Nonimmersive Virtual Reality as Complementary Rehabilitation on Functional Mobility and Gait in Cerebral Palsy: A Randomized Controlled Clinical Trial

Objective: This study aimed to investigate the effects of nonimmersive virtual reality (VR) as complementary rehabilitation on functional mobility and gait in children with mild unilateral cerebral palsy (CP). Methods: Prospective, randomized, controlled, clinical trial. Twenty-two children with unilateral CP were randomized into two groups: intervention group (IG) (n = 11) and control group (n = 11). After baseline assessments, the participants either started the VR intervention (IG) associated with conventional therapy, or continued conventional physical therapy (control group). Participants in the IG attended 45-minute training sessions twice a week for 8 weeks (total: 16 sessions and 12 hours of training). Participants in the control group underwent standard therapy for 50 minutes, twice a week. Timed Up and Go test (TUG), gait spatiotemporal variables, and pelvic angles were measured at baseline and after treatment sessions. Results: When compared with the control group, the IG performed the following activities in decreased time: TUG, and stride time. Also, the IG increased the velocity of walking and the pelvis retroversion, and decreased the pelvis interval/external rotations and amplitude of pelvis rotation while walking. Conclusions: A rehabilitative approach based on a nonimmersive VR as complementary rehabilitation may improve functional mobility and change joint mobility functions during gait of children with mild unilateral CP. The results of the study demonstrate that the insertion of a therapy based on VR may help in better strategies in the gait of children with CP. Thus, rehabilitation professionals can use this tool combined with conventional therapy. (AU)
