Comparison of Combined Motor Control Training and Isolated Extensor Strengthening Versus General Exercise on Lumbar Paraspinal Muscle Health and Associations With Patient-Reported Outcome Measures in Chronic Low Back Pain Patients: A Randomized Controlled Trial.

Interestingly, however, when performing analysis separately for each spinal level (e.g., middle 3 slices for each spinal level) the authors reported a significant increase in MF CSA at L3, L4 and L5 in the general strength and conditioning group at 6-months, and a significant decrease in MF CSA at L1 in the motor control group at 3-months, which was nearly significant ( P = 0.05) at L2 as well.
