Pivotal Psoriasis Study

Researchers are preparing to directly compare three treatment approaches for a specific form of tinnitus. A new randomized controlled trial, identified as NCT07740954, will test Manual Therapy, Tinnitus Retraining Therapy, and a combination of both in 65 adults with somatosensory tinnitus. The results could clarify whether physical and neurological approaches should work separately or in concert for patients whose head and neck movements trigger their symptoms.

What the Trial Will Test: A Direct Comparison of Three Approaches

This interventional study has a clear design. Sixty-five participants will be randomly assigned to one of three parallel groups. The first group will receive Manual Therapy, a hands-on physical treatment focused on the cervical spine and muscles. The second group will undergo Tinnitus Retraining Therapy, a structured program of counseling and sound therapy designed to reduce the brain’s reaction to tinnitus. The third group will receive a combination of both treatments.

The intervention period lasts six weeks. Researchers will measure a wide range of outcomes before and immediately after treatment. These include the primary measures of tinnitus severity and tinnitus-related disability. Secondary outcomes cover neck disability, cervical range of motion, standard audiological measures, pressure pain threshold, and scores for anxiety, depression, and quality of life.

Targeting a Specific Tinnitus Mechanism: The Somatosensory Subtype

The trial focuses specifically on chronic subjective somatosensory tinnitus. This diagnosis applies to individuals whose perceived sound can be altered by physical maneuvers. For these patients, clenching the jaw, turning the head, or pressing on neck muscles can change the tinnitus pitch or loudness. This link suggests a neurological crossover between the pathways for sound and somatic sensation in the head and neck.

Manual Therapy aims to address potential musculoskeletal dysfunctions in this area. Tinnitus Retraining Therapy, developed by Pawel Jastreboff, targets the maladaptive emotional and auditory processing of the sound. The combined therapy investigates whether addressing both the potential physical trigger and the brain’s reaction simultaneously yields a stronger effect.

Who Can Participate in This Study

The study has specific criteria to isolate the somatosensory subtype. Inclusion requires adults aged 18 to 65 with a chronic tinnitus diagnosis lasting at least three months. A key requirement is that the tinnitus must be modifiable by head, neck, jaw, or temporomandibular movements or by muscle palpation. Participants must have normal middle ear function and commit to the full schedule of treatments and assessments.

Several conditions will exclude potential participants. These include objective or pulsatile tinnitus, a duration under three months, and diagnoses like Ménière’s disease, otosclerosis, or vestibular schwannoma. Active middle ear disease or abnormal immittance results also preclude participation.

Current Status and Potential Impact for Patients

The trial’s status is listed as NOT_YET_RECRUITING. The research team is finalizing logistics before opening enrollment for the target of 65 participants.

For the field of hearing health, this trial addresses a common question in tinnitus management: which treatment, for which patient? By directly comparing two established but distinct approaches and their combination, the study aims to generate evidence for more precise clinical decisions. If one approach proves superior, or if the combined therapy shows clear added benefit, it would support more effective and efficient treatment protocols. For patients with somatosensory tinnitus, the findings could point toward more targeted and potentially more successful strategies to reduce the burden of their condition.
