Study Summary

This trial is testing a possible new treatment for a type of tinnitus caused by neck movement.

What is being tested?
The study tests three treatments: physical therapy alone, sound-based therapy alone, and a combination of both. The goal is to see which method best alleviates somatosensory tinnitus—where symptoms are affected by certain movements.See study design
What are the potential side effects?
Potential side effects may include discomfort from physical therapy maneuvers or increased ringing during sound-based treatment. However, these therapies are generally considered low-risk.
