Chiropractic and Whiplash

Whiplash associated disorders (WAD) are common injuries of the neck caused by a rapid distortion of the cervical vertebrae. Such distortion occurs when the head undergoes a sudden stop while moving at speed, jarring the muscles and ligaments of the neck, which move forwards and backwards quickly. Whiplash is most typically associated with motor vehicle accidents but may also occur in sporting events (the often brutal stop tackles in football spring to mind) and falls from bicycles, chairs and horses.

The adult human head weighs about 10lbs, which, at rest, is comfortably supported by the bones and muscles of the neck. However, rapid movement backward and forward puts a much larger load on the cervical vertebrae and ligaments holding them in place. The anterior longitudinal ligament that runs down the back of the spine is particularly at risk of stretching or tearing during a rapid collision.

The signs and symptoms of whiplash associated disorders range from mild neck pain for a few days after the injury to headaches, arm pain and long-term restricted movement of the neck. Studies have shown that whiplash injuries can also constrict blood flow to the brain, leading to light-headedness, poor concentration and fatigue.

Since 1995, the Québec Task Force (QTF) scale has been widely used to assess the severity of WAD and how they should be treated. Their grading system is as follows:

Grade  Classification

0  – No complaint about the neck. No physical signs
I  – Neck complaint of pain, stiffness or tenderness only. No physical signs
II – Neck complaint and musculoskeletal signs. Musculoskeletal signs include decreased range of motion and point tenderness
III – Neck complaint and neurological signs. Neurological signs include decreased or absent deep tendon reflexes, weakness and sensory deficits
IV – Neck complaint and fracture or dislocation

In addition to grading the injury based on your symptoms, a chiropractor can assess the injury by performing a thorough examination, palpating the affected area and observing your neck movement and any associated pain.

The recommended chiropractic treatment will depend on the severity of the injury, but common actions include chiropractic adjustments, at home therapies and a specific program of exercises to gently regain the full range of neck movement. A bag of frozen peas held against the neck for short periods is a good stop-gap treatment for moderate neck pain if you have to wait for an appointment.

Grade IV whiplash is a serious injury and your chiropractor can refer you to a specialist for treatment. This will at minimum consist of several months of neck immobilization and possibly surgery. Most whiplash injuries are, much less serious than this and are more likely to be a cause of pain and discomfort than a true medical emergency. Though, as anyone who has suffered with WAD will tell you, the distress associated with ongoing neck pain and stiffness can have a substantial impact on daily life, and it is well worth getting checked over by a chiropractor if you experience any signs of whiplash in order to reduce your healing time and reduce the chance of future neck complaints.
