NCT07740954

Brief Summary

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.

Study Arms (3)

Manual Therapy,

EXPERIMENTAL

Participants assigned to this group will receive manual therapy targeting the cervical spine and temporomandibular region. Treatment will include soft tissue mobilization, trigger point release, joint mobilization, stretching, and other manual techniques as indicated. Participants will receive 12 treatment sessions over a 6-week period.

Behavioral: Manuel therapy

Tinnitus Retraining Therapy

ACTIVE COMPARATOR

Participants assigned to this group will receive Tinnitus Retraining Therapy (TRT), consisting of directive counseling and individualized sound therapy. The intervention will be delivered over 12 sessions during a 6-week treatment period.

Behavioral: Manuel therapy

Combined Manual Therapy and Tinnitus Retraining Therapy

ACTIVE COMPARATOR

Participants assigned to this group will receive both manual therapy and Tinnitus Retraining Therapy (TRT). Manual therapy will target the cervical spine and temporomandibular region, while TRT will consist of directive counseling and individualized sound therapy. Participants will receive 12 treatment sessions over a 6-week period.

Behavioral: Manuel therapy

This 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.
