Abstract:
Objective:To investigate the effect of Lee Silverman voice therapy (LSVT) on the speech and life quality of Chinese persons with Parkinson′s disease (PD).Methods:A total of 16 Chinese PD patients were enrolled and given standard LSVT for 4 weeks. Their acoustic data were analyzed using PRAAT software before and after the treatment. Their voice quality was evaluated using the Japanese GRBAS voice scale and their quality of life was quantified using the Voice Handicap Index (VHI) scale.Results:After 4 weeks of LSVT the patients′ average voice and life quality had improved significantly. The average maximum duration of sustained vowel phonation had increased significantly, as had the vowels′ mean loudness, reading and monologue delivery. The GRBAS grading indicated that hoarseness had decreased significantly. The average total voice handicap index had also decreased significantly.Conclusion:Lee Silverman therapy can significantly improve maximum phonation time and loudness of Chinese-speakers, which enhances sensory feedback. The quality of their speech and of their life also improve significantly. This technique is recommended for clinical application.
