Objective: In this study, the effectiveness of abdominal (diaphragm) respiratory training on muscle tension dysphonia was investigated using aerodynamic parameters.

Material-Method: 60 patients between the ages of 18-65 who were diagnosed with muscle tension dysphonia were included in the study. 60 healthy individuals were included in the control group. Maximum phonation time (/ a /), maximum (/ s /)duration, maximum (/ z /) duration, s / z ratio, vital capacity and phonification quotient were measured before respiratory training for all participants. Abdominal (diaphragm) respiratory training was given to the group with muscle tension dysphonia, and aerodynamic parameters were measured again after 4 weeks of respiratory training. The data of the control group were compared with the data of the patient group before abdominal (diaphragm) respiratory training. Then, the patient group"s aerodynamic parameters before the abdominal respiratory training were compared with the patient group"s aerodynamic parameters after the training.

Results: The aerodynamic parameters of patients before abdominal (diaphragm) respiratory training; maximum phonation time, vital capacity, s / z ratio and phonation quotient were found to differ statistically significantly from the control group (p <0.05). When the patient data after four weeks of respiratory training were compared with the patient data before respiratory training, no significant change was observed in the other parameters (p <0.05), except for the s / z ratio (p <0.05).

Conclusion: The main source of sound is air in the lungs. Therefore, correct and effective breathing is necessary for the effectiveness and continuity of phonation. Although, in our study, no statistically significant change was observed in relation to aerodynamic parameters, vital capacity, maximum phonation time and phonification quotient after 4 weeks, positive changes were observed in all the parameters mentioned. While it was thought that the four-week period might be short, it was observed that abdominal (diaphragm) respiratory training was effective on the s / z ratio of aerodynamic parameters.
