J-Walk Gait Trainer (ME 470 Senior Design Capstone Project – Fall 2019)

Design of an Improved Gait Trainer Customized for Individual Needs


The J-Walk is a gait trainer mobility aid originally designed for an individual with cerebral palsy and crouch gait. The design features a commercially available rollator, the Triumph Escape, that has been modified to use posteriorly. This makes the design cheaper than some custom products. These plans will allow those with similar needs to customize their own mobility aid. This customization is based upon an individual with a specific need. Any individual can adjust the design according to their height and weight.
