Assuming the question was for me: I produce the StepOver Wand. A small gadget that does magic for my walking. It enables me, and other parkinsonians, to walk (rather than shuffle), when we are in an "off" period, It helps avoid "freeezing" in small spaces, when crossing doorways, in entering elevators, when the phone rings and we are home alone and the phone is in the other room, and other goodies. I have had parkinson's disease for 18 years and I am finally independent and mobile again. I am just getting familiar with internet addresses and if I am reaching the wrong party, other then the parkinson group, I beg your pardon and I SEND MY APOLOGIES .Lisa.
