Key result
EMG biofeedback training produced significant frontalis EMG decreases during training and stress-induction, but did not produce cross-system arousal reduction.

Does EMG biofeedback reduce multiple system physiological arousal during training and stress-induction conditions in subjects?
EMG biofeedback training produces specific single-system arousal reduction rather than generalized cross-system arousal reduction under stress-inducing situations.
Gatchel et al. (1978) reported an RCT. EMG biofeedback vs. false-EMG biofeedback was evaluated on multiple system physiological responding (frontalis EMG, heart rate, respiration rate, skin conductance). EMG biofeedback training produced significant frontalis EMG decreases during training and stress-induction, but did not produce cross-system arousal reduction.
