Book Description
"Powered wheelchair (PW) driving is a complex activity and requires the acquisition of several skills. Given the risks involved with PW use, safe and effective training methods are needed. Virtual reality training allows users to practice difficult tasks in a safe environment. An additional benefit is that augmented feedback can be provided to optimize learning. The purpose of this thesis was to design an optimal training strategy for PW training using concepts from motor learning. The objectives of this thesis were: 1) to review the literature to identify PW tasks and performance outcomes; 2) to investigate whether providing augmented feedback during powered wheelchair simulator training results in superior performance, and whether skills learned in a virtual environment transfer to real PW driving. In part one of this thesis, a scoping review of the literature was conducted to extract PW tasks and performance outcomes used when training and/or assessing PW skills. The results of the review were used to inform the design of the virtual PW task. The second manuscript contains the results of an experiment that investigated the effect of augmented feedback during simulator training on PW driving performance. Forty healthy young adults were recruited and randomly allocated to two groups: one group received feedback during simulator training while the control group received no feedback. PW driving performance was assessed at baseline in both the real and virtual environment. After training in the virtual environment, a post-test in the VE was administered to assess initial skill acquisition. Two days later, participants returned for a retention test in the VE and a transfer test in the RE. A significant difference in the speed-accuracy distributions before and after training in the VE were found for the group receiving augmented feedback, whereas the difference was not significant for the control group. Participants had significantly better performance with the real PW two days after training in comparison to baseline. Simulator training results in better performance and in transfer of skills to real PW driving. Effects of augmented feedback were only seen when looking at differences in the speed-accuracy distributions, highlighting the importance of accounting for the speed-accuracy tradeoff for PW driving." --

Book Description
"For new manual wheelchair (MWC) users, mastering safe and efficient propulsion technique is critical, as poor technique elevates risk for chronic upper limb pain and injury. Virtual reality (VR) simulators allow users to practice such tasks in a safe, controlled, and realistic environment. Additionally, augmented feedback (AF) may be provided in order to optimize motor learning. The objective of this thesis was to investigate the effects of providing AF with various delivery schedules on motor learning of this complex skill, as well as to determine whether a propulsion technique learned in a virtual environment transfers effectively to real-world, over-ground propulsion. The included manuscript describes a motor learning study in which 30 healthy participants aged 18-35 were randomly assigned to three groups. During a VR propulsion training session, the high-frequency feedback group received AF throughout all propulsion training; the faded feedback group received AF in a faded schedule; and the control group underwent training with no AF. Propulsion assessments were performed at baseline (in virtual – VE and real environments – RE), 5 minutes after training (in VE), and 48 hours after training (in VE and RE to assess retention and transfer of skill, respectively). Compared to the control group, significant improvements were found for both feedback groups. Additionally, this learning transferred effectively to real-world propulsion. Small, non-significant differences were also found between the high-frequency and faded feedback groups. VR propulsion training is effective for development, retention, and transfer of appropriate technique only when such training includes AF about propulsion biomechanics. By highlighting the importance of AF during propulsion training, findings from this thesis provide valuable insight for the design of low-cost training programs to help prevent the detrimental upper limb pain and injury that currently affects as many as 73% of MWC users"--
