Pablo is a new virtual reality (VR) game combined with wearable motion sensor system which can targeted intervention in an interactive environment, immediate and sensitive feedback about the user's performance, a motivating effect due to game-based feature. Unlike commercial camera systems such as Kinect or force platforms, the systems require a continuous sightline or restrict the base of support which may increase risk of falling. Few of studies had investigated the rehabilitation effects on balance with Pablo for patients with stroke.~PURPOSE: The purpose of this study is to investigate the effects of virtual reality training through Pablo system in patients with chronic stroke.~METHODS: A prospective, randomized, controlled, blinded assessor design was used. Patients with stroke were recruited and randomly assigned to a virtual reality(VR) group (n = 20) and functional balance training (FBT) group (n = 20). After 18 training sessions (60 minutes per session, 2 sessions per week), outcome measures which included the Berg Balance Scale, the Timed Up and Go Test (cognition), a gait analysis, the Activities-Specific Balance Confidence scale, Stroke Impact Scale (SIS), Level of pleasure, and frequency of adverse events. The data were analyzed using nonparametric tests, and significance was indicated at α < 0.05.
