Video Transcript Whiplash occurs when the head is rapidly thrust backward and then forward, subjecting the cervical spine to extreme forces. It is medically known as cervical acceleration-deceleration syndrome. Whiplash can be caused by various high-impact events, ranging from falls to sports collisions, but it most commonly happens when a person is rear-ended in a motor vehicle accident. Initially, the accelerating seatback pushes against the person's back, which sends forces up the cervical spine, compressing it against the head. The torso is accelerated forward but the head is not because it has yet to contact the accelerating headrest. This causes the cervical spine to temporarily lose its C-shape lordosis curve and become an unnatural S-shape. These forces put extreme stress on the facet joints and intervertebral discs before the muscles have any chance to stabilize and protect the cervical spine. Then the head rotates backward and goes into extension before bouncing off the headrest and accelerating forward, whipping into full flexion.
