acceleration-deceleration injury: injury resulting from a collision between a body part and another object or body part while both are in motion.
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.
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.
Deceleration injury, impact injury to a body within or upon a rapidly moving object caused by the forces exerted when the object is brought to a sudden halt. Deceleration injury can occur in high-speed vehicles when they stop or slow down abruptly or when the occupants of the vehicle are propelled ...
Brain Regions Commonly Affected in TBI. 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).
Coup injury may be caused when, during an impact, the brain undergoes linear acceleration and deceleration forces or rotational forces, causing it to collide with the opposite side of the skull. The injuries can also be caused solely by acceleration or deceleration in the absence of an impact.
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.
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.
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.
