A Brief Biofeedback Training, Integrated with Breathing and Relaxation Exercises, in Treating Tinnitus Disorders within Routine Medical Care.

Tinnitus, a distressing condition, significantly impacts psycho-social functioning. While medical interventions have been the norm for treating tinnitus, few studies have explored the efficacy of psychological treatments and their enduring effects. This study aims to evaluate the effectiveness of a brief biofeedback training program in alleviating perceived tinnitus handicap severity over a 3-month follow-up period. Engaging 431 tinnitus outpatients from a medical center, the study allocated the control group to treatment as usual, involving monthly visits to an otolaryngologist and specific pharmacological interventions. Concurrently, the experimental group participated in a brief biofeedback training, using Procomp Infinity by Thought Technology Ltd., an eight-channel computer-operated encoder, integrated with breathing and relaxation exercises. No biofeedback booster sessions were provided to the experimental group during the 3-month follow-up period. Changes in tinnitus severity were assessed using the Tinnitus Handicap Inventory (THI). The analysis, conducted via ANCOVA, demonstrated that biofeedback, integrated with relaxation training and breathing exercises, had a positive impact on both the follow-up THI total score and its three sub-scales (Functional, Emotional, Catastrophic). Notably, the experimental group displayed reduced psycho-physiological parameters in all aspects compared to their baseline measurements at 3-month follow-up. This study's findings underline the effectiveness of non-pharmacological intervention in treating tinnitus. It had a positive impact on the emotional, functional, and physical dimensions of daily life affected by tinnitus.
