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 ...
A traumatic brain injury (TBI) can occur when there is a force on the head that results in penetration of the skull (aka open-head injury), or when there is a force to the head that leaves the skull intact but results in injury to the brain tissue (aka closed-head injury).
Direct or indirect force to the head can cause this type of injury. This may be caused by rotational and/or deceleration in the case of both direct and indirect force. Open Head Injury– penetration of the skull with direct injury to the head. Diffuse Axonal Injury– diffuse cellular injury to the brain from rapid rotational movement. This is ...
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.
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 ...
The most common injury resulting from car accidents is whiplash, accounting for 80 percent of all car crash injuries.Whiplash is considered an acceleration-deceleration injury, which can include whiplash, shoulder injuries, and traumatic brain injuries.
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
Diffuse axonal injury (DAI) is a form of traumatic brain injury. It happens when the brain rapidly shifts inside the skull as an injury is occurring. The long connecting fibers in the brain called ...
Acceleration-deceleration, by definition, implies a particular direction or vector. Changes in the vector of acceleration or deceleration (ie, rotational or twisting forces) further complicate the computation of the sum of forces brought to bear on the brain.
