Auto Accident

 

WAD (Whiplash Associated Disorder) is the scientific term that describes the whiplash injury.

A 2005 published Canadian study of 7462 people who met criteria for whiplash injury and provided information regarding demographics and injury related symptoms concluded the following:

What is commonly referred to as whiplash associated disorders (WAD) is best appreciated as a syndrome extending well beyond what can be labeled as a neck injury. More research is needed for a better understanding of the underlying mechanisms involved so that treatment can be directed at the broad spectrum of the illness rather than focusing on finding a focal neck injury.

Auto accidents or motor vehicle collisions may result in soft tissue injuries. Extent of injury can depend on the collision force, collision direction, vehicle mass, vehicle design, vehicle safety design (seat belt, air bag, headrest) and the human body itself.

Frontal collisions are the most fatal type of the accidents, while the rear-end collision are responsible for most soft tissue injuries.

There are two possible injury mechanisms that occur, exactly at the same point during the whiplash:

  1. Muscle Injury
  2. Cervical Facet Injury

A single application of whiplash acceleration pulse can induce soft tissue–related and ligament-related alterations to cervical spine structures

Altered cervical spine structure may lead to decrease or reversal of cervical curve and accelerate the degenerative process or osetoarthritis in cervical spine.  

93% of whiplash patients improve with chiropractic care

A weight bearing (standing or sitting position) X-ray study of the neck (cervical spine) can provide an objective measurement for cervical curvature and the means to evaluate the extent or absence of spinal decay or osteoarthritis

Spinal decay or osteoarthritis that is commonly referred as “arthritis” is a contributing factor in progressive chronic neck pain. This contributes to the progressive reduction of movement of the neck (cervical ranges of motion) that can be measured objectively. .

Range of motion (ROM) of the cervical spine is an indispensable tool in the diagnosis and assessment of whiplash-associated disorders (WAD)

Range of cervical motion was reduced in persons with persistent whiplash-associated disorders
