The purpose of this research study is to examine whether computer based or virtual reality tests are as useful as real 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 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 assessments that present dynamic tasks and determine whether skills on these tasks correlate with functional motor abilities.

Arms Assigned Interventions
Experimental: Arm 1
All subjects
Other: Power Mobility Road Test (PMRT)
All subjects will undergo the "real world" power mobility evaluation via the PMRT.
Other: Computer-Based Test
All subjects will undergo the computer-based evaluation designed to simulate real world driving in a 2D environment.
Other: Virtual Reality Test
All subjects will undergo the virtual-based evaluation designed to simulate real world driving in a 3D environment.

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

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.
