Use of "Smart Wheelchairs" to Provide Independent Mobility to Visual and Mobility Impairments

An interventional study of Smart Power Assistance Module (SPAM) and Smart Wheelchair Component System (SWCS) in Blindness and Spinal Cord Injury, sponsored by VA Office of Research and Development. Completed at 2 sites in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2015-12-03.

Study summary

The goal of this project is to evaluate the Smart Wheelchair Component System (SWCS) for power wheelchairs and the Smart Power Assistance Module (SPAM) for manual wheelchairs in realistic indoor environments with target users performing realistic tasks. We will combine group trials involving individuals who have a visual impairment (but do not have a mobility impairment) with several single-case studio involving individuals who have a visual and mobility impairment. Our long-term objective is to provide independent mobility to veterans with mobility and sensory impairments.

Read the detailed description

There are currently very few mobility options for veterans who have a mobility impairment and visual impairment, and this population will grow as the number of older veteran's increases. The goal of this project is to evaluate the Smart Wheelchair Component System (SWCS) for power wheelchairs and the Smart Power Assistance Module (SPAM) for manual wheelchairs in realistic indoor environments with target users performing realistic tasks. We will combine group trials involving individuals who have a visual impairment (and may or may not have a mobility impairment) with several single-case studies involving individuals who have a visual and mobility impairment.

The key questions that will be addresses by the proposed research are:

Can smart wheelchair technology improve performance on realistic navigation tasks for individuals with visual and mobility impairments?

Will smart wheelchair technology increase the amount of independent travel by individuals with visual and mobility impairments?

Will using a smart wheelchair for an extended period of time diminish a person's ability to operate a "traditional" wheeled mobility aid?

What researchers measure

Primary outcomes

  1. Time to Complete Trial Wheelchair Course

    Time to complete the course was recorded. The indoor course was set up in the research laboratory to include a straight path and 90 degree turns that included obstacles such as a cardboard box, a large orange cone, and a desk chair. The location of these obstacles were randomly placed in order to test whether or not the SPAM or SWCS was able to detect objects.

    Time frame: Two years

Results

Posted Dec 3, 2015
Limitations and caveats
Only four subjects actually tested the chair. It was decided to stop after these four subject tests because the chairs were clearly not viable for this population of persons who were totally blind, and thus there was no need for further testing.
