There might be a link between lumbar dysfunction and fat infiltration in lumbar multifidus muscles in low back pain

Low back pain (LBP) has a lifetime prevalence of up to 84% rendering it's high incidence rate. Chronic low back pain (CLBP) is indicated as persisting pain for more than 12 weeks. Lumbar multifidus muscles (LMM) are crucial for spinal motion and stability. Fat infiltration in LMM often leads to LBP. An increasing fat infiltration of LMM may induce lumbar dysfunction. This correlation between the severity of lumbar dysfunction and the severity of fat infiltration of LMM has been depicted in this study.

A total of 42 patients with acute or chronic LBP were enrolled in this cross-sectional study. Three criteria for the fat accumulation in LMM were used to visually rate and grade their MRI findings: Grade 0 (0–10%), Grade 1 (10–50%) and Grade 2 (>50%). Several aspects like the lumbar sagittal range of motion, dynamic upright and seated posture control, sagittal movement control, body awareness and self-assessed functional disability were calculated to find out the patient's low back dysfunction.

The principal result of this study was that increased severity of fat infiltration in the lumbar multifidus muscles was correlated significantly with the decreased range of motion of lumbar flexion (p=0.032). No important correlation was observed between the severity of fat infiltration in LMM and impaired movement control, posture control, body awareness or self-assessed functional disability.

This study was the first one to assess the association between the severity of fat infiltration in LMM and the severity of lumbar dysfunction. The mechanisms causing fat infiltration of LMM and its relation to spinal function will be much clear with the help of outcomes of this study.

Future studies should portray whether specific treatment methods are effective in reducing or preventing fat infiltration of LMM.
