|Power Wheelchair Mild Cognitive Impairment Spinal Cord Injuries||Behavioral: CoPILOT||Phase 1|
Background: Powered wheelchairs can improve participation in daily life, increase quality of life, and add 'life to years' for individuals with SCI. Cognitive limitations, associated with advanced age at the time of a spinal cord injury or comorbid traumatic brain injury, impair learning and may prevent an individual from acquiring or maintaining skills necessary to drive a powered mobility device. Standard power wheelchair training, limited by time, equipment and budget constraints, may not meet the learning needs of individuals with cognitive impairment, preventing an individual from obtaining use of a powered wheelchair, impacting independence and quality of life. The total system cost of procuring a power wheelchair can range from $10,000 - $30,000; suboptimal use resulting from inadequate training is a poor use of resources and comes at a substantial social price. The Collaborative Power mobility Innovative Learning OpporTunity (CoPILOT) is a training approach utilizing shared control wheelchair technology and allows a therapist to provide an error-free learning experience for individuals in their own environments, while maintaining safety of the user and the individuals around them. Using shared control technology, the wheelchair user remains in control of the wheelchair while learning to drive, except in cases where the trainer overrides the control (using a remote controlled interface) to maintain safety and provide targeted learning opportunities.
Purpose and Objectives: Our purpose is to obtain pilot data for a larger randomized control trial of a shared control power wheelchair training program (CoPILOT) for improving power wheelchair mobility skills among novice power wheelchair users with comorbid cognitive impairment compared to standard of care. Collection of pilot data is necessary prior to moving forward with a larger randomized controlled trial (RCT).
Hypotheses: We expect the intervention protocol will be feasible for a larger randomized control trial. Compared to the standard of care group, we expect the CoPILOT group will experience significant improvement in power wheelchair skill capacity. We also expect the CoPILOT group will experience improvements in wheelchair skill safety, confidence, capacity for divided attention tasks, and health related quality of life, compared to the standard of care participants.
Methods: Our feasibility study will use an evaluator blind parallel RCT. New power wheelchair users with mild to moderate cognitive impairment will be recruited from the GF Strong or Vancouver General Hospital Spinal Cord Injury patient population. Participants will be randomly assigned to a CoPILOT (shared control training) group or standard of care group. All training will be completed by qualified occupational therapist trainers. Participants in both groups will receive 12 hours of training in a standard powered wheelchair; however, the CoPILOT groups will use remote control technology we have developed. Post-Treatment Qualitative Interviews will be conducted. Questions will be related to protocol administration and use of the CoPILOT approach and shared control technology, including necessary modifications.

|Official Title:||Collaborative Power Mobility Innovative Learning OpporTunity (CoPILOT) - A Pilot Study of a New Training Approach (Phase 1)|
|Study Start Date :||October 2016|
|Estimated Primary Completion Date :||May 2019|
Experimental group participants will receive structured training in a standard powered wheelchair using the CoPILOT shared control wheelchair technology consisting of 12 hours total training time (one hour, four times per week for three weeks).
Participants in both groups will receive twelve hours of training in a standard powered wheelchair however the CoPILOT groups will use remote control technology we have developed. The technology provides the trainer with remote control of wheelchair speed and direction allowing the trainer to override the participant's actions as needed to ensure safe error-free shared controlled wheelchair training. The CoPILOT approach will accommodate varied learning needs, as per adult learning principles, while decreasing trainer input until the participant can complete tasks independently.
No Intervention: Standard of Care
Standard of care participants will receive training according to the standard of care in rehabilitation facilities in the Vancouver area in a standard powered wheelchair, consisting of 12 hour protocols in a standard power wheelchair (one hour, four times per week for three weeks).
- Change in Power-mobility Indoor Driving Assessment (PIDA) [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]The PIDA covers specific tasks required for functional indoor driving, which are specific to the environment (i.e. accessing the bed from the right and left, and approaching the closet and dresser in the bedroom). The PIDA has been evaluated for content and face validity, has good inter-rater (ICC 0.87) and fair intra-rater (ICC 0.67) reliability.55. We aim to explore the potential usefulness of this outcome measure for this population, in this environment, for inclusion in future clinical trials.
- Change in Wheelchair Skills Test Questionnaire (WST-P-Q) [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]The WST-P-Q is a standardized subjective evaluation of the capacity, performance, and confidence for 30 powered wheelchair skills. Total percent scores (0-100%) are calculated for both capacity, performance, and confidence. The WST was selected as a secondary measure because it is a standardized tool for evaluating wheelchair capacity, the primary construct of interest.
- Change in Wheelchair-use Confidence Scale (WheelCon-P ) [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]This measurement for power wheelchair users is a 59-item self-report scale (0-100) with documented reliability and validity. Responses indicate current level of perceived confidence (%) to navigate the physical environment in a wheelchair, perform activities in a wheelchair, problem solve, advocate for specific needs, and manage social situations and emotions. The WheelCon was selected as a secondary outcome measure because confidence for using a wheelchair has been shown to influence wheelchair skills capacity.
- Change in Health Utility Index Mark 3 (HUI3) [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]Health utility measurement is useful in performing cost-utility and cost-effectiveness analyses of new rehabilitation interventions. The HUI3 is a brief questionnaire that asks subjects about their health status, reflected in a single-score measure of health-related quality of life (HRQOL).
- Change in The Wheelchair Outcome Measure (WhOM) [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]The WhOM assess the individual's wheelchair related goals, the importance of those goals, and the satisfaction in their ability to complete those tasks. This will be used to assess goal attainment (performance and satisfaction) following training.
- The Wheeling While Talking Test [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]The Wheeling While Talking Test assesses the individual's ability to complete wheeling tasks under divided attention conditions. This test is being evaluated for use in powered wheelchair studies.
- Sensory data [ Time Frame: Baseline (pre-randomization), 5 weeks (immediate post-intervention) ]A variety of anonymized sensor data will be collected (not linked to participant files). Data will be used to characterize situations which were deemed unsafe by the trainer, and to analyse steering and intervention behaviours. The following sensor data will be collected from the wheelchair control system (computerized): Joystick movements and button presses (both trainer and participant) and wheelchair movements (odometry). The following sensors data will be collected from sensors attached to the wheelchair: distance to obstacles (laser rangefinders), environmental context (outward looking RGBD cameras), wheelchair movements (accelerometer, gyroscope, compass).
