Do MRI-derived muscle moment-arms in patients with chronic low back pain differ from healthy individuals? A comparative study

ConclusionsThere was a significant difference in muscle moment-arms of the lumbar spine's prime stabilizer (psoas) and primary locomotors (rectus abdominis and obliques) between LBP patients and healthy individuals. This difference in the moment-arms leads to altered compressive forces at intervertebral discs and may be one of the risk factors for LBP.
