Abstract
As part of this study, an ankle rehabilitation device was developed for patients suffering from motor disorders caused by incomplete spinal cord injury (ISCI), stroke, or cerebral palsy. First, the research models and dynamic equations of the device were considered. Secondly, the prototype ankle rehabilitation device is made of PLA plastic and uses linear actuators to simulate outward and inward flexion exercises (dorsiflexion and plantar flexion) for the patient. The advantages of the device are its simple design, low cost, and the possibility of installation on recovery equipment. The device can work quickly in experiments, in addition, the rehabilitation robot can work stably and is convenient to use for patients.
