In Brief

A Phase 2 clinical trial evaluating rTMS for Subjective Tinnitus. Completed, enrolled 55 participants across 1 site.

Detailed Summary

The goal of this trial to see if repetitive transcranial magnetic stimulation (rTMS) to the hearing area of the brain can lessen the perception of tinnitus. rTMS uses a strong magnet and when placed against the scalp generates a small electrical field within the brain. Depending on the frequency of the stimulation, this electrical field can either decrease or increase the electrical excitability of the brain. In this study, low-frequency stimulation will be used, which is thought to decrease nerve activity. It is this electrical excitability of the brain that is thought to be responsible for tinnitus. The hypothesis of this study is that rTMS can decrease the perception of tinnitus.
