Description

Method for improving on-demand auxiliary rehabilitation training participation degree based on Bayesian optimization
Technical Field
The invention belongs to the technical field of rehabilitation robots, rehabilitation training and machine learning, and particularly relates to a method for improving on-demand auxiliary rehabilitation training participation based on Bayesian optimization.
Background
Stroke has become one of the major diseases threatening physical and mental health and life safety of human beings, and more than half of stroke patients have upper limb motor dysfunction which seriously affects their activities of daily life. The traditional upper limb rehabilitation therapy mode mainly depends on a rehabilitation therapist for manual auxiliary training, and the mode needs to consume a large amount of physical strength of the rehabilitation therapist and is difficult to accurately evaluate the rehabilitation state of a patient. With the development of the robot technology, the appearance of the rehabilitation robot provides a new way for rehabilitation therapy. The rehabilitation robot can assist a patient to carry out rehabilitation training without the on-site guidance of a rehabilitation therapist, and a large amount of labor cost is saved. In addition, the rehabilitation robot can accurately evaluate the rehabilitation state of the patient through various sensors, is beneficial to a rehabilitation therapist to make a subsequent treatment scheme for the patient, and has wide market application prospect.
The control strategy of the rehabilitation robot is one of the key factors influencing the rehabilitation treatment effect. In recent years, on-demand assist control strategies have become a research focus in this field. As the name suggests, the main idea of the on-demand auxiliary control strategy is that the rehabilitation robot provides the auxiliary torque required by the rehabilitation robot to complete the rehabilitation training task according to the rehabilitation requirement to be tested. The control strategy minimizes the auxiliary moment provided by the rehabilitation robot on the premise of ensuring that the rehabilitation training task is completed by the test, thereby maximizing the main moment provided by the test. Researches show that the repeated nature of rehabilitation training easily makes the tested person lose interest and feel bored, and an inappropriate auxiliary training strategy is very likely to make the tested person lose confidence, generate boring emotion for rehabilitation training and have extremely adverse effects on rehabilitation effect. Therefore, one of the research focuses on maintaining and improving the active participation of the subject in rehabilitation training. Studies have shown that maintaining active participation in subjects can improve the efficiency of rehabilitation. However, most of the existing rehabilitation robots only consider the movement performance of the subject to change an on-demand auxiliary strategy, lack a quantitative evaluation mechanism for the active participation degree of the subject, and cannot monitor the physiological and psychological state change of the subject in real time so as to know the change of the participation degree of the subject. There is also no effective mechanism for mobilizing the positivity of the subject, and the active participation and the input status of the subject cannot be guaranteed. In other words, the existing rehabilitation robot can not effectively guide the active participation of the tested person in the auxiliary training on the basis of force and motion, and can not feed back the tested state in real time and carry out targeted auxiliary strategy adjustment on demand. Therefore, the motor performance index and the motor participation index of the tested body are quantitatively evaluated at the same time, a machine learning method is combined to develop a strategy which can monitor the physiological and psychological states of the tested body in real time, and a personalized and optimal auxiliary strategy on demand is provided according to the change conditions of the motor performance and the motor participation of the tested body, so that the active input state of the tested body is ensured, nerves are effectively stimulated to effectively cause nerve function recombination, the training efficiency of the robot technology auxiliary rehabilitation is expected to be improved, and the method is also a key element for the rehabilitation robot to enter clinical application more quickly.
