About this trial
This randomized clinical trial aims to evaluate the effectiveness of photobiomodulation therapy (PBM) alone or combined with therapeutic exercises compared with placebo PBM associated with exercises in patients with myofascial temporomandibular disorders (TMD). Participants will be allocated into three groups: PBM alone, PBM combined with exercises, or placebo PBM combined with exercises. The intervention consists of 12 treatment sessions. Outcomes related to pain intensity, mandibular function, and clinical measures will be assessed over time. The study seeks to investigate whether PBM provides additional benefits in pain reduction and functional improvement in individuals with myofascial TMD.
