Clinical Trial Summary

Temporomandibular Disorder is a disorder that involves the muscles of mastication, the temporomandibular joint (TMJ), and associated structures. Convergence insufficiency (CI) is characterized by the inability of the eyes to perform the eye adduction movement together, to focus on a nearby object. Studies show that there is a relationship between the presence of TMD and its signs and symptoms in patients with convergence insufficiency. Given this, the research question of this clinical trial is whether the effect of oculomotor therapy would be effective in improving the signs and symptoms of Temporomandibular Disorder. The design of this research is a Clinical Trial, Randomized and Blind. It will be divided into two moments: evaluation and intervention. The evaluations will be carried out using the Diagnostic Criteria for Temporomandibular Disorders: Fonseca Anamnestic Index (IAF), Clinical Protocol and Assessment Instruments (DC/TMD), Mandibular function Impairment Questionnaire (MFIQ), Numerical Pain Scale (END), Convergence Test, Meersseman Test and Convergence insufficiency symptom Survey (CISS). Individuals will be randomized into 2 groups: Group A (Treatment for Temporomandibular Disorder) and Group B (Treatment Oculomotor plus Treatment for Temporomandibular Disorder). Both groups will receive physiotherapeutic treatment for 12 weeks. Patients will be reassessed shortly after treatment, 3 and 6 months later. For data analysis, the statistical significance considered will be p<0.05.
