A surface electromyogram signal processing method and apparatus, and a wearable device, which relate to the technical field of intelligent wearable devices. The surface electromyogram signal processing method comprises: acquiring a surface electromyogram signal (101); importing the surface electromyogram signal into a kernel function for equidistant integration so as to obtain a determination signal (102); and when the determination signal is greater than a predetermined threshold value, determining that the surface electromyogram signal corresponding to the determination signal is in an action stage. By means of the described method, a surface electromyogram signal may first be processed on the basis of a kernel function, a determination signal may be obtained after equidistant integration, and it may be determined according to the determination signal whether the surface electromyogram signal is in an action stage or not, thereby reducing the dependence of the detection of an action stage on the setting of a threshold value, and improving the accuracy of the detection of an action stage.
