Increased foot strike variability during turning in Parkinson's disease patients with freezing of gait.

ABSTRACT:

Background

Turning is a common trigger for freezing episodes in patients with Parkinson's disease (PD). Freezing during turning can lead to falls and fractures and decreased quality of life.

Research question

Does foot-strike contact variability also increase during turning, as previously reported in straight gait in PD patients with Freezing of Gait (FOG)?

Methods

Subjects were instructed to walk on a gait mat, making "normal pivot" (180°) turns at each end. ProtoKinetics Movement Analysis Software (PKMAS) software was used for analysis. Video recordings and foot-pressure-prints were studied to identify and define turn segments. Spatiotemporal gait and turn measures were then determined only for the turn segments. A movement disorders neurologist determined clinical
