Normal neck side flexion ROM is approximately what degree?

• A. 20-45 degrees
• B. 60-90 degrees
• C. 0-10 degrees
• D. 90-120 degrees

Answer: (A)

Normal neck side bending (lateral flexion) is about 20 to 45 degrees on each side. This range reflects the typical mobility of the cervical spine allowing the head to tilt toward the shoulder without requiring large trunk movement. In healthy adults, end-range values usually fall around the 40‑degree mark, with some natural variation. Values outside this range aren’t considered normal: 0–10 degrees indicates restricted motion, while 60–90 degrees or 90–120 degrees would be greater than what’s expected for the cervical region and may suggest measurement error or hypermobility rather than typical, healthy ROM.
