About this trial
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.

BehavioralThis study is a prospective, single-center, assessor-blinded, three-arm, parallel-group randomized controlled trial designed to compare the effectiveness of Tinnitus Retraining Therapy (TRT), Manual Therapy (MT), and the combination of TRT plus MT in adults with somatosensory tinnitus. Participants will be randomly assigned in a 1:1:1 ratio using a computer-generated block randomization sequence. Allocation concealment will be ensured using the sequence.
