Brief summary
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.
Interventions
PROCEDUREVisceral manual treatment
The patient will be placed in a reclining sitting position and triple flexion of the lower limbs to keep the abdominal region relaxed. The therapist will be placed to the right of the patient at the height of the abdomen, with the hands placed in the epigastric area. He will make a skin fold that reduces tension in the area, so that the contact is focused on the visceral tissue of the area. The patient will be asked to take deep breaths, and during the exhalation, the therapist will perform a zigzag movement with vibration of the hands while pulling the tissue caudally. This procedure will be performed for 5 minutes.
PROCEDURERespiratory listening
The patient and the therapist will be placed in the same position as in the experimental group. The therapist will place his hands in contact with the lower rib cage, and the patient will be asked to take a deep breath. The therapist will not exert any pressure, nor place restrictions on the tissues or movements of the ribcage.
