Research On Stroke Rehabilitation Equipment Based On Healthy Limb

In recent years,the number of stroke patients is growing at an amazing speed,this phenomenon occurs not only in China,but generally exists in all the world.Lots of people can not move their unilateral limb after stroke.Whether the patient can get the rehabilitation of stock in time plays a key role in reducing and alleviating the sequel.The rehabilitation of stork also determines the quality of patients' personal life.It is often difficult for stroke victims to recover hand,the the rehabilitation of hand means a lot to the patient.The stroke rehabilitation equipment was designed in this thesis for current situation.This equipment can help stoke patients do some rehabilitation exercise that based on doctor's order by themselves.This system can control the affected limbs by the data of flex sensors,the data acquisition and the gasbag control at the same time.When the data of flex sensors changed,MCU control the inflation/deflation of gasbag.Because of the upper limit of gasbag pressure chose a pressure sensor to control it.To make the efficiency of labor more remarkable,this system chose LCD to display.This system has multiple operating modes,exercise mode,game mode and test mode.Basic model of these is exercise mode,patient can see the the degree of stretching of fingers in time.Patients can only use one finger in game mode,when the angle of finger rising is big enough,the system plus one point.In test mode,patients can see the rehabilitation of themselves.Multi-mode design increases the interest of rehabilitation and the participation of patients.Using different method of sEMG analysis to evaluate the effectiveness of the equipment,such as time domain,frequency domain and time-frequency domain,analyzing the sEMG when hand made a fist or not.Then the result showed that the passive movement can exercised the muscle which were affected by stroke.
