Objective: check the effectiveness of visceral manual therapy on bruxist patients Design: Experimental, analytical, longitudinal, prospective, randomized, single-blind study with a blinded evaluator. Subjects: 68 subjects over 18 years old, with bruxism (diagnoses by a dentist). Methods: Subjects will be randomized into 2 groups: an experimental group (EG) to which a visceral manual technique will be applied and a control group (CG) to which a placebo manual technique will be administered. Both groups will receive 2 interventions one week apart. The measurements will be made before and after the interventions, and a last measurement will be made one month after the last intervention. Therefore, the patient will visit the center 3 times.
