Effects of Lee Silverman Voice Treatment (LSVT LOUD) on Swallowing in Patients with Progressive Supranuclear Palsy: A Pilot Study
OBJECTIVES: Progressive supranuclear palsy (PSP) is an uncommon progressive neurodegenerative disease with no effective cure at present. The initial symptoms resemble those of Parkinson’s disease; however, the prevalence of PSP is about one-tenth that of Parkinson’s disease. In many cases, dysphagia...

description | OBJECTIVES: Progressive supranuclear palsy (PSP) is an uncommon progressive neurodegenerative disease with no effective cure at present. The initial symptoms resemble those of Parkinson’s disease; however, the prevalence of PSP is about one-tenth that of Parkinson’s disease. In many cases, dysphagia is severe, and the development of dysphagia is an early predictor of life expectancy. The aim of the current study was to define the effects of Lee Silverman Voice Treatment (LSVT LOUD) on swallowing and voice/speech in seven patients with PSP. METHODS: : Each patient underwent swallowing and voice/speech evaluations before and after 4 weeks of LSVT. Swallowing motility disorders were defined, temporal measures of swallowing were determined by videofluoroscopic evaluation, and voice measures of maximum phonation and speech intelligibility in reading and monologue were examined. RESULTS: After LSVT, the median duration of opening of the upper esophageal sphincter (from the beginning of the posterior movement of the bolus to upper esophageal sphincter opening) on videofluoroscopy was significantly shortened from 0.42 to 0.38 s (Wilcoxon signed-rank test P=0.016). The oral transit duration was decreased in five patients, but the decrease was not significant. Voice changes after LSVT included increases in voice intensity and in sustained duration were not significant. CONCLUSION: In this small study, it was found that LSVT may improve swallowing functions in patients with PSP. |
