Previous studies have reported increasing fat infiltration of paraspinal muscle especially intramyocellular lipids (IMCL) in multifidus muscle (Mm). The aim of this study was to longitudinally investigate the correlation between change of low back pain (LBP) and that of IMCL in Mm. The improvement ratio of LBP showed the correlation with change ratio of IMCL (r = 0.818, p < 0.001). Therefore, there were trend decreasing IMCL with improving LBP. It was suggested IMCL in Mm correlated with chronic LBP.
