From: Falling Direction can Predict the Mechanism of Recurrent Falls in Advanced Parkinson’s Disease
Scheme of the mechanism and characteristics of PD forward fallers and non-forward fallers. Falling forward was related to freezing of gait, while balance impairment, akinetic-rigid subtype, and neuropsychiatric symptoms were associated with falling backwards or sideways. In terms of falling situations, forward fallers tended to fall during walking and turning, while non-forward fallers mainly fell during walking and sitting/standing. Additionally, non-forward fallers had more frequent mild falls, and less moderate falls compared with forward fallers.
