Spatial constraints evoke increased number of steps during turning in Parkinsońs disease

A hallmark of parkinsonian gait phenomenology is the patients' difficulty to perform standing or walking turns. Turns require the patients to repeatedly shift their weight, and this frequently contributes to falls (Robinovitch et al., 2013). A recent project evaluated objective home-recorded data which demonstrated that people with Parkinson's disease (PwP) showed reduced performance in turning while the overall activity was similar compared to healthy controls (Mancini et al., 2015).
