Motion Specific Release (MSR) treatment for PN?

Is anyone familiar with or have had MSR (Motion Specific Release) treatment for PN? My daughter-in-law who resides out of state is a PT. She uses it quite often in treatment for people who have had falls or been in car accidents. It treats neural tension where the nerve gets entrapped or is basically rubbing through an area of tight fascia and muscle. I believe the treatment was originally developed by a chiropractor, and it is now being used by PT’s who have been specifically trained in this modality. I have been diagnosed with IPN and have painful muscles in my lower legs as a result. It is difficult to take walks as the pain is always there. I was diagnosed through an EMG. I do not take pain relief prescription medication because these cause side effects for me.
