Dr, I am an "early" PD patient--age 47-diagnosed approx 4 years ago--on relatively low dose Stalevo--although initially coordination was only affected in my left arm, hand--relatively soon I noted an intermittent l leg driven gait asymmetry. Post-diagnosis I had several lumbar disk surgeries- ?necessary. After years of concentrating on this gait disturbance and reading I have narrowed down the main problem (I think). During "off" periods" I have hypomobility/apparent weakness of l foot extensor hallucis longus function that is not associated with any dystonia and DEFINITELY improves with meds. Has this been desccribed? do you think there is an element of true neuropathy? and is there anything you can think of to improve EHL strength? When I do exercises for my toes/feet/ankle do you think I should concentrate on "on" or "off" periods?
