The 7 vertebrae of the neck normally combine to form a 35-45 degree curve called the cervical lordosis. Biomechanical studies have shown that during a rear-end collision the torso is forced back into the seat and at the same time moves upward causing the lower cervical vertebrae to move into hyperextension while the upper cervical vertebrae flex forward. It is believed that it is during this time that injury occurs in the neck as the muscles, tendons, and ligaments are being strained to hold the vertebrae against opposing forces.
Chiropractors are trained to diagnosis and treat many of the injuries that are typically associated with whiplash. Your chiropractor will perform a thorough history and physical examination, may request x-rays or other imaging if necessary, will provide treatment to the soft tissues and joints as necessary, and will teach you proper home care for your injuries. Treatment can last anywhere from a few weeks to a few months depending on the severity of injury.
