The present study is concerned with EMG-biofeedback in writer's cramp. Two patients of tremor type, three of stiff type and two of dystonia type were instructed to penmanship with the EMG-biofeedback procedure to decrease EMG-amplitudes at writing.In the tremor type and the stiff type writer's cramp, practice effects appeared, and the EMG-amplitude was decreased. No effect was seen, however, in the dystonia type. In the tremor type even though good practice effect was seen, surface EMG showed that tremor was continuing. Therefore, we conjectured that EMG-biofeedback therapy was effective in the stiff type.Regarding the results that each type of writer's cramp had its own pattern in response to EMG-biofeedback, we suspected that there were different psychophysiological or neurophysiological bases amongst various types of writer's cramp.
