C hronic low back pain (LBP)is very popular among people. In order to assist in the treatment of this pain, surface electromyography (SEMG) is applied to the treatment. Based on SEMG, the dynamic SEMG topography is a new objective and quantitative assessment tool toassess the LBP level.Thus, how to analyze the prognostic value of the SEMG topography for identifying the patients? LBP level during rehabilitation more effectively is significant. 38 chronic non-specific LBP patients without previous history of acute LBP and 43 healthy subjects were recruited. They were required to accomplish the lumbar flexion and extension movement and the SEMG signal could be obtained from the relevant lumbar muscles. According to the patients? rehabilitation level after physiotherapy, the patients were divided into ?responding? and ?non-responding? groups. The former?s recoverywas good whereas the latter?swas not. Through applying the root-mean-square difference (RMSD) to the quantitative analysis on the time-varying SEMG topography, the LBP level of the ?responding? group could be differentiated from the ?non-responding? group because the RMSD of RA and RW at lumbar flexion and extension in the ?non-responding? group were significantly higher than those in the ?responding? group (p<0.05). Meanwhile, the discrimination accuracy of these two groups could also be tested by using the ROC curve. The areas under ROC curves of RMSD RA and RMSD RW were greater than 0.7 (p<0.05). In conclusion, it is effective and useful to assess the LBP level through the RMSD RA and RMSD RW value from the SEMG topography.
