Combined Transcranial and Peripheral Muscle Magnetic Stimulation in Chronic Tinnitus

Not Applicable

Completed

• Conditions: Chronic Tinnitus
• Interventions: Device: rPMS and rTMS

• Registration Number: NCT02306447
• Lead Sponsor: University of Regensburg

Brief Summary

Magnetic stimulation of the brain (repetitive transcranial magnetic stimulation) and of neck muscles (repetitive peripheral muscle stimulation) is used to alter tinnitus-related cortical activity and neck muscles tension.

Detailed Description

Chronic tinnitus is characterized by several comorbid disorders. One of them is neck and back pain. Here, we investigate the feasibility, safety and clinical efficacy of the combination of repetitive transcranial magnetic stimulation (rTMS) and peripheral muscle stimulation (rPMS) in chronic tinnitus in a pilot study. rTMS is considered to interact with neural tinnitus networks. rPMS is suggested to bring relief to muscle tension. This is an one arm study where explorative analyses will be done with special consideration on patients suffering from neck pain in the analysis.

Arm && Interventions

Group	Intervention	Description
rPMS and rTMS	rPMS and rTMS	rPMS Stimulation of the neck muscles in five medial-lateral movements starting from the neck: left and right trapezius and deltoid muscle, trapezius and lattissimus dorsi muslce, and over the backbone. 20 stimuli per movement with 2s inter-train interval; four repetitions for each of the five movements; the first 20 trains with a frequency of 5Hz, the second 20 trains at 20Hz; stimulation at individual comfortable level (20-30% stimulator output); round coil. rTMS 20Hz stimulation with 2000 stimuli over the left dorso-lateral prefrontal cortex at 110% motor threshold; followed by 1Hz stimulation with 2000 stimuli over the left temporo-parietal cortex; stimulation intensity 110% motor threshold; butterfly coil. For stimulation we use MagPro X100 (Medtronic, Denmark).
