title: The effects of EMG biofeedback and relaxation training on primary dysmenorrhea.
abstract: Fifteen dysmenorrhea sufferers received relaxation training with EMG biofeeddback, relaxation training with no feedback, or no treatment. Participants who received biofeedback training did not differ from participants who received relaxation training in their ability to maintain a reduced level of EMG activity prior to the onset of menstruation. On the first day of menstruation, those receiving biofeeback training were able to maintain reduced EMG activity, whereas those receiving relaxation training showed an elevated level of EMG activity. Subjective reports indicated that the symptoms of dysmenorrhea improved for the biofeedback group during training but did not improve for the relaxation or control groups. Suggestions for further research are noted.
