Abstract: The surface electromyography (sEMG) is the noninvasive method which can record and measure the changes of local muscle activities. The sEMG's amplitude and frequence signal will change with muscular movement. sEMG application in present study on muscle fatigue is a reliable predictor of muscle functional level. The researches on the sEMG signals changes of limb muscles of hemiplegic patients will take a important role in providing scientific evidence for the neural rehabilitation training after stroke.

Key words: surface electromyography (SEMG), muscle fatigue, stroke, review
