Fig. 1. Global improvement (GI) index and change in Visual Analogue Scale (VAS) of tinnitus loudness (10-point), tinnitus awareness score (TAS, %), and Tinnitus Handicap Inventory (THI) score immediately after the end of the 10th session. Of the 30 patients, 15 patients reported an improvement in symptom (grade 5 and 6), 13 patients reported no change (grade 4), and 2 patients reported mild worsening of symptoms (grade 3). In 16/25 patients (64.0%), the VAS of tinnitus loudness decreased (i.e., improved), five patients (20.0%) reported no change in subjective loudness and 4 patients (16.0%) reported an increase in loudness. The tinnitus awareness score decreased (i.e., improved) in 13/25 patients (52.0%), was unchanged in 8/25 patients (32.0%), and increased in 4/25 patients (16.0%). The THI score decreased from baseline to after treatment in 11/24 patients (45.8%), was unchanged in 3 patients (12.5%), and worsened in 10 patients (41.7%).
