I am a physio. I have studied the nervous system. Their claims are rubbish. I have a family member who was injured badly there. Yes, they are seriously charging too much for everything. Exercise is great therapy for all ills - they help people exercise, but at what cost? How you can claim to rejoin a severed spinal cord and aid other serious neurological conditions with the vibration therapy. If there is 'research', it is probably of poor quality - getting something published means nothing. Plenty of papers published that are bull-dust - that is their category. My opinion. Stay away.
