About

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.

Enrollment: 60 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients who agree to participate in the study by signing the informed consent form.
• Patients attending maxillofacial consultation with pain, temporomandibular dysfunction and bruxism.
• Pain of at least 3 months of evolution.

Exclusion criteria

• Patients with congenital malformations or cervical spine pathology.
• Infectious or inflammatory disease in its acute phase.
• Patients with vertigo or vestibular alterations.
• If there is a contraindication to the technique or phobia on the part of the patient.
• Physiotherapy treatment (manual therapy or electrotherapy) in the last month before their incorporation in the study.
• Pharmacological treatment (analgesics, relaxants and anti-inflammatory drugs) in the last 24 hours before the initial evaluation.

---

60 participants in 2 patient groups

Experimental Group (muscle-energy technique)

Experimental group

Description:

Mandibular muscle energy technique: In the supine position, the patient will open the mouth and perform isometric contractions for closure controlled by the physiotherapist. Passively, the physiotherapist will increase the range of mandibular opening. The technique consists of performing 3 sets, with 3 isometric contractions in each set of 3 seconds each. At the end of each set, the physiotherapist will passively try to gain mouth opening in order to continue the rest of the sets. At the end of all sets, gently return to the resting position.

Treatment:

Procedure: Muscle-energy mandibular technique

Control Group (sham technique)

Sham Comparator group

Description:

Sham technique: In the supine position, the physiotherapist will place his hands under the patient's skull with the fingertips in contact with the suboccipital musculature for 5 minutes, without applying pressure or therapeutic intent. The objective is to provide a stimulus as similar as possible to the original Suboccipital Inhibition Technique, but without force of movement. The patient will keep the eyes closed for the duration of the technique.

Treatment:

Procedure: Sham technique
