Summary:The purpose of this investigation was to assess biofeedback (BF) and progressive muscle relaxation (PMR) and placebo-control training by means of a post-training transfer test. The subjects for the research were 30 women. Initial tests consisted of measuring the electromyographic response of the frontalis muscle of the forehead to stress. After the test procedures were completed, training sessions were conducted. BF subjects were instructed to use a feedback tone as a guide for relaxation. PMR subjects heard progressive relaxation instructions that were modified so that the majority of the training instructions were directed specifically to the frontalis muscle. The group of subjects receiving placebo training listened to a short, taped presentation on the benefits of relaxation after which they heard music that fluctuated in volume and tempo. Results showed that both BF and PMR training reduced resting electromyography significantly more than the placebo-control procedure. BF subjects had significantly greater reductions following training than either the PMR or control groups. (JD)
