User and expert feedback for lower-extremity robotic exercise prototype

A mobile platform-based rehabilitation robotic system with a lower-extremity exoskeleton was developed for people with disabilities to allow them to perform therapeutic exercises and to support daily living activities. The system consists of a weight support module, a locomotion module, and an exoskeleton module for lower extremities. We collected the needs and feedback of users and clinical experts from a previously developed system. In this paper, we review important points for the design of a system for people with motor impairments of the lower extremities. This system is an example of a human-in-the-loop system. We focused on the physical interaction between the human subject and system. As a pilot study, we checked the pressure of the harness supporting the weight of the subject.
