This exercise can be introduced into a care plan for sciatic nerve inpingement (the nerve which exits the low back and runs through the buttocks and posterior leg). The subtle movement moves the nerve back and forth, similar to that of flossing your teeth.
This exercise hopes to aid relief of symptoms, and is useful for taking pressure off of the affected nerve.
Recommended 10 reps & can be done multiple times throughout the day. Work within tolerance levels, (stop if aggravating symptoms).
Note it is important that this exercise is not introduced too early into the treatment process. Feel free to contact me for more in depth details.
