acceleration-deceleration injury: injury resulting from a collision between a body part and another object or body part while both are in motion.
Coup injury-- damage occurring at the point of head trauma impact (e.g., where the head hit the ground in a fall) as the brain slides forward within the skull and impacts the inside of the skull. This can occur even if there is no direct external impact to the head (e.g., sudden deceleration in a motor vehicle accident).
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 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.
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 ...

Quick Summary: Whiplash is a neck injury that occurs during a sudden, unexpected movement of the neck in a back and forth or sideways manner.
Acceleration-Deceleration Injuries to the Brain in Blunt Force Trauma. Morrison, Alan L. M.D.; King, ... The proposed pathogenesis for these observed lesions is a forceful impact resulting in the acceleration of the head and brain of a magnitude comparable with that in a motor vehicle accident or a fall.
Effects of Closed Head Injury. Types of Brain Damage. 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.
Main Difference – Acceleration vs. Deceleration. Acceleration and deceleration are two of the most basic concepts encountered in mechanics. The main difference between acceleration and deceleration is that acceleration refers to a rate of change of velocity while deceleration refers to a value of acceleration which is negative. What is Acceleration
