Temporomandibular Joint Disorders, Bruxism, Pain Threshold, Kinesiophobia
Conditions
Brief summary
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.
Interventions
PROCEDUREMuscle-energy mandibular technique
A single session will be used with the mandibular musculoenergy technique. It will last approximately 2-3 minutes and will be performed by a physiotherapist.
PROCEDURESham technique
A single session with a sham technique simulating the suboccipital muscle inhibition technique will be used. It will last approximately 2-3 minutes and will be performed by a physiotherapist.

DOUBLE (Subject, Outcomes Assessor)
Masking description
The participants will be blinded because in both groups they were following the treatment and medical recommendations and they will also be attended by a physiotherapist, in one case the mandibular muscular energy technique will be performed and in the other the placebo technique. The evaluators did not know to which group the participants belonged.

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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in craniofacial pain intensity | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | For the subjective evaluation of craniofacial pain, the visual analog scale (VAS) will be applied. Scale from 0 (no pain at all) to 10 (maximum possible pain). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in rightward mandibular translation | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | The active rightward mandibular translation will be measured using a digital caliper |
| Changes in leftward mandibular translation | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | The active leftward mandibular translation will be measured using a digital caliper |
| Changes in Pressure pain threshold at myofascial trigger point (PT1) of the both upper trapezius muscles | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | The pressure threshold will be recorded using a digital algometer |
| Changes in mouth opening mobility | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | The active opening of the mouth will be measured using a digital caliper |
| Changes in pressure pain threshold at myofascial trigger point of the both digastric muscles | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | The pressure threshold will be recorded using a digital algometer |
| Changes in kinesiophobia | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. And a follow-up after one week | The Kinesiophobia will be recorded using the spanish version of the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD-S). It is a valid and reliable instrument for measuring kinesiophobia in patients with TMD, and it uses a Likert scale (1-4) containing 11 items in 2 domains, with higher scores indicating higher levels of kinesiophobia (0-44). |
| Changes in pressure pain threshold at myofascial trigger point of the both external pterygoid muscles | 2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group. | The pressure threshold will be recorded using a digital algometer |
