| Abstract: | As a non invasive on line measurement, sEMG can reflect the status of muscle activity and muscle function accurately and objectively.Some sEMG Time frequency analysis techniques,especially the JASA(joint analysis of EMG spectrum and amplitude)analysis ,for evaluation of muscle fatigue in ergonomics and occupational field studies are introduced and evaluated in this paper.The sEMG signal analysis and the necessity for developing sEMG analysis techniques for field use in ergonomics are also briefly discussed. |
