The effects of levodopa on word intelligibility in Parkinson's disease

Abstract
Dysarthria is a common manifestation in patients with idiopathic Parkinson's disease. This study investigated the effects of levodopa on intelligibility in patients with Parkinson's disease. Ten participants were tested during on- and off-states using the Yorkston and Beukelman intelligibility test (1980). Intelligibility as scored by a panel of speech therapists was significantly improved in the on-condition. No correlation was found, however, between intelligibility and overall severity of the disease or severity of the motor problems. EDUCATIONAL OUTCOMES: As a result of this activity the participant will be able to discuss the effects of levodopa on intelligibility in patients with Parkinson's disease.
