Low back muscle size, disability and pain intensity

Can you predict low back disability and pain intensity from the paraspinal muscle cross-sectional area?

Commonly, the multifidus and erector spinae muscles collectively are referred to as the paraspinal (PS) muscles. The PS muscles have an important role in movement and control of the spine, and thus could be a potential contributor to low back pain (LBP) and disability. 

The aim of this study was to find out the relationship between the cross-sectional area (CSA) of the PS muscle and LBP and disability over a 1 year follow-up period.

This study found an inverse relationship between CSA of the lumbar PS muscle and low back disability but not pain intensity.
