Quantifying Electric-Powered Wheelchair (EPW) Driving Performance Using Jerk Metrics: A Pilot Study
Background Current assessments of electric-powered wheelchair (EPW) driving, such as the Wheelchair Skills Test (WST), rely on observational scoring and lack validation in outdoor environments. Occupational Therapists require standardized, quantitative measures to evaluate driving performance and monitor training progress. Objective This pilot study examined: (1) the influence of cognitive, physical, and sensory components on EPW driving, (2) the validity of sensor-derived jerk metrics relative to WST scores, and ( …
