Effects of Lee Silverman Voice Treatment (LSVT LOUD) on Swallowing in Patients with Progressive Supranuclear Palsy: A Pilot Study.
Article in Progress in rehabilitation medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesProgressive 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.
resultsAfter 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.
conclusionIn this small study, it was found that LSVT may improve swallowing functions in patients with PSP.
