Chronic low back pain (CLBP) has been reported to be associated with low back dysfunction with the characteristics of decreased cross-section area (CSA) of paraspinal muscles and increased adipose content. In our study, T2 value at L4/L5 multifidus muscle was significantly higher in LBP group than in HCs. The multifidus muscle is the most medial in the low back extensor group and has the maximum strain stress when spinal movement and balance maintenance, so it might easily cause the abnormality of the low back muscle group. T2 mapping could be a good predictor of detecting minimal variation of multifidus muscles.
