The Research Of Human-computer Interaction System And Rehabilitation Evaluation Methods Of Upper Extremity Exoskeleton Rehabilitation Robot

Upper limb paralysis caused by cerebral apoplexy is a common disease, and the incidence presents increasing trend year by year. In clinical therapy, one physiotherapist can only give one patient physical therapy at once to make the recovery of the patient with upper limbs effectively. However, the effect of this way is susceptible to human factors and the standard to assess is uniformity. Therefore an efficient rehabilitation equipment is in badly need. The subject is on the basis of robot technology and the principle of rehabilitation proposes effective rehabilitation equipment, arm exoskeletons rehabilitation robot. The topic of article is about the research of arm exoskeletons rehabilitation training robot. Based on the previous research and the development of arm exoskeletons rehabilitation training robot, the paper sets a more in-depth research on rehabilitation evaluation method and the human-computer interaction system.In the first place, this paper is based on the research foundation for upper limb rehabilitation robot mechanism part and control part, completing the establishment and application of the rehabilitation robot active auxiliary control model. The model directly measures the force between patients and mechanical arm by the force sensor. Then according to the active auxiliary control model, this paper obtains the relationship of the force and joint velocity, controls the output torque of joints and realizes the stepper motor torque control, laying the foundation for the rehabilitation evaluation research.Secondly, this paper is based on the further study of human-computer interaction technology at home and abroad, building the overall function of human-computer interaction system framework model with the modular design ideas. And in the LabVIEW platform, this paper respectively achieve the user login module, user management module,patient management module, choice of control main board module, data communication module and the data management module, and on the development process it reflects the basic principle of "user-centric".Thirdly, according to the research of the existing rehabilitation evaluation method, this paper puts forward a based on AHP and fuzzy comprehensive evaluation method of rehabilitation evaluation. Rehabilitation evaluation model is established, and finally achieves local evaluation and overall rating. Under the base of this rehabilitation evaluationmodel, upper limbs rehabilitation robot rehabilitation evaluation software system is developed.Finally, the recovery actions of different training mode are studied by the exoskeleton upper limb rehabilitation robots and human-computer interaction system. The experiment verifies the reliability of the upper and lower position machine communication and the feasibility of rehabilitation evaluation methods. And the rehabilitation evaluation model is applied to the experiment analysis, tested the feasibility and practicability about the model.
