Impact of Pallidotomy on Physiological Articulation Function and Speech Intelligibility in Parkinson Disease.

Impact of Pallidotomy on Physiological Articulation Function and Speech Intelligibility in Parkinson Disease.

The objective of this study was to evaluate the effects of posteroventral pallidotomy on perceptual and physiological measures of articulatory function and speech intelligibility in Parkinson disease (PD). The study examined 11 participants with PD who under-went posteroventral pallidotomy. Physiological measures of lip and tongue function and perceptual measures of speech intelligibility were obtained prepallidotomy […]

Language Production by Patients with Parkinson Disease Before and After Unilateral Posteroventral Pallidotomy (Report)

Language Production by Patients with Parkinson Disease Before and After Unilateral Posteroventral Pallidotomy (Report)

Measures of language production (e.g., informativeness, cohesion) could further our understanding of the cognitive-linguistic abilities of patients with Parkinson’s disease (PD) and guide treatment focused on improving the overall communication ability. The current study measured correct information units (CIUs), total words, cohesion markers, content units (CUs), interpretive (CUis), and lexical efficiency in narrative (i.e., Cookie […]

Reliability of Speech Intelligibility Ratings Using the Unified Parkinson Disease Rating Scale.

Reliability of Speech Intelligibility Ratings Using the Unified Parkinson Disease Rating Scale.

The Unified Parkinson Disease Rating Scale (UPDRS) is widely used by medical, nursing, and allied-health professionals in the management and study of patients with Parkinson disease (PD), who sometimes present with decreased speech intelligibility. As such, examining the reliability of speech intelligibility ratings using the UPDRS is critical in evaluating its utility as an instrument […]
