Evaluation of Paraspinal Muscle Epimuscular Fat in Subjects With Low Back Pain in a Tertiary Care Setting

EF accumulation correlates significantly with age, BMI, sex, and chronic LBP severity, with a predilection for lower lumbar levels suggestive of biomechanical adaptation. These findings highlight EF as a potential biomarker and therapeutic target. Interventions aimed at EF reduction may enhance spinal stability and alleviate symptoms. Further longitudinal studies are warranted to validate these associations.
