acceleration-deceleration injury: injury resulting from a collision between a body part and another object or body part while both are in motion.
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.
Whiplash is considered an acceleration-deceleration injury, which can include whiplash, shoulder injuries, and traumatic brain injuries. Rapid acceleration and deceleration in car accidents can be caused a variety of different ways, but most commonly occurs when an abrupt change in speed occurs.
Mechanisms of Injury. What is the physiological impact of a traumatic brain injury? ... Typically associated with acceleration-deceleration injuries, there may be shearing or twisting of axonal fibers (white matter tracts) in the brain. This occurs most often in the frontal and temporal lobes.
Barth et al 15 suggested that this newtonian physics approach be applied to the measurement of sport-related acceleration-deceleration head injury to add to our understanding of injury severity. Deceleration, which must necessarily follow acceleration, is the key issue when discussing the forces applied in mild concussion.
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.
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.
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 ...
Deceleration Training to Avoid Injuries and Improve Performance Part 2. By: Lee Taft. In part one of Deceleration Training, I wrote about the importance being able to decelerate as a tactic to expose opponents “biting on a fake or move”.Deceleration Part 2 , I will explained how to train for deceleration of multi-directional speed.
Closed head injury can cause several different types of brain injury, including coup contre-coup, acceleration-deceleration trauma, rotational trauma and molecular commotion. According to Love and Webb (1992) the most predominant injury type is acceleration-deceleration trauma.
