Scientific Abstract
Tinnitus is a common condition that, for some individuals, is associated with significant psychological distress and impairments in daily functioning. Although various coping strategies and therapeutic approaches exist, no curative treatment is currently available.
Neurofeedback represents a promising yet underexplored therapeutic approach. Initial studies using an alpha/delta training protocol have reported positive effects on tinnitus distress and perceived loudness. However, their findings are limited due to small sample sizes and the absence of appropriate control conditions.
This research project aims to systematically investigate the effectiveness of neurophysiological interventions for distressing tinnitus. A randomized controlled trial with three study arms compares two neurofeedback protocols—alpha/delta ratio neurofeedback (ADR-NF) and beta/theta ratio neurofeedback (BTR-NF)—with a minimal intervention control group based on structured diary use. The goal of the study is to determine whether these interventions can reduce tinnitus-related distress and loudness. In addition, the project examines whether tinnitus is associated with impairments in executive attention processes. Alongside clinical and subjective outcomes, neurophysiological parameters are assessed to explore potential mechanisms of action and to contribute to a more robust evidence base for neurofeedback as a treatment option for chronic tinnitus.
