Abstract
This study examined the effect of EMG biofeedback with concentration on trapezius muscle relaxation. Fourteen college students were randomly assigned to biofeedback (BF) group (5), concentration (C) group (4), and feedback-with-concentration (BF-C) group (5). While the BF group wasrequiredto relax the muscular tension based on auditory biofeedback, the C group was asked to relax using concentration on the sensation of muscular tension without the biofeedback. The BF-C group was asked to relax using both the biofeedback and the concentration. The concentration was induced by a task of successive discrimination between muscular tension and relaxation. The experiment was consisted of 6 traiLing sessions (for 6 days), and 2 follow-up sessions. As the main result, the BF-C group showed a significant decrease in EMG compared with the other 2 groups. Scores of the discrimination task of the BF-C group were significantly higher than those of the other 2 groups. Implications for biofeedback with concentration on trapezius muscle relaxation training were discussed.
