Project information
An immersive virtual reality-based exercise system was developed to support poststroke upper limb exercises. In a 2-week randomized controlled trial, fifty patients used the system for exercises (intervention) or a sham entertainment program (control). The findings demonstrate that the system can improve shoulder joint motion and is safe and acceptable.
