BACKGROUND AND PURPOSE: Postural instability gait disorder is a motor subtype of
Parkinson disease associated with predominant gait dysfunction. We investigated the …

Background There have been no previous diffusion tensor imaging (DTI) studies comparing
Parkinson's disease (PD) with postural instability and gait disorder (PIGD) parkinsonism …

Objectives This study applies diffusion tensor imaging (DTI) to determine differences in
neuronal integrity between motor phenotypes in Parkinson's disease. Material and Methods …

Background: Patients with the postural instability and gait difficulty (PIGD) subtype of
Parkinson disease (PD) are at a higher risk of dysfunction and are less responsive to …

Introduction The postural instability gait difficulty motor subtype of patients with Parkinson's
disease (PIGD-PD) has been associated with more severe cognitive pathology and a higher …

Background Gait impairments are common in Parkinson's Disease (PD) and are likely
caused by degeneration in multiple brain circuits, including the basal ganglia, thalamus and …

Background: Freezing of gait is a common and disabling symptom of parkinsonism.
However, the corresponding anatomic structures have yet to be clearly elucidated. Methods …

Background Periventricular leukoaraiosis may be an important pathological change in
postural instability gait disorder (PIGD), a motor subtype of Parkinson's disease (PD) …

Objective: We quantitatively evaluated the gait of Parkinson's disease (PD) patients over a
10-m course during normal walking and during dual-task walking while performing a …

Background Gait abnormalities in the elderly, characterized by short steps and frozen gait,
can be caused by several diseases, including idiopathic normal pressure hydrocephalus …
