Is this trial a fit for you?

Likely a good fit

Adults with chronic subjective tinnitus for more than 6 months and a Tinnitus Handicap Inventory score of 18 or higher.

Probably not a fit

Individuals with objective tinnitus, unstable medical conditions, contraindications to TMS, or currently undergoing other tinnitus treatments during the study may be less likely to benefit.

What this trial studies

This is a randomized, placebo-controlled trial exploring three treatment arms over two weeks: 18 Hz deepTMS with the H1 coil, 1 Hz deepTMS with the H4 coil, and 18 Hz placebo deepTMS with the H7 coil. Participants will be adults with chronic subjective tinnitus and a moderate tinnitus burden who meet safety criteria, recruited primarily from Regensburg. After screening, 60 participants will be randomized in equal groups, with outcome assessments including standard audiological measures and tinnitus-related questionnaires. The study also references a historical matched control group treated with a conventional rTMS protocol for comparison. Primary goal is to see if active deepTMS reduces tinnitus distress more than placebo and how the different coils compare.

Why it matters

Potential benefit: If successful, patients may experience reduced tinnitus distress and improved quality of life.

How similar studies have gone: Prior deepTMS studies in tinnitus have shown variable outcomes; this trial adds head-to-head coil comparisons and a sham control.
