  Purpose

The purpose of this research study is to examine whether computer based or virtual reality based driving assessments are as useful as real-world power wheelchair driving tests in measuring driving performance and whether they may be useful in helping to identify the problems that some individuals may have with driving power wheelchairs. The specific aims are as follows:

Specific Aim 1: To develop computer-based and VR-based wheelchair driving assessments for both drivers and non-drivers that correspond to an accepted real-world driving assessment (Power Mobility Road Test) and compare them to the real-world assessment and to each other.

Specific Aim 2: To develop additional features of the computer-based and VR-based assessments that present dynamic tasks and determine whether skills on these tasks can be delineated within the virtual environment.

Primary Outcome Measures:
  • Composite Power Mobility Road Test (PMRT) Scores [ Time Frame: Baseline in-lab testing ] [ Designated as safety issue: No ]
    The computer-based and the virtual environments will be modeled after and scored similarly to the real world PMRT. The PMRT contains two domains: Structured Elements/Tasks and Unstructured Skilled Driving. The first domains contain 16 tasks that include activities such as passing through standard width doorways, and turning a ninety-degree turn, turning 180 degrees. In both domains, each task is scored from 1 to 4, depending on speed and the number of collisions that occur with obstacles. A total score for the entire test is calculated out of a possible 64 points, and the final score on the test reflects the percentage of total points acquired1. A passing score is a percentage of > 95%.

Groups/Cohorts Assigned Interventions
Condition 1 (PC Screens with No Rollers)
All subjects (Repeated - measures study design): All subjects were evaluated with the Power Mobility Road Test (PMRT).

All subjects will underwent the Power Mobility Road Test (PMRT), and the clinicians scored the driving performance within each condition.
Condition 2 (PC Screens with Rollers)
All subjects (Repeated - measures study design): All subjects were evaluated with the Power Mobility Road Test (PMRT).
Other: Power Mobility Road Test (PMRT)
All subjects will underwent the Power Mobility Road Test (PMRT), and the clinicians scored the driving performance within each condition.
Condition 3 (VR Screens with No Rollers)
All subjects (Repeated - measures study design): All subjects were evaluated with the Power Mobility Road Test (PMRT).
Other: Power Mobility Road Test (PMRT)
All subjects will underwent the Power Mobility Road Test (PMRT), and the clinicians scored the driving performance within each condition.
Condition 4 (VR Screens with Rollers)
All subjects (Repeated - measures study design): All subjects were evaluated with the Power Mobility Road Test (PMRT).
Other: Power Mobility Road Test (PMRT)
All subjects will underwent the Power Mobility Road Test (PMRT), and the clinicians scored the driving performance within each condition.
Condntion 5 (Real-world driving)
All subjects (Repeated - measures study design): All subjects were evaluated with the Power Mobility Road Test (PMRT).
Other: Power Mobility Road Test (PMRT)
All subjects will underwent the Power Mobility Road Test (PMRT), and the clinicians scored the driving performance within each condition.

  Eligibility

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

People with physical disabilities who have a mobility impairment due to any any spinal cord disease condition (e.g. Spinal Cord Injury, Spina Bifida)

Criteria

Inclusion Criteria:

  • Subjects must be between 18 to 80 years old.
  • Subjects must have a diagnosis of SCI, spina bifida, syringomyelia, spinal stenosis, transverse myelitis, ALS, spinal cord disease, multiple sclerosis, stroke, polytraumatic injury, or TBI with residual motor, sensory, or cognitive impairments that impair mobility.
  • Subjects must use a power wheelchair or an attendant propelled manual wheelchair for all or part of their mobility.
  • Subjects must be able to provide informed consent.
  • Subjects must have very basic cognitive, visual, and motor skills to interact with an interface.

Exclusion Criteria:

  • Subjects who have active pelvic or thigh wounds. (They may be worsened by prolonged sitting).
  • Subjects with a history of seizures in the last 90 days. (A computer screen task has the potential to induce seizures).
  • Subjects who do not pass the screening protocol.
