Research interests include conducting diagnosis, passive and active movement training, and outcome evaluations of sensorimotor impairments in stroke survivors and children with cerebral palsy using custom rehabilitation protocols and intelligent rehabilitation devices, investigation of reflex and nonreflex factors contributing to movement impairments and spasticity at the multi-joint, single-joint, and muscle fascicle and tendon levels, investigation of musculoskeletal injury mechanisms, compensatory mechanisms post injury, and rehabilitation and prevention of injuries. Furthermore, strong effort is made to translate research from lab to new rehabilitation protocols to improve treatment of injuries/impairments in clinical practice. He has published more than 130 peer-reviwed journal articles.



Project Description 1: Multi-Joint/DOFs Diagnosis and Treatment of Neurologically Impaired Arms

This project provides a robot-aided diagnosis and passive-active arm motor and sensory rehabilitation post stroke. The objectives are threefold: (1) quantify the progression of neuromechanical properties throughout the upper extremity during recovery from stroke, (2) address allocation of therapy resources between the arm and hand, and (3) examine the benefits of combining passive stretching with active movement training.  It captures the timeline for the advent of specific complications such as spasticity in the different joints and the extent to which they change over time and provides a guide for treatment. It investigates and assesses rehabilitation paradigms for targeting the multiple joints in the arm and/or the multiple fingers of the hand. Passive stretching and its interactions with active movement therapy are investigated. The multi-joint IntelliArm rehabilitation robot is capable of controlling and measuring the shoulder, elbow and wrist simultaneously in order to carry out multi-joint sensorimotor characterizations, forceful stretching, and robot-guided active movement training. The hand rehabilitation robot actuates each digit, allowing for stretching and movement assistance customized for each subject. Subacute stroke survivors participate in a blinded, controlled longitudinal intervention trial. Outcome evaluations in stroke survivors capture changes both in clinical measures of upper extremity performance and in neuromechanical properties. The study seeks to provide important data for deciding how best to devote limited resources to therapy. 


Project 2: Rehabilitation of Lower Limb Injuries or neurological disorders through Novel Offaxis Stepping Training

Although primary knee motions occur in knee flexion/extension, traumatic knee injuries and knee osteoarthritis (OA) are mostly caused by excessive off-axis loadings (frontal plane knee abduction/adduction and/or axial plane tibial rotation loadings). Similarly, the development and progression of knee injuries/OA are associated with excessive off-axis loadings. There has been a lack of rehabilitation protocols and devices to diagnose specific off-axis loadings associated with knee injuries/OA, followed by rehabilitation training of off-axis neuromuscular control and reducing excessive off-axis joint loads in clinical practice. We develop multi-axis stepping training and evaluation system and conduct offaxis neuromuscular rehabilitation training, which assesses multi-axis sensorimotor impairments, provides subject-specific real-time feedback on controlling excessive off-axis knee joint loads, and guides patients to improve off-axis sensory-motor performance during functional stepping movements.
