The loss of upper limb function caused by spinal cord injury can be restored partly through functional electrical stimulation.By means of the analysis of the relationship between the movements and muscles of upper arm,correct recognition of upper arm movements by surface electromyography is the key to realize function restoration.six movements are set,as bending arm,straightening the arm,swaying outward horizontally,swaying inward horizontally,rotating outward vertically and rotating inward vertically,to record the surface electromyography of deltoid,biceps and triceps by three channels simultaneously,by using time domain and frequency domain method for picking up the characteristic value,recognizing through artificial neural network.The recognition rate is above 90%.It confirms that it's feasible to recognize upper limb movements by surface electromyography of deltoid,biceps and triceps,which lays a theoretical foundation that biological electrical signals control mechanical prosthesis and can realize the restoration of the function caused by spinal cord injury.
