Sending out a great THANK YOU to all the folks who took the time to provide the links to some very darkly amusing stories of the modern snake oil sales of this overpriced, over-hyped devices. I had called the hospital neuro- rehab unit and spoke with the head therapist. Never heard a whisper about the thing. Together with the info on this site I am making progress toward being proactive with options which will help. I feel hopeful in a more realistic way. What a great support this site is!! Again many thanks to all and hope this updates the question of efficacy once and for all. Onward...one step at a time....
