Extension is a movement that increases the angle between two body parts. In the spine, Extension usually means bending backward, such as arching the low back or looking up with the neck. It is commonly used in physical exams, rehabilitation, imaging tests, and surgical planning. Clinicians often discuss Extension together with flexion (bending forward) to describe how the spine moves and where symptoms change.
