Title: Independently Operated Footrests: Design Concepts
Author: Holland, Kimberly ; Han, Randy ; Wells, Taylor ; Bell, Katherine
Abstract: Mid-drive power wheel chairs (PWC) have become more popular in recent years. However, due to the placement of the front casters, the traditional side-mounted footrests have been replaced by a single center-mounted footrest. Unfortunately, center-mounted footrests do not have a lift/lower mechanism that is easily operable by certain PWC users who transfer independently. Many PWC users have limited trunk strength, limited range of motion, decreased sensitivity in their lower body, and lack of fine motor function. This causes difficulty reaching the footrest to raise it. There is a need for a design solution that allows PWC users to independently lift and lower the footrest.
