ABSTRACT:
Apparatus for producing an electrical stimulation signal adapted to be applied to a patient's jaw muscle, thereby causing the jaw to open and preventing bruxism. The apparatus includes electrodes positioned to sense an electromyographic (EMG) signal indicative of jaw muscle activity and jaw clenching. A control circuit produces a control signal when the EMG signal exceeds a threshold value indicative of a predetermined level of jaw muscle activity. Stimulator means produce the stimulation signal in the form of a pulse train when triggered by the control signal. The threshold value and intensity of the stimulation signal are adjustable.
