Detection of passive movement in lower limb joints is impaired in individuals with Parkinson's disease.

Objective: Sensory information is crucial when performing daily activities, and Parkinson's disease may diminish sensitivity to sensory cues. This study aimed to examine the detection threshold of passive motion of knee and ankle joints in individuals with Parkinson's disease.

Methods: Eighteen individuals in the early stages of idiopathic Parkinson's disease (age: 62.

Parkinson's disease delays predictable visual cue processing without affecting complex and unpredictable visual cue processing in postural control.

This study examined the influence of visual information of different complexities and predictability on the body sway of individuals with Parkinson's disease (PD) during upright stance. Twenty-one individuals at initial stages of PD (62.1 ± 7.

People in early stages of Parkinson's disease are able to intentionally reweight the use of visual information for postural control.

Background: Parkinson's disease (PD) leads to several changes in motor control, many of them related to informational or cognitive overload. The aim of this study was to investigate the influence of knowledge and intention on the postural control performance and on the coupling between visual information and body sway in people with and without PD standing upright.

Methods: Participants were 21 people with PD (62.

Parkinson's disease does not alter automatic visual-motor coupling in postural control.

This study examined the coupling between visual information and body sway in patients with Parkinson's disease (PD) compared with healthy controls. Postural control performance was compared between 14 patients with PD (age: 69.6 ± 8.
