Objective To assess the stability of clinicians' and users' rating of electric-powered wheelchair (EPW) driving while using 4 different human-machine interfaces (HMIs) within the Virtual Reality–based SIMulator–version 2 (VRSIM-2) and in the real world (accounting for a total of 5 unique driving conditions). Design Within-subjects repeated-measures design. Setting Simulation-based assessment in a research laboratory. Participants A convenience sample of EPW athletes (N=21) recruited at the 31st National Veterans Wheelchair Games. Interventions Not applicable. Main Outcome Measures Composite PMRT scores from the Power Mobility Road Test (PMRT); Raw Task Load Index; and the 6 subscale scores from the Task Load Index developed by the National Aeronautics and Space Administration (NASA-TLX). Results There was moderate stability (intraclass correlation coefficient between .50 and .75) in the total composite PMRT scores (P<.001 and the users self-reported performance scores among driving conditions. there was a significant difference in workload different conditions as reflected by raw task load index subanalyses revealed this due to mental demand frustration subscales. post hoc analyses that these differences nasa-tlx subscale were between real-world virtual particularly attributable lacked rollers part of simulation.> Conclusions Further design improvements in the simulator to increase immersion experienced by the EPW user, along with a standardized training program for clinicians to deliver PMRT in VRSIM-2, could improve the stability between the different HMIs and real-world driving. |
