Evaluating the functionality and usability of two novel wheelchair anti-rollback devices for ramp ascent in manual wheelchair users with spinal cord injury

Difficulty ascending ramps and inclines with a manual wheelchair adversely impacts everyday mobility and overall quality of life of manual wheelchair users. Currently, various anti-rollback devices are available to assist manual wheelchair users to ascend ramps and inclines. However, these devices have two main shortcomings, (i) restriction to backward motion limiting recovery from an overturning wheelie which is a safety concern and, (ii) difficulty in engaging/disengaging the device while on ramp.
