Fig. 4From: Correlation between lumbar dysfunction and fat infiltration in lumbar multifidus muscles in patients with low back painBoxplots showing the association between the severity of fat infiltration (Grade 0, 1 and 2) and lumbar flexion, movement control and posture control. Only decreased lumbar flexion correlated significantly with increased severity of fat infiltration in multifidus muscles. No significant association was found between the severity of fat infiltration and impaired movement control or impaired posture controlBack to article page
