Abstract

Two subjects exhibiting drug-induced hand tremor received EMG feedback from electrode sites above the forearm extensor muscles . EMG feedback resulted in reductions in muscle potentials for both subjects. However, self-report measures of tremor severity showed only general improvement in Subject l and little or no improvement in Subject 2. Behavioral measures of hand steadiness taken immediately after each treatment session showed slight changes across treatment conditions for both subjects. As indicated by a rapid increase in EMG measures during reversal, treatment effects appear transitory.
