Rehabilitation System

A split belt treadmill for gait rehabilitation was developed to improve the symmetry of the stance phase time of patients with stroke. The system, which increases the stance phase time of the affected leg and then realizes a well-balanced gait, is divided into two components. First, the stance phases of the sound and affected legs were measured and presented visually in real time to the patient and physical therapist as biofeedback. Second, using stance phase biofeedback, the physical therapist sets two different velocities of treadmill belts for sound and affected legs. In an experiment, 11 patients with chronic stroke participated in a short-term intervention trial (20 gait cycles) of the developed treadmill system. Three of the five subjects who had lost balance between the stance phase of the sound leg and that of the affected one improved their gait balance in the intervention trial. In addition, one subject kept the well-balanced gait after the intervention.

Objective: We developed a footpad-type locomotion interface called the GaitMaster. The purpose of this pilot study was to examine the effects of gait rehabilitation using the GaitMaster in chronic stroke patients. Design: Randomized cross-over design. Setting: An outpatient department. Subjects: Twelve patients with chronic post-stroke hemiparesis. Intervention: In group A, patients underwent an ‘intervention phase’ followed by a ‘non-intervention phase’, whereas in group B, patients underwent the non-intervention phase first, followed by the intervention phase. In the four- or six-week intervention phase, participants underwent twelve 20-minute sessions of gait rehabilitation using the GaitMaster4. Main outcome measures: We measured gait speed and timed up-and-go test. Results: No differences between the two groups were observed in the baseline clinical data. For the combined groups A and B, the maximum gait and timed up-and-go test speeds improved significantly only in the intervention phase ( P = 0.0001 and P = 0.003, respectively). The percentages of improvement from baseline at the end of GaitMaster training were 16.6% for the maximum gait speed and 8.3% for the timed up-and-go test. The effect size for GaitMaster4 training was 0.58 on the maximum gait speed and 0.43 on the timed up-and-go test. Conclusions: This pilot study showed that gait rehabilitation using the GaitMaster4 was a feasible training method for chronic stroke patients. Calculation of the sample size indicated that a sample size of 38 participants would be adequate to test a null hypothesis of nil benefit additional to routine rehabilitation for chronic stroke patients in a future randomized controlled trial.

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.
