Key Points

Chronic lumbago is linked to complex mechanisms affecting intervertebral discs and psoas muscles.
Hoop stress analysis shows up to 20 times body weight impact during lumbar flexion in patients.
Data from 1400 patients assessed factors like gender, weight, and bending postures on pain levels.
Results reveal that hoop stress at L4-L5 intervertebral disc is 1.3 times greater than at L3-L4.

Implication

Research analyzes hoop stress effects on psoas muscles in 1400 patients with chronic lumbago, suggesting a new pain index approach.
