acceleration-deceleration injury: injury resulting from a collision between a body part and another object or body part while both are in motion.


External mechanical forces that can cause TBI. Blow to head (e.g., fall onto pavement, head impacting windshield in a car accident, assault, baseball striking head) Acceleration-deceleration forces, wherein no direct impact is required (e.g., a restrained passenger coming to a sudden stop when a car strikes a tree or telephone pole)


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. Secondary Injury


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.


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.


Classification. Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology.


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 ...


Over 1.4 million individuals sustain traumatic brain injuries each year in the United States. Between 400,000 and 500,000 of these head injuries are severe enough to require hospitalization annually. The financial cost of the diagnostic and rehabilitative/medical programs for traumatic head injury is estimated to be 3.9 billion dollars per year.


Animated Mild Traumatic Brain Injury [Mild Traumatic Brain Injuries (TBIs)] Traumatic brain injuries, also referred to as TBIs, occur across the United States at an estimated rate of 1 every 16 seconds. ... sharp ridges on the inside of the skull during a sudden acceleration or deceleration event.


Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area. It is common for both focal and diffuse damage to occur as the result of the same event; many traumatic brain injuries have aspects of both focal and diffuse injury.
