OBJECTIVES: To compare the outcomes of bi-weekly voice therapy (BWVT) with weekly voice therapy on perception, acoustics, and quality of life for individuals with muscle tension dysphonia (MTD).
METHODS: Thirty participants with MTD were enrolled either BWVT (40 min/session, two sessions per week for 4 weeks) or weekly voice therapy (40 min/session, once a week for 8 weeks). Auditory perceptual ratings, acoustic parameters, and the Mandarin version of the voice-related quality of life questionnaire (MV-RQOL) scores were statistically analyzed before and after treatment.
RESULTS: There were significant improvements in the voice qualities such as overall grade, roughness, asthenia, and strain in both groups after treatment. Acoustics analyses showed that fundamental frequency, speaking fundamental frequency, jitter, shimmer, and cepstral peak prominence significantly improved in both groups after treatment. For the MV-RQOL questionnaire scores, the result also demonstrated that both groups felt significant improvements in voice-related quality of life after treatment. However, there were no significant differences between the two groups of treatment effects.
CONCLUSIONS: Patients with MTD can restore voice qualities and quality of life if they are able to complete a full course of voice therapy, regardless of the intensity of voice therapy. However, if they can receive the BWVT, they would be able to regain their voice faster. The results of this study can be provided as a reference for clinicians when treating patients with MTD.
