IndieTrainer: Enabling Individuals With Cerebral Palsy to Receive Gamified Power Mobility Training in Their Own Manual Wheelchairs

Study Overview
=================
Brief Summary
-----------------
Power wheelchairs (PWCs) offer children who are unable to independently opportunities for participation in social, educational, and leisure activities. Unfortunately, children who have severe cognitive, motor, or sensory impairments may need extended training to be able to master the PWC skills needed to qualify for their own PWC. The IndieTrainer system was developed to address this need. The IndieTrainer system is comprised of the IndieGo device and video-game modules. The IndieGo device temporarily converts a manual wheelchair into a powered wheelchair, thereby allowing children to remain in their own manual wheelchair and use their own custom seating system during power wheelchair skills training activities. The video-game modules are integrated into the IndieGo device such that the video games can be played on a TV screen using the specific access method used to control the IndieGo (i.e., switch or joystick). The IndieTrainer system is designed to allow a child to practice power wheelchair skills as part of the video-game modules or as part of more traditional power wheelchair skills training activities wherein children are able to actively explore the environment and practice executing actual wheelchair skills. This study will evaluate the use of the IndieTrainer system in children with cerebral palsy, ages 5-21 years.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in understanding how to use a power mobility device | This outcome will be assessed using each participant's score (from a low of Phase 1 to a high of Phase 8) on the Assessment of Learning Powered mobility use. The Assessment of Learning Powered mobility use (ALP) is a process-based measure detailing 8 phases of learning (Phase 1 - Novice to Phase 8 - Expert) within 3 stages: Stage 1 - the Introvert Stage where the child focuses on exploring cause and effect within the function of the power mobility device; Stage 2 - the Explore Sequencing Stage where the child focuses on how to sequence the operations to maneuver the power mobility device; and Stage 3 - the Extrovert Stage where the child is focused on using the power mobility device in daily life. Higher scores therefore indicate a better outcome. | Baseline- pre-intervention, immediately after the conclusion of the intervention period, and at the single session retention trial 4 weeks after the end of the intervention period | 
| Change in power mobility skill performance | This outcome will be assessed using the Wheelchair Skills Checklist, a task-based measure that evaluates a child's performance of 7 specific power mobility skills using a 3-point ordinal scale from 0-2 where a score of 0 indicates the participant Does Not Perform the skill, a score of 1 indicates that the skill is Emerging, and a score of 2 indicates the participant Performs the Skill. Higher scores therefore indicate a better outcome. | Baseline-pre-intervention, immediately after the conclusion of the intervention period, and at the single session retention trial 4 weeks after the end of the intervention period | 
| Change in power mobility skills performance | This outcome will be assessed using the Canadian Occupational Performance Measure to identify, prioritize, and rate parent/caregiver perceptions of children's performance of power mobility skills. A total of 4-5 occupational performance issues in the area of power mobility skills will be identified and scored on a 1-10 scale, where a 1 is the lowest score and a 10 is the highest score, for both the caregiver's perception of the child's performance and their satisfaction with the child's performance. | Baseline-pre-intervention and immediately after the conclusion of the intervention period, | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in perceptions regarding the IndieTrainer system intervention | Parental/caregivers' perceptions of the IndieTrainer system intervention will be gathered via a recorded qualitative interview. An interview guide has been developed for this purpose. | Baseline -pre-intervention and immediately after the conclusion of the intervention | 
| Parent/caregiver satisfaction with the IndieTrainer system | This outcome will be assessed at post-intervention through use of the Client Satisfaction Questionnaire-8 | Immediately after the conclusion of the intervention |
