This randomized controlled trial aims to compare the effectiveness of Manual Therapy (MT), Tinnitus Retraining Therapy (TRT), and their combination in adults with somatosensory tinnitus. Sixty-five participants will be randomly assigned to one of three parallel groups. Primary and secondary outcomes include tinnitus severity, tinnitus-related disability, neck disability, cervical range of motion, audiological measures, pressure pain threshold, anxiety, depression, and quality of life. Outcomes will be assessed before treatment and immediately after the six-week intervention period.
