Several studies have shown that patients motivation plays a crucial role in determining therapy outcome. However few studies have demonstrated the potential of VR in pediatric rehabilitation. Therefore we developed a VR-based soccer scenario which provided interactive elements to engage patients during robotic assisted treadmill training RAGT . The aim of this study was to compare the immediate effect of different supportive conditions VR versus non-VR conditions on motor output in patients and healthy control children during training with the driven gait orthosis Lokomat . Methods A total of 18 children ten patients with different neurological gait disorders eight healthy controls took part in this study. They were instructed to walk on the Lokomat in four different randomly-presented conditions 1 walk normally without supporting assistance 2 with therapists instructions to promote active participation 3 with VR as a motivating tool to walk actively and 4 with the VR tool combined with therapists instructions. The Lokomat gait orthosis is equipped with sensors at hip and knee joint to measure man-machine interaction forces. Additionally subjects acceptance of the RAGT with VR was assessed using a questionnaire. Results The mixed ANOVA revealed significant main effects for the factor CONDITIONS p and a significant interaction CONDITIONS X GROUP p . Tests of .
