Influence of Treatment Duration and Stimulation Frequency on rTMS in Chronic Tinnitus

Summary

Patients receive two weeks of treatment (prefrontal high-frequency and bilateral low-frequency rTMS vs. prefrontal high-frequency and bilateral high-frequency rTMS). After two weeks of treatment they can decide if they want to quit the treatment or if they want to proceed with the treatment for another two weeks.

Conditions

• Chronic Tinnitus

Interventions

OTHER

standard multisite four weeks

Repetitive transcranial magnetic stimulation (Magventure): 1000 stimuli of 20 Hz rTMS over the left DLPFC (110% motor threshold) followed by 1000 stimuli of 1 Hz rTMS over the left temporoparietal cortex (110% motor threshold) followed by 1000 stimuli of 1 Hz rTMS over right temporoparietal cortex (110% motor threshold). Patients continue treatment after two weeks for further two weeks of treatment (20 treatment days).
