TL;DR
There is insufficient evidence to support or refute the efficacy of speech and language therapy for dysarthria in Parkinson's disease as intelligibility of speech was not measured in any of these studies.
Abstract
Considering the small number of patients examined, the methodological flaws in many of the studies, and the possibility of publication bias, there is insufficient evidence to support or refute the efficacy of speech and language therapy for dysarthria in Parkinson's disease. A Delphi-style survey is needed to develop a consensus as to what is 'standard' S< for dysarthria in Parkinson's disease. Then a large well designed placebo-controlled RCT is needed to demonstrate speech and language therapy's effectiveness for dysarthria in Parkinson's disease. The trial should conform to CONSORT guidelines. Outcome measures with particular relevance to patients should be chosen and the patients followed for at least 6 months to determine the duration of any improvement.
