SUMMARY:

Tinnitus is the perception of sound in the absence of an external sound source, its impact on quality of life can range from slight to catastrophic. Currently, there are several possibilities for tinnitus management, among them is neuromodulation. Transcranial Direct Current Stimulation (tDCS) is a painless and non-invasive neuromodulation technique that uses a low-intensity electrical current to stimulate or inhibit the central nervous system in order to normalize neuronal activity and alleviate tinnitus. Purpose: (1) to verify if there is a change in the annoyance and impact of tinnitus after tDCS in patients with chronic tinnitus. (2) to investigate the applicability and effectiveness of Transcranial Direct Current Stimulation as a therapeutic resource in individuals with chronic tinnitus complaints. Method: (1) pilot study designed as an uncontrolled clinical trial. (2) study designed as a randomized controlled clinical trial. Approved by the Research Ethics Committee of the Hospital Universitário Onofre Lopes (HUOL), opinion nº 5.622.441 and by ReBEC, nº RBR-109xh8d6. The sample consisted of adult patients referred from the Tinnitus clinic at HUOL, of both genders, with a current complaint of chronic tinnitus, after basic audiological evaluation. Patients who fit the contraindications to the use of neuromodulation were excluded. Anamnesis, high-frequency audiometry and, to characterize the outcome measures, acuphenometry, the Visual Analog Scale (VAS) and the Tinnitus Handicap Inventory (THI) questionnaire were performed. The intervention protocol consisted of applying a current of 2mA, for 20 minutes, with an anodic electrode in the left temporoparietal cortex and a cathodic electrode in the right dorsolateral prefrontal cortex, in five consecutive sessions (1), and during ten alternating sessions (2). The results were analyzed descriptively (1) and the preliminary data (2) submitted to inferential statistical analysis. Results: (1) Three female and two male patients were evaluated; average age of 45 years, hearing within normal ranges and decreased hearing sensitivity at high frequencies. After the five neuromodulation sessions, the mean total score on the THI ranged from 36.8 to 33.2 points and, on the VAS, it ranged from 5.16 to 4.4 points. (2) So far, the sample consisted of 17 patients (ten in the experimental group (EG) and seven in the control group (CG)), with a mean age of 49 years. The total average on the VAS reduced from 4.8 to 4.3 points (p= 0.17). There was a reduction in the scores of all THI subscales after neuromodulation, with a significant difference (p= 0.001) for the total score (38 to 28 points). There was also a significant difference (p= 0.0005) in the total THI score, in the comparison between the EG and GC after neuromodulation. Final considerations: (1) There was a decrease in the perception of tinnitus annoyance and damage after the neuromodulation sessions. (2) So far, there was a significant decrease in the perception of the impact of tinnitus on quality of life after the intervention through tDCS, in the experimental group and in the comparison between groups.
