Wearable Device Design For Accurate Hand Rehabilitation Of Stroke Patients

Stroke Stroke disease is a high incidence of hand disorders.Every year,thousands of people suffer from hand motor dysfunction due to stroke disease.Hand wearable devices are an important tool for hand motor dysfunction rehabilitation.Through two years of investigation and research,there are many problems with the products used to restore hand dysfunction.This paper designs a rehabilitation manipulator that can help stroke patients recover hand function.The fingers of patients can be trained within the normal range of finger movement driven by the driving mechanism,so as to gradually improve the quality of life.After analyzing the existing products and research status at home and abroad,the motion mode and range of human hand skeleton joints are firstly studied and analyzed.The AHP hierarchy method was used to compare the weights of the factors affecting the patients' use of the rehabilitation manipulator.The problem of large volume of rehabilitation manipulator is optimized.Hand in patients with cerebral apoplexy by the principle of reverse engineering 3 d scanning,data of scanning the patient's hand model and inductive analysis,find obvious difference characteristic,analyse numerical characters of the hand,looking for differences in hands,the parameterized model is established through the Grasshopper platform,set up personalized numerical,wear parts for stroke hand wear product value adjustment,change the model configuration,customization model in order to achieve the purpose,to solve in the process of exercise rehabilitation finger parts wear uncomfortable and inconvenient use of the information,to achieve the purpose of accurate training and accurate recovery.By combining parametric modeling with the principle of reverse engineering,professional physicians can eliminate the steps of 3d hand scanning,point cloud processing,model surface reconstruction and model entity reconstruction in the follow-up work to improve work efficiency.Then the actual wearing is verified to verify the feasibility of the parametric model design applied to the finger part of the rehabilitation manipulator.The fuzzy comprehensive evaluation method is used to evaluate the scheme and select the most suitable scheme for the manipulator.Through the parameterized customized model,the rehabilitation manipulator fits the finger surface more closely,fully drives the finger to carry on the rehabilitation movement,and achieves the function of accurate rehabilitation and training.
