Traumatic brain injury

A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain by an external force.

Head injury is a broader category, which may involve other damages to the scalp or skull. TBI can cause physical, cognitive or behavioral symptoms, with the outcomes ranging from complete recovery to disability, or death. This could be caused by falls or crashes.

  The Amsterdam Gait Classification facilitates the assessment of the gait pattern in patients after a traumatic brain injury. It helps to facilitate communication in the interdisciplinary team between those affected, doctors, physiotherapists and orthotists.
