University of Minnesota Technology Overview
A new robotic system for wrist joint proprioception provides both assessment of function and rehabilitation training all in the same device. The device not only measures a user’s ability to sense wrist position and detect various degrees of movement, but also provides discrete and continuous motion rehabilitation training exercises that can be tailored to each user’s ability. The software provides users with visual, tactile and haptic feedback and provides clinicians with an objective assessment of the subject’s wrist proprioception ability and rehabilitation progress.
The handle of the device operates along the three degrees of freedom of movement of the wrist: flexion-extension, abduction-adduction and pronation-supination. In the assessment mode, the device delivers forces to the wrist along these axes and assesses the user’s ability to sense these forces, while in training mode users can move the unit themselves along the same three axes to perform various tasks.
The technology was found to reliably measure wrist joint acuity in order to accurately assess proprioceptive status and level of function/dysfunction, and the device is expected to deliver similar encouraging results in improving efficiency and efficacy of rehabilitation. Therapists can remotely access the device’s software to see results and program the therapy, allowing patients to use the device at home to reduce the cost and time associated with multiple in-person office visits.
