Overview
This project will develop a wearable rehabilitation robot suitable for in-bed acute stage rehabilitation. It involves robot-guided motor relearning, passive and active motor-sensory rehabilitation early in the acute stage post-TBI including patients who are paralyzed with no motor output. The early acute TBI rehabilitation device will be evaluated in this clinical trial.
Description
Early after TBI, patients often have significant sensorimotor impairment. There is heightened neural excitability, which may be used to facilitate recovery in the acute phase post stroke. However, there has been a lack of effective and practical protocols and devices for early intensive sensorimotor therapy. The proposed randomized clinical trial using a wearable rehabilitation robot, muscle electromyography (EMG), and/or potentially brain electroencephalogram (EEG) signal seeks to provide early intensive sensorimotor training facilitated by real-time audiovisual and haptic feedback, intelligent stretching and sensory stimulation, active movement training through motivating movement games to promote neuroplasticity and reduce sensorimotor impairments. For acute TBI survivors who cannot generate any motor output yet, EMG or EEG may be used to detect the earliest re-emerging motor control signal and the robot can be used to provide demo and feedback of the intended movement.
