Combining Aerobic Exercise and Virtual Reality for Cognitive-motor Rehabilitation in PD

Participants will perform a 30-minute exercise protocol (5 minutes warm-up and cool-down each and 20 minutes moderate intensity exercise) on a StepOne™ recumbent stepper

Participants will interact with the virtual environment and view the gaming environment on a flat-screen TV placed in front of them at a suitable distance. The participants will play four games (50 repetitions/game divided into three blocks with 1-2 minutes rest between blocks), with the order of the games randomized in every session.
