Background: Tinnitus may have negative effects on the quality of life. Treatment of tinnitus has not yet shown satisfactory results, including non-pharmacological or pharmacological. Transcranial Direct Current Stimulation (tDCS) therapy has been developed and proven effective in the previous study. Purpose: To evaluate the correlation between tinnitus handicap inventory (THI) scores and tDCS therapy in tinnitus patients. Methods: The design was a prospective cohort study. The tinnitus patients were evaluated using THI in pre and post-treatment by tDCS therapy for 10 minutes on 5 consecutive days. The data was analyzed with the Pearson Correlation Test (p < 0,05). Result: There were 12 patients (3 female and 9 male) with a value of THI 53,83 in pre- treatment. The THI score was decreased to 40,83 in post-treatment. Pearson correlation test showed a correlation value of 0,977. This statistical analysis showed that there was a significant relationship between pre and post-tDCS therapy with Sig.
