Rehabilitation medicine focuses on the clinical rehabilitation problems of functional impairments caused by neurological disorders. The key research fields include neurological rehabilitation, motor rehabilitation, audiovisual rehabilitation, speech rehabilitation, psychiatric rehabilitation, occupational rehabilitation, etc. We research the development of intelligent assessment techniques for upper and lower limb movement patterns, gait balance capability, as well as the assessment of emotional and mental states and auditory abilities. We also explore mechanisms of neural regulation and the cognitive-motor interaction to investigate further advanced intelligent rehabilitation methods, such as neural regulation therapy, sensory function reconstruction, and motor function recovery. We develop intelligent human-machine interaction strategies that have been applied in innovative brain-computer interface devices for emotional and auditory function diagnostics, BCI-controlled rehabilitation training systems for the additional limb, and BCI-controlled hybrid actuated exoskeleton systems for gait assistance.
