Let’s make it little bit clearer. Consider the mechanism first. We will begin with details about rear ended collisions. The exact injury mechanism that causes whiplash injuries is a forceful sudden hyperextension of neck (backward bending) followed by the hyperflexion (forward bending) of the neck (cervical spine), mostly spraining the ligaments (Nuchal ligaments, Anterior Longitudinal Ligaments etc.).
The lower neck spine is injured in hyperextension when the spine forms an S-shaped curve. Further, this occurs in the first whiplash phase before the neck is fully extended.
There is a bi-phasic or bidirectional motion response of the cervical spine to whiplash trauma. In the first phase, the spine forms an S-shaped curve with flexion at the upper levels of neck spine and hyper-extension at the lower levels of neck spine. In the second phase, all levels of the cervical spine were extended, and the head reached its maximum extension. The occurrence of frontal injuries in the lower levels in the first phase was confirmed by functional radiography, flexibility tests and imaging modalities. The excessive stretching due to impact on the capsular ligaments was observed at C6-C7 level during the initial S-shaped phase of whiplash. Along with that, the maximum elongation of the vertebral artery happens during the S-shape phase of whiplash.
Most people mistakenly think that it is sprain, strain or tenderness. However, identifying the mechanism of the injury and the structures involved in causing pain is crucial for choosing the right treatment process.
The excessive stretching of the vertebral artery (blood vessel of the neck supplying brain tissues) and several capsular ligaments were scientifically monitored during the trauma using specially designed transducers.
At higher trauma accelerations during the final phase of neck movement (forward bending), there is a tendency for the injuries to occur at the upper levels of the cervical spine. At Chinook Rehab Centre our physiotherapist’s findings during the initial assessments provide patients with true understanding of whiplash injury (WAD I, WAD II, WAD III & WAD IV) and help them in improving their wellbeing and educate on prevention of similar injuries in the future. Even a low-velocity motor vehicle crash can cause whiplash-associated disorders (WAD) that often leads to severe and chronic neck disorders.
The kinematics and muscular responses on the neck during frontal-side collisions have hardly been investigated. At the same time, in rear-end collisions, drivers were observed to have shown a higher WAD risk than front seat passengers.
Studies have shown that the severity of the injury will be lessen when one can expect the vehicle coming from behind as compared to a totally unexpected collision from behind because the neck muscles automatically get activated when one sees an oncoming vehicle through the rear-view mirror.
