acceleration-deceleration injury: injury resulting from a collision between a body part and another object or body part while both are in motion.
The most common injury resulting from car accidents is whiplash, accounting for 80 percent of all car crash injuries.Whiplash is considered an acceleration-deceleration injury, which can include whiplash, shoulder injuries, and traumatic brain injuries.
Deceleration injury can occur in high-speed vehicles when they stop or slow down abruptly or when the occupants of the vehicle are propelled from it while it is moving. Most experiments in deceleration have been done in connection with air travel, in which the acceleration factor is usually much greater than in land vehicles.
Non-acceleration injuries-caused by injury to a restrained head and, therefore, no acceleration or deceleration of the brain occurs within the skull (e.g., blow to the head). These usually result in deformation (fracture) of the skull, causing focal localized damage to the meninges and brain.
Primary injuries are injuries that are caused directly by the impact/penetration, at the time of the accident. Secondary injuries are complications that can arise from primary injuries after the accident and lead to further brain damage.
deceleration injury: [ in´jŭ-re ] harm or hurt; usually applied to damage inflicted on the body by an external force. Called also trauma and wound . brain injury impairment of structure or function of the brain, usually as a result of a trauma. deceleration injury a mechanism of motion injury in which the body is forcibly stopped but the ...
This injury is commonly referred to, or associated with whiplash. Whiplash involves the transfer of acceleration and deceleration forces; usually this is caused by car accidents which cause the body to be thrust forward and then backwards in quick succession.
Objective: To discuss a newtonian physics model for understanding and calculating acceleration-deceleration forces found in sport-related cerebral concussions and to describe potential applications of this formula, including (1) an attempt to measure the forces applied to the brain during acceleration-deceleration injuries, (2) a method of accruing objective data regarding these forces, and (3 ...
Whiplash is a cervical (neck) injury that is caused when the head is thrown either backward by acceleration or forward by deceleration. The acceleration or deceleration in car accidents is typically abrupt, which will cause the head to jerk and be stretched beyond its normal range of motion, straining the muscles and ligaments of the neck.
We present 2 cases of cerebral contusion injury secondary to falling tree limbs hitting the head, illustrating an exception to this observation. In each case, the most prominent lesions were white matter hemorrhagic contusions similar to those associated with acceleration-deceleration types of injuries characterizing falls or motor vehicle ...
