Lumbar Extensor Muscle Size and Isometric Muscle Strength in Women with Symptomatic Lumbar Degenerative Diseases.

CONCLUSIONS: In women with LDD, LEM sizes of the upper lumbar levels (L1-4) were larger than those of the lower levels (L4-S1) and were positively associated with muscle strength. The upper lumbar levels in patients with LDDs appear to play a compensatory role when degenerative lesions are present in the lower lumbar levels. PMID: 30213179 [PubMed]
