Whiplash is defined as a sudden extension (backward movement of the neck) and flexion (forward movement of the neck) of the cervical spine. This type of trauma is also referred to as a cervical acceleration-deceleration (CAD) injury. Rear-end or side-impact motor vehicle collisions are the number one cause of whiplash with injury to the muscles, ligaments, tendons, joints, and discs of the cervical spine.
