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).
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.
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 ...
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.
Acceleration, Deceleration & Whiplash. By far, the most common injury resulting from motor vehicle accidents is whiplash (80% of car crash injuries). Whiplash is a cervical (neck) injury that is caused when the head is thrown either backward by acceleration or forward by deceleration.
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.

Head injuries are generally classified as “open” or “closed.” An open head injury is one in which damage to the brain is caused by a fracture or penetrating wound. In a penetrating head injury, the dural covering of the brain has been breached by an object, such as a bullet or a piece of fractured skull.
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.
