Emg biofeedback I: treatment outcome in anxiety neurosis.

36 subjects were included in a study on the efficacy of EMC biofeedback training in the management of anxiety neurosis. The outcome measures included a physiological stress profile and measures of anxiety symptoms, frontalis muscle tension, skin temperature and electrodermal activity. The data analysis indicated that the subjects were able to maintain reduced levels of frontalis muscle tension at rest and during the stress condition without concomitant changes in skin temperature or in electrodermal activity. This pattern of results supported the prediction of the motor skills learning model of EMG biofeedback. The clinical benefits of the training were manifested in the decreased anxiety symptom scores.
