Electromyographic biofeedback for tension control during gross motor skill acquisition.

This study investigated the effects of tension-control training by electromyographic biofeedback on learning and performance of a stabliometer balancing task. 30 young adult males were pretested for stabilometer balancing skill, ranked by performance scores, and divided into identical triplicates to form two experimental groups and a control group. All subjects were reevaluated on the stabilometer test following feedback training of the experimental subjects. Analysis of variance of difference means, scores representing performance and tension, indicated that the biofeedback training significantly reduced tension induced by the novel motor skill and significantly improved performance of the motor skill.
