Home Exercise Program Using Bootle Boot Camp

This study aims to learn about the engagement and lower limb motor outcomes of children with cerebral palsy, ages 6-12 years, GMFCS Levels I-II, engaging in home-based movement practice using a novel therapy exercise Application, Bootle Boot Camp, offered with and without movement-tracking feedback.

Adherence to home exercise programs is low. Interactive computer play (ICP) - any kind of computer game or virtual reality technology that allows users to interact with simulated objects in a virtual environment - offers a fun and motivational way to increase movement practice.

Bootle Boot Camp is a novel ICP technology developed by the Possibility Engineering and Research Lab at Holland Bloorview Kids Rehabilitation Hospital that uses a 3D motion tracking camera to provide real time feedback on skeletal movements during game play. It allows physiotherapists to prescribe personalized lower limb home exercise programs to clients.

The investigator's specific objectives are:

1. To compare participants' level of affective, behavioural, and cognitive engagement with Bootle Boot Camp with and without movement tracking feedback
2. To determine the quality of exercise performance when participants use Bootle Boot Camp with and without movement tracking feedback
3. To estimate the treatment response associated with use of Bootle Boot Camp
4. To explore physiotherapists, children, and their caregivers' experiences with the App.

Children with cerebral palsy (ages 6-12 years, GMFCS Level I or II) will be prescribed a home exercise program by their treating physiotherapist that they will complete independently using the App on their television at home. Bootle Boot Camp exercise sessions offered with movement-tracking feedback will be alternated with sessions offered without feedback for 4 weeks (4 sessions per week). Following this comparison period, the version of the App providing the most therapeutic data pattern based on system data and children's input will be used for an additional 2 weeks. Post 6 weeks of Bootle Boot Camp game play, children and caregivers will be asked to take part in semi-structured interviews to learn more about families' experiences with the home program
