Normal neck rotation ROM is approximately which degree?

• A. 70-90 degrees
• B. 20-40 degrees
• C. 100-110 degrees
• D. 0-10 degrees

Answer: (A)

Normal neck rotation refers to turning the head side to side around the vertical axis. In a healthy adult, you can rotate roughly 45 degrees to each side, giving a total rotation of about 70–90 degrees. The atlantoaxial joint (between the first two cervical vertebrae) does most of this work, with the rest contributed by the other cervical levels, so the overall range lands in the 70–90 degree window. The other options fall outside the typical adult range: 20–40 degrees is too little, 0–10 degrees implies severe restriction, and 100–110 degrees would exceed normal capacity.
