Study Protocol for a Single-blind Randomized Controlled Trial, Assessing the Specificity of an Alpha/Delta Ratio Neurofeedback Training Protocol in Chronic Tinnitus.

Philipps University Marburg·interventional·Posted Jun 8, 2018·Updated Mar 10, 2021

In Brief

A clinical study evaluating alpha/delta neurofeedback, beta/theta neurofeedback, and 1 other intervention for Tinnitus and 2 related conditions. Completed, enrolled 90 participants across 1 site.

Detailed Summary

This study will evaluate the efficacy of an alpha/delta ratio (ADR) neurofeedback training protocol on tinnitus distress. 1/3 of the participants in the study will undergo ADR neurofeedback training, 1/3 an active comparator, beta/theta ratio (BTR) neurofeedback training, whilst the final 1/3 of participants will fill in daily diaries of tinnitus complaints and symptoms for two weeks.

Interventions

alpha/delta neurofeedbackbehavioral

neurofeedback training protocol seeking to decrease the alpha/delta ratio, by simultaneous rewarding alpha and inhibiting delta activity.

beta/theta neurofeedbackbehavioral

neurofeedback training protocol seeking to decrease the beta/theta ratio, by simultaneous rewarding beta and inhibiting theta activity.

Diary completionother

completion of diary relating to participants' experience of tinnitus intensity, interference, coping, harm and disability. Rated three times daily on numerical scale (0 - 10) for two weeks.
