Study on the Treatment of Tinnitus with Personalized Brainwave Training (Neurofeedback)
Zusammenfassung der Studie
This study investigates whether a specific training with brainwaves (neurofeedback) can alleviate the complaints of people with persistent ear noise (tinnitus). Participants will attend several sessions over approximately nine months, during which brain activity will be measured using a special cap. Through visual feedback on a screen, participants learn to intentionally influence their brainwaves. A total of 20 training sessions and 5 measurements are planned. The study is designed so that participants receive both active training and a placebo treatment. Neither the participants nor the examiners know which treatment is administered at which time, corresponding to a random assignment like a coin toss. Additionally, hearing tests will be conducted, and questionnaires regarding well-being and tinnitus experience will be used. All procedures are safe and non-invasive. Mild, temporary side effects such as fatigue or headaches may very rarely occur after the sessions. The results of the study aim to contribute to improving the treatment of tinnitus in the future.

Untersuchte Intervention
The intervention studied in this research is a personalized neurofeedback therapy (NFB). This is a non-invasive training procedure aimed at the targeted alteration of brain activity patterns associated with chronic tinnitus. An EEG system (BrainProducts actiChamp) with 64 electrodes is used to measure the participants' brainwaves in real-time. A specially developed software analyzes this data and identifies individual, tinnitus-relevant features in the EEG for each participant using machine learning. These personalized features serve as the basis for the training. During the sessions, participants receive visual feedback of their brain activity on a screen, usually in the form of an animation. The goal is for participants to learn to voluntarily control their brainwaves in such a way that the tinnitus-associated patterns normalize. A training session lasts about 15 minutes. The entire study also includes a control condition with a placebo treatment (placebo neurofeedback) to verify the specific effectiveness of the training. The study is conducted in a double-blind manner, so neither participants nor examiners know which treatment is administered.
