User-friendliness of a Portable Driving Simulator

August 15, 2024 updated by: University of Kansas Medical Center

User-friendliness of a Portable Driving Simulator to Retrain Impaired Driving Skills in Stroke Survivors and in Individuals With Parkinson's Disease and Multiple Sclerosis

The use of simulators to retrain driving skills of patients with stroke, Parkinson's disease (PD), or multiple sclerosis (MS) is very limited because of cost, space required, and incidence of simulator sickness in high fidelity simulators. The Principal investigator recently developed a low cost low fidelity portable driving simulator (PDS). In this pilot study, the study team will (1) determine the ease of use and occurrence of simulator sickness while operating the low fidelity PDS in a clinic setting and (2) the efficacy of the low fidelity PDS to reproduce the benefits from retraining impaired driving skills of stroke survivors in a high-fidelity simulator.

Participants: 30 participants, separated according to neurological condition including stroke, PD, or MS, will be randomly allocated to either the PDS or fixed-base high-fidelity simulator training. Each participant will undergo a pre-training evaluation, five hours of designated training and a post-training assessment, similar to the pre-training evaluation. Data will be analyzed according to study aims.

The investigators hypothesize that the simple set up of the PDS will make it easier to use and better decrease the incidence of simulator sickness that typically leads to stopping therapy than the high-fidelity simulator.

The investigators hypothesize that improvements in lane maintenance, adherence to speed limits, reaction to traffic lights, and overall reaction time after training using the PDS will not be significantly different from improvements observed after training using the high-fidelity driving simulator.

Study Overview

Detailed Description

Aims: The aims of the proposed study are to determine (1) the ease of use and development of simulator sickness while operating the low fidelity Portable Driving Simulator (PDS) in a clinic setting and (2) the efficacy of the low fidelity PDS to reproduce the benefits from retraining impaired driving skills of stroke survivors, persons with Parkinson's Disease (PD) or multiple sclerosis (MS) in a high-fidelity fixed-base simulator.

Hypotheses: For the first study aim 1, the investigators hypothesize that the simple set up of the PDS will make it easier to use and better mitigate incidence of simulator sickness that typically leads to attrition than in a high-fidelity simulator.

For study aim 2, the investigators hypothesize that improvements in lane maintenance, adherence to speed limits, reaction to traffic lights, and overall reaction time after training using the PDS will not be significantly different from improvements observed after training using the high-fidelity driving simulator.

Background: Currently, simulator-based training is the method with the best evidence of retraining impaired driving-related skills after stroke and with promise in individuals with Parkinson's disease (PD) or multiple sclerosis (MS). Driving simulators enable patients to retrain impaired driving skills in a context that evokes and ''mimics'' the perceptual, cognitive, and motor processes used in real-world driving. The fact that real-world traffic and driving situations can be presented many times over, without any safety risk, under full experimenter or clinician control, and with ''instant replay'' possibility to augment feedback enhances the utility of the driving simulator as an ideal tool for driving rehabilitation.

However, the use of simulators to retrain driving skills of patients with stroke, PD, or MS has been very limited because of three major reasons. The cost of currently available driving simulators (between $50,000 to $500,000), the space needed to house the simulators (15 to 50 square feet), and the incidence of simulator sickness (rate = 5 - 25%) in high-fidelity simulators. The principal investigator recently developed a low cost ($10,000) low fidelity portable driving simulator (PDS) in the University of Kansas Laboratory for Advanced Rehabilitation Research in Simulation (LARRS) that measures 25.5" Wide, 32.5" High, and 25" Deep and requires only approximately 4 square feet of space.

Study Objectives:

  1. Determine the ease of use and occurrence of simulator sickness while operating the low fidelity PDS in a clinic setting.
  2. Determine the efficacy of the low fidelity PDS to reproduce the benefits from retraining impaired driving skills of stroke survivors in a high-fidelity simulator.

Study Procedures: The study team will recruit 10 participants with a first ever stroke, 10 participants with PD (Hoehn & Yahr stage 2 or 3 during on-medication) and 10 participants with MS (Expanded Disability Status Scale between 3 and 6.5). Participants in each diagnosis group will be randomly allocated, based on a computer generated random sequence, into either the PDS or high-fidelity simulator training. The randomization process will be done by principal investigator. All participants will undergo a pre-training evaluation that includes driving-related physical, visual, and cognitive tests. Studies have shown that a minimum of five hours of training in a simulator is needed for meaningful improvement in driving skills. As such, each participant will receive five hours of the assigned training. The first session in the simulator will establish participants' baseline driving performance. The next three training sessions will be directed at addressing the deficits in specific skills identified from the baseline performance. The fifth session in the simulator will establish participants' post-training driving performance. All participants will again undergo a post-training evaluation similar to the pre-training evaluation. The five training sessions in the simulator will each last approximately one hour per day, twice or thrice a week, and will be completed in two weeks. The study coordinator, who will be blind to participants' group allocation, will administer both the pre- and post-training evaluations. A research student in the Laboratory for Advanced Rehabilitation Research in Simulation supervised by Dr. Hannes Devos and Dr. Abiodun Akinwuntan will train all participants.
