Treatment of dysarthria in Parkinson disease

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Voice and speech disorders occur in up to 89% of people with Parkinson disease (PD). The most common perceptual characteristics include reduced vocal loudness, monotone, hoarse or breathy voice quality, and imprecise articulation. The Lee Silverman Voice Treatment (LSVT LOUD®) is an effective speech therapy to improve vocal loudness and functional communication in people with PD. This case study will illustrate classic voice and speech symptoms in a person with moderate PD and the positive outcomes following LSVT LOUD treatment. The rationale and efficacy data of this treatment approach will be discussed.
