Using Augmented Reality to Promote Physical Activity in Children With Cerebral Palsy

Muscle weakness in cerebral palsy (CP) results in a reduced level of physical activity. Reduced physical activity can lead to adverse health consequences. Augmented reality (AR) is increasingly being used to promote physical activity. The purpose of this study is to determine if adaptive exercise gaming program utilizing AR mobile app for children with cerebral palsy can promote physical activity through a prospective pilot study. Children with CP, GMFCS I-II between the ages of 5-18 years old will be recruited to participate in a home-based physical activity AR games. Study Population: Inclusion criteria are: diagnosis of cerebral palsy, ambulatory (GMFCS I and II), ages 5-18 years, English or Spanish speaking, and no plans for lower extremity surgery in the next 2 months. Exclusion criteria are: moderate to severe developmental or cognitive delay, severe visual or hearing condition, recent casting or surgical procedure over the past 4 months that impacts physical activity, or G-tube dependent. Interested participants will be scheduled for a virtual or in person visit in which informed consent will be obtained. Study Design: All participants will use the app for 4-weeks. The app will be implemented with an iPad® provided by the research team if the participant does not have a compatible device, that will be securely integrated with a network-server for real-time data access and storage. Participants will be provided an on-site or virtual CHLA tutorial about using the app and set up of the gaming system. Augment Therapy support personnel will assist with home set up if needed. Participants will access their home program on the app at least for 20 minutes, 3 times a week over a 4-week period. A coordinator will check in virtually with the participant during the course of the program. Exercise data will be collected and stored through the Augment Therapy™ app and self log book. Feasibility will be defined as 1) Program Engagement measured by the app and program evaluation surveys 2) Program Adherence measured by exercise compliance defined as the number of self-reported exercises logged, app usage logs, and sessions completed for the intervention and control groups. Validated questionnaires will be administered to evaluate the effect of the intervention at baseline and final assessment.
