Abstract

Virtual reality based therapy (VRBT) refers to the use of interactive simulations to present users with opportunities to perform neurorehabilitation in virtual environments that appear, sound, and less frequently, feel similar to real-world objects and events. This study compared the effects of 2 off-the-shelf gaming system devices on standing balance and weight shifting for persons with Cerebral Palsy (PWCP) following single event multilevel lever arm restoration and anti spasticity surgery (SEMLARASS). A prospective experimental study was conducted among 80 PWCP post SEMLARASS aged 5–20 years and randomly assigned into Group A (n = 40): received the VRBT with Xbox 360 with Kinect (XwK) and Group B (n = 40): received the VRBT with Nintendo Wii with Balance Board (WwB). The study duration was 5 weeks with 30 minutes of intervention per day for 6 days per week in each group. A total of 3 games (5 choices) were played per session supervised by a physiotherapist. Paediatric Balance Scale (PBS) and Dynamic Gait Index (DGI) were the primary outcome measures, performed at baseline, 5 weeks after the treatment and follow-ups after 1 month and 3 months. The additional outcomes measured were walking test, steadiness test, COG and single-leg standing test using the stabilometer of the Wii balance board. Both the groups improved significantly after the intervention. However, Group A showed significant difference in PBS (P < 0.01) and DGI (P < 0.05) when compared to group B. The obtained outcomes were maintained at 1 month and 3 months follow-up. The X box 360 had a better connect to the virtual in comparison to the Nintendo Wii as reported by the users. While both devices were found effective, VRBT with XwKwas superior toWwB for improving standing balance and weight shifting in CWCP after SEMLARASS.
