Objective To explore the changes of surface electromyography (sEMG) signal during gait cycle and its various phases of the lower limbs of stroke patients, to guide targeted gait rehabilitation training for stroke patients. Methods From January to June, 2018, 20 stroke patients and 20 healthy subjects were involved in this study. All the subjects were asked to walk naturally. At the same time, the sEMG signals of bilateral tibialis anterior (TA), rectus femoris (RF), gastrocnemius medial (GM) and biceps femoris (BF) were recorded by Noraxon wireless surface electromyography acquisition system. Results The electromyographic activities of TA, RF, GM and BF of healthy subjects changed with the activity and static periodicity during gait cycle, and the muscles of the same name alternated, and they were disturbed in stroke patients. Conclusion The surface electromyography can reflect the gait-related muscle damage in stroke patients and can be used to guide gait rehabilitation training.
