Motor Vehicle Accidents: 'Whiplash Associated Disorders'
“40% of Whiplash injuries have persisting symptoms up to 15 years following the initial accident.”
Motor Vehicle Accidents involve any collision between a vehicle and a driver, passenger, motorcyclist, pedestrian, or bicyclist. Rear end collisions occur most commonly, followed by a side collision and lastly head-on collisions.
In Canada, it is estimated that the cost of road traffic collisions is $25 billion per year - this includes both structural damages and healthcare costs.
A biopsychosocial model should be used when treating MVA injuries. This allows us to consider the biological, psychological, and social factors which impact patients following complex injuries.
Healthcare providers, including physiotherapists, utilize this model to treat chronic pain as it helps address social and psychological factors that may negatively impact patients well-being following physical injury.
Neck pain, radiating, and headaches are the most commonly reported injuries following a MVA. After a MVA, 62% of vehicle occupants develop neck pain, often classified as Whiplash. Common symptoms of an acute Whiplash injury include:
Neck pain / Stiffness
Headaches
Shoulder / Arm Pain
Vision, Balance, Concentration, or Sleep Problems
Can lead to Fatigue
Whiplash can be defined as injury following sudden acceleration or deceleration of the neck. The initial impact of a MVA can result in bony / soft-tissue injuries, which, in turn, may lead to a variety of clinical manifestations called ‘Whiplash Associated Disorders’ (WAD).
When clients seek physiotherapy treatment following a MVA, their injury is classified according to the WAD system.
WAD classifications in Alberta range from Grade I to Grade IV, increasing in severity and associated signs and symptoms.
This system incorporates the biopsychosocial model as it considers individual biological, psychological, and social factors, including coping mechanisms and access to supports.
WAD I : includes neck symptoms with no physical signs of injury.
WAD II : includes neck symptoms and musculoskeletal signs.
WAD III : includes neck symptoms and neurological signs.
WAD IV : includes fractures or dislocation.
