the Rancho Los Amigos Levels of Cognitive Functioning Scale (LOCF) or Rancho Scale, is a medical scale used to assess individuals after a closed head injury, including traumatic brain injury, based on cognitive and behavioural presentations as they emerge from coma.
After being assessed based on the LOCF, individuals with brain injury receive a score from one to eight.
[2] Each of the eight levels represents the typical sequential progression of recovery from brain damage.
[2] This eight-level scale was found to possess test-retest and interrater reliability as well as concurrent and predictive validity.
[3] It is widely used clinically and is often paired with the Glasgow Coma Scale in health care facilities.
