%X In order to compare the lumbar muscle surface electromyography signal characteristics induced by Biering-sorensen and Ito-Shirado testing, 10 normal volunteers took part in the experiment, both L2~L3 and L5~S1 surface electromyographic signals were collected and then analyzed by recurrence quantification, spectrum and Lempel-Ziv complexity methods. The results showed that both signal complexity and mean power frequency increased while Determ% decreased linearly during loading. Multiple analysis of variance showed both load method and electrode composition could influence the slope of signal parameters mentioned above. The results suggested Biering-sorensen testing was more influential on signal characteristics than Ito-Shirado testing and electrode composition should also be considered when lumbar muscle function was tested.
