Within the limits of this study and with the reported assumption that the recorded EMG activity is related to bruxism, the results of this investigation suggest that the effect of biofeedback in reducing EMG activity is more consistent than an occlusal adjustment, possibly due to differences in the cause of the initial heightened EMG activity in the group of subjects studied.
