What is the normal range for lumbar flexion?

• A. Approximately 60–80 degrees
• B. Approximately 40–60 degrees
• C. 70–90 degrees
• D. 100–120 degrees

Answer: (B)

Lumbar flexion ROM is how much the lower back can bend forward from a neutral spine, ideally measured so the motion comes mainly from the lumbar region. In most adults, the lumbar spine alone provides about 40–60 degrees of forward bending, with many clinicians citing roughly 50 degrees as typical. The other ranges listed are higher than what the lumbar spine can usually achieve by itself; they typically involve motion from the hips or thoracic spine, or reflect overall trunk flexion rather than pure lumbar motion. So, the normal range for lumbar flexion is about 40–60 degrees.
