When I took an electro-cardiogram a few years ago, even though I didn't show tremors, the muscle tremor was clearly present on the tape. My doctor commented that he had learned in medical school about this "typical" pattern for people with PD. >From: Randy L Vinecore <[log in to unmask]> >Reply-To: Parkinson's Information Exchange Network ><[log in to unmask]> >To: [log in to unmask] >Subject: Re: Chaos Theory & tremor >Date: Fri, 7 Apr 2006 03:27:16 -0700 > >Some of us dont present with visible tremors, although at times there is >this internal feeling that they are present.
