Paper presents a mobile and portable device which can simulate the same gait altering movements experienced by post-stroke patients on a split belt treadmill, a system that has two belts than can be run at different speeds. The Gait Enhancing Mobile Shoe (GEMS) imitates the relative foot motion experienced on a split belt treadmill, but while walking over ground. The GEMS utilizes the wearer’s downward force by converting it into a horizontal backward motion. The force is redirected by using a specially sized Archimedean spiral wheel shape that actually pushes the wearer’s foot backward. An onboard magnetic particle brake applies a resistance torque through an internal gear train which in turn controls the velocity of the shoe’s backward motion. The shoe is powered by a small battery pack worn around the waist. The shoe is easily adjustable to different horizontal push length, force, speed, and direction by adjusting the wheel size, wheel shape, and magnetic particle brake resistance. Planned research including user testing of the GEMS in various environments is discussed.
