Altered Dynamic Postural Control during Step Turning in Persons with Early-Stage Parkinson’s Disease

<table>Laboratory setup. Dashed line: starting point;  A: first trigger; B: second trigger; black square: force plate (AMTI 1.2 m × 1.2 m, 1560 Hz). Two stanchions were placed at the midpoint of each force plate. Starting point to A: 1 m. A to B: 2.4 m. B to force plate: 0.6 m. Force plate to stanchions: 0.6 m.</table>
