Injury sustained in any activity either sports related or an accident can be differentiated into two types: Acute and Chronic.
Acute injury is defined as an injury sustained suddenly during an activity e.g. an ankle sprain, lower back strain or a fractured limb. Acute injury is associated with some characteristic features including
Whiplash is described as an injury to the neck due to sudden rapid forward and backward motion resulting from trauma; which is car accident in most of the cases, but may also occur due to falls, sport related injuries or knock over head by a heavy object.
This sudden over-extension of the head and neck impacts the muscles and ligaments causing stretching and probable tearing of neck tissues. Whiplash may also involve tearing, bulging or rupture of the vertebral discs or may also cause vertebral dislocation. It may also affect the spinal cord and nerve roots passing through the space between vertebras, which may develop irritation or stretch or get pinched because of the reduced gap in between the vertebra.
