(Purpose) This study investigated the effectiveness of a virtual reality (VR) -based exercise intervention program for children with cerebral palsy (CP) by analyzing the effect size of Cohen's d. (Methods) The PICO (Patient, Intervention, Comparison, Outcome) frameworks were used to structure the research questions for this study. Effect sizes (Cohen’s d) were calculated for the gait speed, cadence, stride length, and gross motor function measure-E (GMFM-E). Data Selection: Eight studies (2008–2023) were analyzed using the following keywords: cerebral palsy, physical activity, exercise, virtual reality, and gait. The databases included the National Assembly Library, the Academic Research Information Service, Google Scholar, and the US Medical Library Data Search(PubMed). (Results) Interventions lasted 2– 8 weeks, with 2–5 sessions/week (20–40 min/session), using devices like Nintendo Wii Fit, Xbox360, PC, and HMD. Effect sizes for gait parameters were gait speed (d=0.37–0.81, 4 studies), cadence (d=0.36–0.78, 3 studies), and stride length (d=0.33–0.91, 3 studies). GMFM-E scores showed small effect sizes (d=0.15–0.28, 4 studies). (Conclusions) VR -based interventions focusing on balance and postural control significantly enhanced gait parameters in children with CP.
