I just went through off-on testing at Mohammad Ali research center in Phoenix. It is an impressive facility with great staff. However I am wondering why there isn't a more accurate method that doesn't require as much MD time and subjective interpreting.
I think it would be simple to fit the patient with gloves socks and a cap with motion detecting sensors. A few more sensors at the trunk and knees and elbows could also be applied. The resting activity as well as all functional tests both off and on would be recorded by a computer. A simple home unit with an ipod could keep track of our daily fluctuations and indicate the best med formulations.... we would only have to record the time and dose of meds. Tremors, freezing, balance gait... fluctuations, everything would be there. Sometimes I feel like an idiot when describing my situation to the Docs.
