I must admit, I've never heard of it... but I have a visit scheduled with my neuros this week and I'll query them about it. >> Dystonias are uncommanded steady contractions of a muscle or muscle group. They seem to be connected to L-dopa (sinemet) therapy. A dystonia of my right arm used to happen while I was waiting for my first Sinemet dose of the day to kick in. I knew that about 15 minutes following my rigid, straight, right arm "pulling" it's way across my chest, I would start to feel the slight left wrist dyskinesia that heralded the first serious on period of the day. Incidentally, if my CG would grab my hand and proceed to shake my arm until it shook like a rag doll while I tried to relax it, the dystonia would abate for a while. I believe I stopped having torso (what have been called trunkal here recently) dystonia when I switched from sleeping face down (with my head to the side and on the corner of a pillow.) to sleeping on my back. I remember a picture taken at my 25th college reunion. I was easy to pick out in the picture- I was leaning to the right while the others were standing straight. Regards, WHH 56/38/37
