Evaluating the effectiveness of virtual reality-based therapy as an adjunct to conventional rehabilitation in the management of adolescents with cerebral palsy: An intervention protocol
Abstract
Virtual reality (VR)-based therapy has demonstrated potential in enhancing upper and lower limb functions, postural control, and balance. Despite its growing use, evidence regarding its impact on physical function and quality of life (QoL) in individuals with cerebral palsy (CP) remains scarce. This study protocol outlines a randomized controlled trial (RCT) designed to evaluate the efficacy of VR-based therapy as an adjunct to conventional therapy on physical function and QoL in adolescents with CP, as well as to explore the perceptions of participants and their caregivers regarding the intervention. This RCT will include 56 adolescents with CP, aged 10-17 years, who will be randomly assigned in a 1:1 ratio to either the intervention group (VR-based therapy) or the control group. Both groups will receive their usual conventional therapy, equated between groups. Additionally, the intervention group will receive VR therapy using the Xbox 360 Kinect, delivered twice weekly in 45- to 60-minute sessions for 12 weeks. Outcome measures will include the Gross Motor Function Measure-88, the 6-Minute Walk Test, handheld dynamometry, and the Paediatric Quality of Life Inventory. Assessments will be conducted at baseline, mid-intervention (week 6), and post-intervention (week 12). Qualitative data will be collected through semi-structured interviews with participants and caregivers after the 12-week program. Statistical analyses will be conducted on an intention-to-treat basis. Repeated measures ANOVA will be used to evaluate changes in physical function and QoL over time at baseline, mid- and post-intervention. The qualitative data from interviews will be analyzed using thematic analysis to identify key themes related to the experiences and perceptions of caregivers and participants.
