Temporomandibular joint dysfunction (TMD) is a multifactorial musculoskeletal disorder affecting the masticatory muscles, temporomandibular joint, and related structures, characterized by pain and functional limitations. In TMD, myofascial pain is particularly prominent, leading to decreased mandibular range of motion, impaired masticatory function, and reduced quality of life. Current literature shows that conservative treatment approaches, especially multimodal physiotherapy programs, are effective in reducing TMD symptoms. However, evidence regarding the clinical effectiveness of adding EMG-Biofeedback-based relaxation training, aimed at increasing awareness of muscle activity, to multimodal treatment programs is limited. The aim of this randomized controlled trial is to investigate the effect of EMG-Biofeedback-based relaxation training, added to a multimodal exercise program, on pain levels and functional parameters in individuals diagnosed with temporomandibular joint dysfunction. Participants will be divided into two groups using a simple randomization method. The control group will receive multimodal physiotherapy consisting of manual therapy and a home exercise program, while the experimental group will receive EMG-Biofeedback-based relaxation training in addition to the same program. Assessments will be conducted before the intervention and at the end of the 4-week intervention. Pain intensity will be measured with a Visual Analog Scale (VAS), pressure pain threshold with a digital algometer, mandibular joint range of motion with a linear scale, and cervical joint range of motion with a digital goniometer. Functional status will be assessed using the Fonseca Anamnestic Index, Neck Disability Index, and Oral Health Impact Profile-14. The obtained data will be compared using appropriate statistical analysis methods. This study is expected to provide scientific evidence regarding the clinical effectiveness of adding EMG-Biofeedback-based relaxation training to multimodal exercise programs in the conservative treatment of TMD and to contribute to filling the methodological gap mentioned in the literature.
