Neck pain often arises from tight neck muscles that pull the neck vertebrae slightly out of alignment, called subluxation, which then impinge on sensory nerves entering the spine between these vertebrae. These sensory nerves relay that information back to the brain setting off the alarm in the form of pain.
Wrist Bending. Forward bending of your wrist is called flexion. This motion is needed for daily activities such as styling your hair, writing, getting dressed, using a screwdriver and lifting heavy objects. Normal wrist flexion is approximately 70 to 90 degrees.
Rotation. Rotation is the movement which we use to look over our shoulder or look back. The movement is equal on either side. Normal range of motion of cervical spine is. 1  Flexion â 80 to 90 degrees. 2  Extension â 70 degrees. 3  Lateral flexion â 20 to 45 degrees on both sides.4  Rotation â 90Â° of rotation to both sides.ormal flexion to hyperextension at the atlanto-occipital joint range is 15 to 20 degrees. Rest is contributed by lower vertebrae. Rotation and lateral flexion between the occiput and atlas are not possible due to the depth of the atlantal sockets. These movements occur on atlanto axial joint [C1-C2].
