Lumbar Spine Musculoskeletal Physiology and Biomechanics During Simulated Military Operations
Abstract
This study evaluated the relationship between 3D geometry of the lumbar spine, under different positions, and the pathophysiology of the intervertebral disc and lumbar trunk muscles. 43 Marines were scanned using upright MRI in operationally relevant loading conditions with minimum operational load, 39 of these Marines were also scanned in a high-resolution MRI to assess muscle and disc physiology. Local changes in posture were found in sitting and prone on elbows positions. A caudal increase in fat fraction of the multifidus was observed. No significant correlations were found between disc injury, low back pain, and muscle pathophysiology. Erector spinae fractional anisotropy was found to be a significant predictor of lumbar posture;increased fractional anisotropy predicts straighter, forward leaning posture.
