Abstract

The present study evaluated multiple system physiological responding which accompanied EMG biofeedback performance under two conditions - during EMG biofeedback training sessions, and during the utilization of that training in the presence of a stressor. Twelve subjects were randomly assigned to one of two groups: an EMG biofeedback group, or a false-EMG biofeedback group. During the training sessions, significant frontalis EMG decreases were produced by the biofeedback group. This performance was associated with a concomitant decrease in heart rate and respiration rate, but an increase in skin conductance level. The biofeedback group was also able to maintain a low level of EMG activity during a stress-induction procedure. However, this low level of activity did not generalize to other physiological responses. Heart rate and skin conductance levels both increased, which coincided with the subjects' self-report of anxiety during this phase of the study. These data clearly demonstrate that single-system arousal reduction produced by EMG biofeedback training, rather than producing cross-system arousal reduction, produces specificity of a single response change under a stress-inducing situation.
