At a recent PD support group meeting here in Cape Girardeau, Missouri we had a session of relaxation followed by light resistance exercise. During the relaxation phase of the "workout" I found that my tremors (arms and legs) became worse; during the resistance exercises the tremors lessened. However, another member of our group experienced just the opposite; quiet (no tremor visible) until we started the exercises then his hand and arm tremors really got going. Can anyone speculate as to what might cause this difference in tremor reaction to relaxation and exercise? Margaret Mates
