It is unclear how bracing and thrusting may contribute to potential musculoskeletal symptoms associated with bruxism.OBJECTIVE: To examine the effect of experimental bracing and thrusting of the mandible on the development of musculoskeletal symptoms in healthy volunteers.METHODS: Thirty healthy volunteers performed six trials of 5 min of repeated bracing and thrusting of the mandible.
