Emg biofeedback ii: the dose-response relationship

36 clients with anxiety neurosis were trained to reduce frontalis muscle tension over two phases of ten sessions each. They were assessed on psychological and physiological measures, before, during and after the phases. The data analysis indicated that the clients succeeded in lowering frontalis muscle tension levels during the feedback and no-feedback phases of the training sessions. The inter-correlations among the outcome measures indicated that with an increasing amount of control of muscle tensior, the clients perceived greater amounts of change in state anxiety and in anxiety symptoms. This implies that EMG biofeedback can effect cognitive changes in clients.
