The reduction of bruxism using contingent EMG audible biofeedback: a case study

This report describes the use of EMG biofeedback to reduce bruxism in an 18-year-old woman. The behaviour was severe and not responsive to standard dental treatment. In addition to psychometric measures of affective status, objective measures of both the frequency and intensity of bruxing incidents were made, and a 4-week intervention conducted. On the bruxing and affective measures significant improvements were noted, as were reductions in associated pain and dysfunction.
