Bottom Line: When the user stands on the footpads, the system can move his or her feet while the body remains stationary.Therefore, we developed a graded-walking program for the system used in this study.An evaluation of the results of tests showed that the vastus medialis muscles of all the subjects were stimulated more than by walking on real slopes.

ABSTRACT
This paper describes the development of a gait rehabilitation system with a locomotion interface (LI) for home-visit rehabilitation. For this purpose, the LI should be compact, small, and easy to move. The LI has two 2 degree-of-freedom (DOF) manipulators with footpads to move each foot along a trajectory. When the user stands on the footpads, the system can move his or her feet while the body remains stationary. The footpads can have various trajectories, which are prerecordings of the movements of healthy individuals walking on plane surfaces or slopes. The homes of stroke patients may have not only flat surfaces but also some slopes and staircases. The quadriceps femoris muscle is important for walking up and down slopes and staircases, and the eccentric and concentric contractions of this muscle are, in particular, difficult to train under normal circumstances. Therefore, we developed a graded-walking program for the system used in this study. Using this system, the user can undergo gait rehabilitation in their home, during visits by a physical therapist. An evaluation of the results of tests showed that the vastus medialis muscles of all the subjects were stimulated more than by walking on real slopes.

Mentions: A combination of rotational transformation and vertical translation matrices (Equation (1)), was used to rotate the trajectory data, where x′′ and y′′ refer to the coordinates of the tilted trajectory, x and y are the coordinates of points for walking on a flat surface, α is the tilt angle, and y′ is the minimum value of y after tilting. The minimum point of the tilted trajectory was often underneath the floor. In order to set the height of the lowest point to zero (y = 0), the tilted y was subtracted from the y′ value after tilting (Figures 6 and 7). Consider(1)x′′y′′=cos⁡⁡α−sin⁡αsin⁡αcos⁡⁡αxy−0y′.
