Limb Rehabilitation Assisted Training System Based On Virtual Reality

As China gradually enters an aging society,the number of rehabilitation patients with poor mobility is increasing,the demand for physical rehabilitation is growing,and the challenges facing the physical rehabilitation field are becoming more and more prominent: the existing medical resources are difficult to meet the huge rehabilitation Patient needs,traditional limb rehabilitation training is boring and difficult for patients to adhere to;patients suffer from anxiety,depression and other psychological emotions due to limb dysfunction.Existing rehabilitation equipment has a rough interface and poor age,and poor interactive experience.In response to the national call for deepening innovative applications of virtual reality and alleviating the above-mentioned practical problems in the field of physical rehabilitation,this topic uses field surveys and in-depth interviews to analyze the characteristics and needs of target users,combined with sports to relearn traditional rehabilitation training Therapy,based on virtual reality technology,uses the Unity 3D engine to design and develop a set of personalized training content customization,feedback and evaluation intelligence,promote patient rehabilitation,and adjust the psychological and emotional system.This system is divided into a patient training subsystem and a rehabilitation subsystem customized subsystem.The patient training subsystem is divided into two functional modules: limb rehabilitation training module and psychological adjustment module.The limb rehabilitation training module guides the patients to complete the training actions in the form of fun games through the walls,records the joint data and the completion of the actions and feeds them back to the customized subsystem of the rehabilitation engineer;the psychological adjustment module uses crying catharsis therapy to provide patients with a natural immersion Scenes,patients shouting loudly can interact with specific elements of the scene to ease the psychological emotions of patients such as anxiety and depression due to physical dysfunction.The two modules of the patient training subsystem now include 2 limb rehabilitation training scenarios and 3 psychological rehabilitation scenarios.The rehabilitation subsystem customizes the subsystem.The rehabilitation division can set the patient training subsystem account password,enter and edit the patient’s basic information;can customize the rehabilitation content,customize the entry of rehabilitation actions,set rehabilitation training tasks and plans;can remotely receive patient-side training data,Check the accuracy of the joints of the training action,adjust the training speed and training difficulty and other functions.This system combines physical rehabilitation with psychological adjustment.The rehabilitation teacher can personally customize the rehabilitation training actions according to the specific conditions of different patients.The patients can independently train and train without the assistance of the rehabilitation teacher through the system’s guided feedback and other functions.During the period,timely test evaluation feedback,obtain training process data,the rehabilitation teacher can analyze the training situation of the patient,intelligently adjust the training plan,realize the one-to-many remote rehabilitation guidance of the rehabilitation teacher,improve the work efficiency of the rehabilitation teacher,facilitate patient training,ease The pressure of insufficient number of rehabilitation teachers.According to the evaluation of professional rehabilitation teachers and the pilot application and experiments of rehabilitation hospitals,the statistical data obtained show that the patients who received the rehabilitation assistance training of this system,the Fugl-Meyer limb motor function evaluation measurement score,Guokang posture and exercise evaluation measurement table score are traditional About 2 times of rehabilitation training patients,this system assists rehabilitation specialists to help patients return to daily life as soon as possible,improves the rehabilitation effect and efficiency,has broad application prospects in the field of physical rehabilitation,and also provides references for its application research in the field.
