Flexion/Rotation Test for C0-C1 ROM
With the C-spine in axial extension (aka retraction, posterior chin glide), the athlete's chin is passively flexed, then rotated. Normal ROM would be between 30-35 degrees. At that point you'll feel an abrupt change in the quality of movement. That's where the motion reaches C2. If you look at the athlete's eye brows you can see there is a restriction. This is fairly common in combative & collision sports.
