A Multidimensional Study on Articulation Deficits in Parkinsons Disease

United States40 participantsStarted 2021-09-09

Plain-language summary

Articulatory deficits are present in most speakers with dysarthria, which negatively impacts their speech intelligibility, yet little is known about the relationship between articulatory movement and speech intelligibility. This study will examine the relationship between articulation measures, both acoustic and kinematic, and their relationship to perceptual measures (i.e., speech intelligibility and articulation ratings) in 30 individuals with dysarthria secondary to Parkinson's disease and 30 neurologically healthy adults of the same age. The findings will have implications for behavioral management.
