基于功能性电刺激技术的脑卒中后手功能康复训练系统设计OA

Objective To design a hand function rehabilitation training system based on functional electrical stimulation(FES)technology to solve the problems of the traditional training system in limited motion patterns and real-time response and precision of the control system.Methods The hand function rehabilitation training system used an Arduino UNO R3 demo board as the core controller,and consisted of a wearable device,a passive motion training module and an electrical sti-mulator.The wearable device was equipped with a Flex Sensor bend sensor,a MPU6050 angle sensor,a Flexiforce thin-film pressure sensor,a SHT30 temperature and humidity sensor and a ST021 heating pad;the passive motion training module was composed of a SG90 servo motor and a connecting mechanism;the electrical stimulator based on three-axis independent adjust mechanism had a self-adaptive adjustment module as the core unit and two independent stimulating units.The software of the system was developed with the Android Studio platform and Java language.A hand musculoskeletal model was constructed using the open-source simulation platform(OpenSim),and the system designed was compared with the standard rehabilitation system of virtual rehabilitation simulation platform(RCareWorld)and proportional-integral-derivative(PID)controlled exoskeleton system so as to validate its effectiveness and reliability.Results The system designed featured passive and autonomous motion patterns,which was capable of activating hand muscles in post-stroke patients through electrical stimulation to enhance blood circulation,recording automatically detailed data for each exercise session to generate training reports and creating individualized rehabilitation schemes.Validation results showed the system designed effectively delayed patient fatigue progression through dynamic parameter adjustment and achieved superior muscle strength maintenance and motion performance when compared with RCareWorld's standard rehabilitation system and PID controlled exoskeleton system.Conclusion The hand rehabilitation training system proposed gains advantages in multi patterns and individualized adaptation,providing an efficient and feasible rehabilitation solution for hand function recovery in post-stroke patients.[Chinese Medical Equipment Journal,2026,47(1):21-27].
