Normal cervical spine rotation range has an upper limit of how many degrees?

• A. 0-30°
• B. 0-50°
• C. 0-90°
• D. 0-70°

Answer: (D)

Rotation of the neck is dominated by the upper cervical joints, especially the atlantoaxial region, with additional contribution from the lower cervical levels. In healthy adults, the ceiling for rotation to one side is about 70 degrees. This upper limit reflects the natural constraints of the ligaments, facet orientations, and surrounding soft tissues that allow a wide turning motion while preventing excessive strain. When you assess this motion, you typically have the patient seated, measure with a goniometer or inclinometer, and feel a firm end point as motion can’t be taken further without displacing tissues. Values around 70 degrees per side are considered normal, whereas noticeably less would indicate restriction, and a value near 90 degrees would exceed what’s normally available in a healthy neck.
