From: Clinical characteristics of geriatric patients with non-specific chronic low back pain
Correlation between skeletal muscle mass and spinal sagittal alignment. Lower muscle mass in both legs and trunk was negatively correlated with PT, whereas only trunk muscle mass was negatively correlated with SVA. Muscle mass in both legs and trunk was negatively correlated with PI-LL; however, trunk muscle mass had stronger correlation with PI-LL compared with lower extremity muscle mass. The total number of plots was obtained by summing 203 cases in the CLBP group and 683 cases in the control group excluding 512 cases with LBP. PT: pelvic tilt, SVA: sagittal vertical axis, LL: lumbar lordosis, PI: pelvic incidence, PI-LL: PI minus LL.
