Clinical Trial 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.

Intervention

Procedure:
• Muscle-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.
• Sham 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in craniofacial pain intensity	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).	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in mouth opening mobility	The active opening of the mouth will be measured using a digital caliper	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in rightward mandibular translation	The active rightward mandibular translation will be measured using a digital caliper	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in leftward mandibular translation	The active leftward mandibular translation will be measured using a digital caliper	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in Pressure pain threshold at myofascial trigger point (PT1) of the both upper trapezius muscles	The pressure threshold will be recorded using a digital algometer	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in pressure pain threshold at myofascial trigger point of the both external pterygoid muscles	The pressure threshold will be recorded using a digital algometer	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in pressure pain threshold at myofascial trigger point of the both digastric muscles	The pressure threshold will be recorded using a digital algometer	2 evaluations, one pre-intervention and one post-intervention, 5 minutes after the end of the intervention according to the assigned group.
Secondary	Changes in kinesiophobia	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).	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
