Among the most common of car accident injuries, whiplash is suffered by nearly one million Americans each year. Caused by the head being snapped unexpectedly in one direction, whiplash affects the vertebrae and surrounding tissues of the neck and back and aren’t due to any physical contact made to the area.

A rear collision is the likeliest cause for whiplash, but any distortion or hyperextension of the muscles and tissue in this area can lead to whiplash. Because it does not result in visible damage, such as abrasions or bruises, there has been some difficulty in the past in recognizing and treating whiplash.

Following the largest and most concentrated research done regarding whiplash, whiplash injuries were dividing into five categories that range from 0 to 4. Classified under the Quebec Task Force (QTF) system, whiplash categories are based on the presence and severity of various signs that include musculoskeletal and neurological damage, which many practitioners designate via Roman numerals.

Category of Grade II of whiplash occurs in the form of neck pain, stiffness, and/or tenderness. The patient will also suffer from a decreased range of motion.

What Are the Different Category Differences for Whiplash?

As defined by the Quebec Task Force, the clinical symptoms for whiplash are categorized into five grades. Where musculoskeletal signs are indicated, they include a decreased range of motion and a localized tenderness. Neurological signs are a decreased or lack of deep tendon reflexes along with sensory deficits and a general feeling of weakness. For all grades, the patient may experience deafness, dizziness, a headache, memory loss, or a ringing in the ears.

II Neck pain accompanied by musculoskeletal signs.

III Neck pain accompanied by neurological signs.

IV Neck pain and a fracture or dislocation.
