The relationship between motor planning and freezing of gait in Parkinson's disease

ObjectiveTo examine how a cued change in motor plan influences Parkinson's disease (PD) patients with freezing of gait (FOG) (PD FOG; n=10), compared with those without FOG (PD non-FOG; n=10) and healthy controls (n=10).MethodsParticipants walked through a doorway in three experimental conditio...

Zusammenfassung:	ObjectiveTo examine how a cued change in motor plan influences Parkinson's disease (PD) patients with freezing of gait (FOG) (PD FOG; n=10), compared with those without FOG (PD non-FOG; n=10) and healthy controls (n=10).MethodsParticipants walked through a doorway in three experimental conditions: no cue; cue before gait initiation; and cue after gait initiation. The light cue was presented at the end of the pathway and signified that individuals must walk to the cue, turn around and return to starting position.ResultsStep-to-step variability (a known precursor to FOG) revealed a significant main effect of group (F2,27=32.83, p
