Cervical acceleration-deceleration (CAD) syndrome, commonly known as whiplash, occurs when a person's head is yanked backward and then forward as the result of a sudden impact, usually when their car is rear-ended. This results in trauma to the spine, which can manifest itself as pain, numbness, tingling, or weakness in the neck, back, and shoulder areas. Coordination, balance, and even mental outlook can also be affected. We can help!
