Centering the person in development of a model of care for people with Parkinson's disease: a qualitative study.

Purpose: Obtain the perspectives of people with Parkinson's disease (PwPD) and their care partners (CPs) about their lived experiences with Parkinson's Disease (PD) to characterize a new model of care that meets their biopsychosocial and healthcare needs.

Methods: This phenomenological study included semi-structured focus groups exploring PD diagnosis/care experiences and conceptualizations of an ideal model of care among PwPD and CPs. Data were analyzed thematic analysis.

Acoustic Features of Transfeminine Voices and Perceptions of Voice Femininity.

The purpose of this study was to evaluate the relationships between acoustic measures of transfeminine voices and both self- and listener ratings of voice femininity. Connected speech samples were collected from 12 transfeminine individuals (M = 36.3 years, SD = 10.

Evidence-based treatment of voice and speech disorders in Parkinson disease.

Purpose Of Review: Voice and speech impairments are present in nearly 90% of people with Parkinson disease and negatively impact communication and quality of life. This review addresses the efficacy of Lee Silverman Voice Treatment (LSVT) LOUD to improve vocal loudness (as measured by vocal sound pressure level vocSPL) and functional communication in people with Parkinson disease. The underlying physiologic mechanisms of Parkinson disease associated with voice and speech changes and the strength of the current treatment evidence are discussed with recommendations for best clinical practice.

Intensive treatment of dysarthria secondary to stroke.

This study investigated the impact of a well-defined behavioral dysarthria treatment on acoustic and perceptual measures of speech in four adults with dysarthria secondary to stroke. A single-subject A-B-A experimental design was used to measure the effects of the Lee Silverman Voice Treatment (LSVT(®) LOUD) on the speech of individual participants. Dependent measures included vocal sound pressure level, phonatory stability, vowel space area, and listener ratings of speech, voice and intelligibility.

Intensive treatment of dysarthria in two adults with Down syndrome.

Objective: This study investigated the impact of an established behavioural dysarthria treatment on acoustic and perceptual measures of speech in two adults with Down syndrome (DS) and dysarthria to obtain preliminary measures of treatment effect, effect size and treatment feasibility.

Methods: A single-subject A-B-A experimental design was used to measure the effects of the Lee Silverman Voice treatment (LSVT®) on speech in two adults with DS and dysarthria. Dependent measures included vocal sound pressure level (dB SPL), phonatory stability and listener intelligibility scores.
