The Strada walker, created by Jack Koby and Carly Keyes of the University of Oregon, was built because the designers realized most walkers are not user-friendly, and cause their owners to hunch their backs and strain their wrists while using them. 

The Strada, by contrast, utilizes upright design, adjustable forearm supports, special hand grips and low-impact tires, making for smoother use. It was a US national runner-up.
