Introduction The pathophysiology underlying postural instability in Parkinson's disease is
poorly understood. The frequent co-existence with freezing of gait raises the possibility of …

Freezing of gait (FOG) is a disabling feature of Parkinson's disease. Emerging evidence
suggests that dysfunction of the pedunculopontine nucleus (PPN) and pontomedullary …

Background It has been suggested that dynamical measures such as sample entropy may
be more appropriate than conventional measures when analyzing time series data such as …

This exploratory study aimed to identify which aspects of postural control are able to
distinguish between subgroups of patients with Parkinson's disease (PD) and controls …

Background: Freezing of gait in Parkinson's disease (PD) has been linked with deficits in
inhibitory control, but causal mechanisms are not established. Freezing at gait initiation (start …

Freezing of gait is a disabling symptom of Parkinson's disease that causes a paroxysmal
inability to generate effective stepping. The underlying pathophysiology has recently …

Postural instability and freezing of gait (FoG) are key features of Parkinson's disease (PD)
closely related to falls. Growing evidence suggests that co-existing postural deficits could …

Freezing of gait is a disabling symptom of Parkinson's disease (PD) that involves failure to
initiate and continue motor activity appropriately. PD disrupts fronto-basal ganglia circuitries …

Gait freezing and postural instability are disabling features of Parkinsonian disorders,
treatable with pedunculopontine nucleus stimulation. Both features are considered deficits of …

Background: People with Parkinson's disease and freezing of gait (FOG; freezers) suffer
from pronounced postural instability. However, the relationship between these phenomena …
