A system to rehabilitate stroke or traumatic brain injury survivors includes a brain machine interface that receives brain signals from the brain of a patient. The brain signals represent motor intent of the patient with respect to a hand of the patient that has impaired dexterous hand function due to neurological injury. A limb interface mounts to the hand of the patient. The limb interface detects feedback in the hand that results from the brain signals and helps to control the hand in accordance with the motor intent of the brain signals. The system also includes a processor operatively coupled to the brain machine interface and the limb interface. The processor is configured to synchronize the motor intent with the feedback to increase plasticity between sensory and motor areas of the brain to improve voluntary control of the hand, including dexterous hand functions such as multiple types of grasp.

This invention provides a rehabilitation training method, apparatus, device, and medium for gait symmetry optimization, specifically relating to the technical field of rehabilitation medical devices. This rehabilitation training method combines visual feedback walking with field-oriented gait analysis (FES), simultaneously collecting gait symmetry parameters during training to calculate gait symmetry; and also utilizes… f NIRS simultaneously monitors activation in the sensorimotor cortex, supplementary motor area, and premotor cortex, calculates the brain activation symmetry index, and dynamically adjusts at least one parameter of the gait training based on the deviation between the gait symmetry index and the brain activation symmetry index to achieve gait symmetry regulation. This combined intervention most effectively improves gait symmetry, and its mechanism is related to simultaneously enhancing activation in the affected side of the cortex and inhibiting excessive compensation in the healthy side, thereby optimizing the activation balance between the cerebral hemispheres. The positive correlation between gait improvement and brain activation symmetry provides evidence for the neural mechanism of this combined gait training modality.
