoes changes in pressure when the costoclavicular space is opened or closed.

The costoclavicular space opens with elevation and closes with depression of the scapula.
