Peering through the FoG: visual manipulations shed light on freezing of gait.

摘要: Freezing of gait (FoG) – the intermittent and usually brief interruption forward progression despite intention to walk is poorly understood, in part because its episodic unpredictable nature makes it notoriously difficult study laboratory.1, 2 This issue Movement Disorders includes descriptions two promising new methods for eliciting quantifying FoG or slowing that may be a precursor people with Parkinson’s disease (PD). Both exploit known association visual stimuli, most classically precipitation by doorways narrow spaces.3
