Abstract:
Objective To explore the correlation between the moving angle of elbow joint and surface electromyogram signal(sEMG)activities of biceps and triceps.Methods The eigenvalue of sEMG during elbow joint moving under constant load were calculated with means of root mean square(RMS)and integrated electromyogram(iEMG)in time domain.Results The experimental results showed that both the chavacteristics of RMS and iEMG for biceps differed from those of triceps.The sEMG activities of biceps increased with the increment of elbow joint angle,while those from triceps reached to the maximum values when elbow joint angle was 90?.Furthermore,the sEMG activities of triceps at the elbow angle of 45? was similar with that when elbow angle was 135?.Conclusion The sEMG from biceps and triceps can reflect the moving angle of elbow joint under constant load.
