Two weeks of twice-daily prism adaptation treatment does not improve posture or gait in Parkinson's disease: a double-blind randomized controlled trial.

ABSTRACT:

Background

Gait difficulties in Parkinson's disease have been related to problems shifting the center of gravity forward. We previously showed reduced forward stepping latencies for people with Parkinson's disease after one session of adaptation to upward visual shifts, which produces downward motor after-effects and potentially shifts the center of gravity forward. Here we tested if repeated prism adaptation improved gait and postural control in Parkinson's disease through a parallel, double-blind, randomized, sham-controlled trial.

Methods

We recruited participants with idiopathic Parkinson's disease aged 40-85 and meeting any one of three clinical criteria: (1) Hoehn and Yahr Stage II.5-IV; (2) scoring > 0 on the gait, freezing of gait, and/or postural stability items of
