The purpose

Background: According to the International Association for the Study of Pain (IASP), the term temporomandibular disorder (TMD) regards a subgroup of orofacial pain, the symptoms of which include pain or discomfort in the temporomandibular joint, ears, masticatory muscles and neck on one or both sides as well as joint sounds, limited mandibular movements or mandibular deviation and difficulties chewing. Phototherapy, such as low level laser therapy (LLLT) and light-emitting diode (LED) therapy, is one of the resources used to treatment muscle pain. Thus, there is a need to investigate therapeutic resources that combine different wavelengths as well as different light sources (LLLT and LED) in the same apparatus. Question: The aim of the proposed study is to evaluate the effects of phototherapy on pain, activity of the masticatory muscles (masseter and anterior temporal bilaterally) and joint mobility in individuals with temporomandibular disorder (TMD). A further aim is to determine the cumulative effect 24 and 48 hours after a six session. Methods/Design: A placebo-controlled, double-blind, randomized, clinical trial will be carried out involving 30 women between 18 and 40 years of age with a diagnosis of myogenous TMD. The participants will then be randomly allocated to two groups totaling 15 individuals per group. Group 1 submitted to a session of phototherapy with 39,27 Joules per point one group will receive placebo therapy (0 Joules). The following assessment tools will be administered on four separate occasions (baseline and immediately after, 24 h after and 48 h after phototherapy). Pain intensity will be assessed using the visual analog scale for pain, meter for range of movement, and electromyographic EMG analysis on the masseter and anterior temporal muscles. Discussion: The study will support the practice of evidence-based to the use of phototherapy in individuals with a myogenous TMD. Data will be published after the study is completed.
