Scientific titlePriming stimulation as an enhancement of low-frequency repetitive Transcranial Magnetic Stimulation (rTMS) for the treatment of tinnitus
Study objectivesLow-frequency rTMS has been investigated for the treatment of hyperexcitability disorders such as auditory hallucinations and tinnitus. Experimental data indicate that the depressant effect of low-frequency rTMS can be enhanced by high frequency priming stimulation. In the proposed study we investigate whether priming improves therapeutic efficacy of low-frequency rTMS in a clinical application.
Ethics approval(s)Ethics Committee of the University of Regensburg, University Clinic Regensburg (ref: 01/194). Approved on 19.12.2001 (amendment on 19.2.2007).
Health condition(s) or problem(s) studiedChronic tinnitus
InterventionExperimental intervention: Low frequency rTMS over the left auditory cortex with priming stimulation: 6Hz (90% motor threshold, 960 stimuli) followed by low frequency rTMS (110% motor threshold, 1Hz, 1040 stimuli/day) 5 days a week for two weeks.
Control intervention: Standard protocol of low frequency rTMS (110% motor threshold, 1Hz, 2000 stimuli/day), 5 days a week for two weeks.
Intervention typeOther
Primary outcome measureChange in tinnitus severity according to the Tinnitus Questionnaire of Goebel and Hiller (baseline vs day 12).
Secondary outcome measuresReduction of tinnitus severity as measured by the Tinnitus Questionnaire of Goebel and Hiller (TQ; THI) during the follow-up period (screening versus baseline versus days 18, 59, 90).
