Mandibular Muscle Energy Technique in Patients With Mandibular Joint Pathology and Bruxism

This is a randomized, controlled, double-blind clinical trial. The main objective is to evaluate the immediate effect of the mandibular muscle-energy technique on pain, functionality and kinesiophobia in subjects suffering from temporomandibular dysfunction and bruxism. In the experimental group the jaw muscle-energy technique will be applied and in the control group a placebo technique will be applied. The intention is to see the immediate effects of the intervention and two evaluations of the pre- and post-intervention outcome variables and a follow-up of kinesiophobia one week later will be performed.
