BACKGROUND: Movement disorders are a group of neurological motor disturbances
manifested by either paucity or slowness of movement, such as seen in Parkinson's disease …

Respiratory dysfunction has been associated with Parkinson's disease since it was first
described in 1817. The respiratory symptoms observed in Parkinson's disease patients vary …

Background: Parkinson's disease (PD) is a progressive neurodegenerativa disorder where
patients exhibit impairments in speech production. Few studies have investigated the …

Objective: To evaluate the exercise capacity of subjects with mild to moderate Parkinson's
disease and determine whether abnormalities in respiratory function and gait affect exercise …

Multiple investigations have determined that healthy adults swallow most often during
exhalation and that exhalation regularly follows the swallow, even when a swallow occurs …

Introduction In Parkinson's disease (PD), respiratory insufficiency (including functional and
muscle disorders) can impact dysarthria and swallowing. Most studies of this topic have …

The purpose of this study was to determine if individuals with Parkinson's disease (PD)
demonstrate abnormal respiratory events when swallowing thin liquids. In addition, this …

There has been increasing recognition of pre-motor manifestations of Parkinson's disease
(PD) resulting from early brainstem involvement. We sought to determine whether ventilatory …

The purpose of this study was to:(1) define perceptual speech characteristics of idiopathic
Parkinson disease (IPD) across 35 speech dimensions adapted from Darley et al.[19] and …

In contrast to some other neurodegenerative diseases, little is known about ventilatory
dysfunction in Parkinson's disease (PD). To assess the spectrum of ventilation disorders in …
