The relationship between System Usage and SCI Rehabilitation. The system drives the rehabilitation robot to drive the patient’s limb movement by decoding the motor intention and provides feedback to the patients. The continuous motor state switching time of patients is an evaluation of the performance of the BCI paradigm. The descending control signals and the ascending sensory signals stimulate the spinal cord injury area. The motor state percent and the effective training revolutions can measure whether the descending control signal and the ascending sensory signal of the BCI can generate sufficient stimulation to the SCI area during training. The following portion is the schematic diagram of the system to stimulate the injured area of SCI patients. Motor state percent is used to evaluate the intensity of descending motor control signal in a single training. Effective training revolutions are employed to assess the intensity of ascending sensory signals. Continuous motor state switching time is used to evaluate the patient’s state of training using BCI system. The dash line represents the assessment. The solid lines represent signal correlation
