Such a suggestion is a new one to me, but if your doc has said the possibility exists Yellow, I would not challenge the hypothesis.... my situation has never caused such drastic involuntary movements; however, I have noted when lying on my bed with the legs above the comforter.... if I just sit still and watch, kinda like bird watchin you know? THEN I notice my toes do involuntarily move, and I cannot make them move, so the stim is doing the kick in the kaboodle.
So back to that witness stand I have talked about before, and only because I have seen no case law reported regarding a decision on use of stim while driving as causation of injurious wreck on roadway..... imagine being asked the question "so, the stim you have, was it powered on at the time of the incident while you were driving?" If you do not want to have to answer questions like that one, prepare yourself accordingly.
This thought, two cents, and a nice smile will not purchase a thing, but......
