Abstract
This study compared the efficacy of two treatment modalities (stress-reduction behavioral counseling and contingent nocturnal EMG biofeedback) on night-time bruxism. The 16 subjects (Ss) were assigned sequentially to one of four treatment groups: (1) stress-reduction behavioral counseling: (2) nocturnal biofeedback; (3) stress-reduction behavioral counseling and nocturnal biofeedback; and (4) waiting-list control group. A portable EMG unit was used to record the nightly total of electrical activity (≥20 μV) from the masseter muscle 10 days before and after treatment. The three treatment procedures were found to be significantly superior to no-treatment control group. The outcome of the two treatments which made use of stress-reduction behavioral counseling, although better than the treatment which solely used nocturnal biofeedback, was not significantly better. This study demonstrates that stress-reduction skills learned while awake can have a generalized effect on stress-induced muscle activity during sleep. Implications for further research are discussed.
