Retention of EMG Biofeedback Relaxation Training

Abstract

This study investigated how much subjects could retain ability to reduce muscle tension without daily practice and the extent to which periodic re-training would be a practical and effective way of retaining the skill. 19 male and 29 female subjects were given standard frontalis muscle biofeedback relaxation training. After initial training, 34 subjects in the experimental group were further randomly assigned to 3 different re-training groups: re-training once every 2 wk., re-training once every 4 wk., and none. All three groups maintained their ability to reduce muscle tension, and the group given re-training once every 2 wk. further improved that ability.
