Effects of iVR Treadmill on Gait in PD

Parkinson's Disease (PD) patients suffer from gait impairments responsible for falls and bad quality of life: reduced speed and stride length, randomness in stride duration variability (reduced Long-Range Autocorrelations (LRA)). This pilot study will compare the spatio-temporal walking parameters and LRA of PD patients tested under three conditions: walking over ground, walking on a treadmill and walking on a treadmill in virtual reality. The aim is to determine the effect on gait of an optical flow recreated in virtual reality, by means of a virtual reality headset, on a treadmill.
