In a message dated 5/16/97 6:23:03AM, you write: << 1. Sometimes the "turn-on" is not received; this shows as paralysis. 2. Sometimes the "turn-on" is received, and confirmed, but the "turn-off" signal is not received; this shows as cramp. 3. Sometimes the "turn-on" is received, but the return confirmation is not received, and so the signal is repeatedly sent; this shows as tremor and jerking, as in "restless legs" syndrome. 4. Sometimes the "turn-off" is sent, but the return confirmation is not received, so the deactivating message is still enforced; this results in the "floppies". This last effect is, in my experience, more rare. >> Jim, I hope Frances will forgive me for butting in, but I seem to have lost the original posting, and have only read your response. I am particularly interested in your description of the 'floppies'. I am 45 and have not been diagnosed with PD, but have calcification of the basal ganglia, which apparently produces a Parkinson syndrome. However, my problem is more weakness and intermittent floppiness, with episodes of virtual paralysis, when only my eyelids flicker and wrists and hands twitch. I would really appreciate any more information you could supply regarding this, as I am finding this prelonged period of non-diagnosis very trying. My symptoms also include fatigue, double vision, blurred vision, joint pain, sensory disturbances, dragging feet when tired. I apologise once again for butting in, Sue Bunce
