Design Of The Surface EMG Detection And Neuromuscular Electrical Stimulation And Muscle Strengthening Effect Study

Neuromuscular electrical stimulation has become a relatively mature rehabilitation measures because of its safety and effectiveness. It can maximize the retention of residual muscle morphology and function. It Can also be targeted to strengthen the muscles, strengthen coordination of muscle and alleviate fatigue. Surface EMG detection technology has evolved from the simple analysis of neuromuscular electrical characteristics to become a research based on biofeedback, The principle of Surface EMG detection is that the collected signals control the neuromuscular electrical stimulation. If EMG is not expected, stimulate the relevant muscle.This paper designed a neuromuscular electrical stimulation and sEMG acquisition instrument. The two modules are independent of each other, can use at the same time also can be used alone. Neuromuscular electrical stimulation circuit with constant current output design, which used microcomputer and D/A converter chip to control stimulation output. Surface electromyography detection circuit designed for multistage amplifier and multiple filtered, Output high common mode rejection ratio of the EMG signalThe validity of the instrument has been verified through the circuit experiments and clinical testing, circuit test including the constant current output circuit module of Neuromuscular electrical stimulation,Low pass filter module, high pass filtering module,50HZ notch circuit module and surface EMG detection module. Through the test can not only discover and solve possible problems, can also clearly verify whether each circuit module is expected worked. Clinical test is divided into two types of test, first, Neuromuscular electrical stimulation ’s somatosensory tests were completed with the cooperation of our lab’s students. Then we take electrical stimulation treatment On6hemiplegic patients were from The First Affiliated Hospital of Hunan University of Chinese Medicine. Proven neuromuscular electrical stimulation do have some enhancement to muscle strength and Muscle tension...
