Efficacy of Manual Therapy in the Treatment of Somatic Tinnitus

Efficacy of Manual Therapy in the Treatment of Somatic Tinnitus: A Randomised Controlled Trial

Somatic tinnitus is an unpleasant perception of sound that occurs in the absence of any external acoustic stimulus. Despite the correct diagnosis of somatic tinnitus, there is currently no specific treatment. The hypothesis of this study is that the application of manual therapy to the cervical region will help to treat tinnitus in patients. This study aims to investigate the effectiveness of manual therapy in the treatment of somatic tinnitus of cervicogenic origin.

Somatic tinnitus is an unpleasant perception of sound that occurs in the absence of any external acoustic stimulus. It results from complex interactions between the somatosensory and auditory systems, which involve the musculoskeletal system rather than the ear. The temporomandibular joint, craniocervical junction, cervical vertebrae and neck and shoulder muscles, in particular the sternocleidomastoid (SCM) muscle, upper trapezius and levator scapula, are anatomical regions that can cause somatic tinnitus.

Despite the correct diagnosis of somatic tinnitus, there is currently no specific treatment. The hypothesis of this study is that the application of manual therapy to the cervical region will help to treat tinnitus in patients. This study aims to investigate the effectiveness of manual therapy in the treatment of somatic tinnitus of cervicogenic origin.
