Study On Household Gait Acquisition System For Stroke Patients Based On Inertial Sensors

With the aging of our country,the number of stroke patients is increasing day by day,and the problem of postoperative rehabilitation of stroke patients is becoming more and more serious.Our country's medical resources are limited,most of the stroke patients go to the hospital for rehabilitation training after operation,while occupying the medical resources,it also causes the burden to the patients who are unable to move,so it is necessary for the stroke patients to recover at home.Aiming at the rehabilitation status of stroke patients in China,this paper aims to design and research a set of gait acquisition system for stroke patients at home,so that patients can collect gait information at home,provide basis for rehabilitation guidance,and bring convenience to patients.In this study,inertial sensors are used to collect the gait information of patients' feet,the acceleration signal is corresponding to the gait period,and then Bluetooth technology is used to realize the wireless transmission of data.Finally,extreme value operation and MATLAB software is used to process and analyze the gait acceleration signal.The experimental results show that the gait signal acquisition system can effectively collect the gait acceleration signal of stroke patients,and the algorithm can also effectively identify the gait information,which successfully verifies the feasibility and effectiveness of the system.
