Background: Power wheelchairs capable of overcoming environmental barriers, such
as uneven terrain, curbs, or stairs, have been under development for more than a
decade. Method: We conducted a systematic review of the scientific and
engineering literature to identify these devices, and we provide brief
descriptions of the mechanism and method of operation for each. We also present
data comparing their capabilities in terms of step climbing and standard
wheelchair functions. Results: We found that all the devices presented allow for
traversal of obstacles that cannot be accomplished with traditional power
wheelchairs, but the slow speeds and small wheel diameters of some designs make
them only moderately effective in the basic area of efficient transport over
level ground and the size and configuration of some others limit maneuverability
in tight spaces. Conclusion: We propose that safety and performance test methods
more comprehensive than the International Organization for Standards (ISO)
testing protocols be developed for measuring the capabilities of advanced
wheelchairs with step-climbing and other environment-negotiating features to
allow comparison of their clinical effectiveness.
