Abstract
Survivors of stroke or other neurological conditions such as spinal cord injuries, traumatic brain injuries and Parkinson’s disease often struggle with mobility. To regain their motor functions, these patients are required to undergo physical therapy sessions. However, conventional physical therapy are labor intensive and lack of quantitative measures and biofeedback.

We are developing a novel intelligent robotic platform that enables patients to perform over-ground gait training at home or community rehab centers. The system consists of an omni-directional mobility platform, an active body weight support (BWS) unit, and a pelvic and trunk support and assist module. The omni-directional motion coupled with the pelvic support allows unrestricted natural trunk posture and pelvic motion. The adaptive shared controller enables several control modes depending on the patient condition. The system can provide stability, balance, and gait training. It can also provide perturbation, resistance, and error augmentation training methods to enhance training efficacy. A set of inertia measurement unit (IMU) sensors is used to measure the gait kinematics and provide quantitative measures of gait recovery. Surface electromyogram (EMG) sensors are used to monitor muscle condition and activation pattern. A functional electrical stimulation module can also be implemented on the system to provide simulations for patients with severe drop foot to enhance gait recovery.  In this talk, we will discuss the design, modeling, control and experimental results of the system.
