Title: Comparative study of high-power and low-power laser therapy in the treatment of tinnitus Objectives: To determine the efficacy of high-power and low-power laser therapy in reducing the loudness of chronic tinnitus and improving the quality of life in patients suffering from chronic tinnitus. Additionally, to compare the effects of both types of lasers. Methods: A total of 18 subjects were included in the experiment, who underwent an otorhinolaryngological, neurological, and kinesiological examination by a physiotherapist. The TSCHQ questionnaire was used to collect data, including the scaling of tinnitus loudness. Quality of life was assessed using the THI questionnaire. To determine the effect, data obtained from the questionnaires before and after intervention were compared. Descriptive statistics and non-parametric tests were used for statistical analysis. The homogeneity of groups was compared using the Mann-Whitney test, the Wilcoxon test was used to compare the effect of the laser within one group. The Chi-square test was used to evaluate qualitative data. The level of significance was set at 5 % (α = 0.05). Results: It was found that HILT had a statistically significant positive effect on reducing the intensity of chronic tinnitus, while LLLT did not. Therefore, high-power laser is...
