Feasibility of a Clinical Trial on Physiotherapy and Mouthguards for Bruxism Using Posture and EMG Analysis

The mouthguard and physiotherapy group will receive a custom-fitted mouthguard along with a physiotherapy program. The home-based physiotherapy exercises will include posture improvement routines, relaxation techniques, and targeted therapy for the muscles of the head, neck, and shoulders. These sessions will be performed daily at home for a duration of six weeks. Each participant will sign a consent form approved by the Ethics Committee of Saint Joseph University.

The mouthguard only group will receive a custom-fitted mouthguard, which will be fabricated by a qualified dentist. The mouthguard will be worn during sleep for 6 weeks. Participants will be instructed to clean the mouthguard daily and to store it in a cool, dry place.
