What is the Ranchos Los Amigos Scale?

Like the Glasgow Coma Scale, the Ranchos Los Amigos Scale is a system used by medical professionals to evaluate victims of traumatic brain injuries, and is based on cognitive and behavioral presentations as victims emerge from a coma.  The scale runs from 1 to 8, with 1 being a person who is non-responsive and has no responsive cognitive functioning, while a score of 8 indicates appropriate and purposeful functioning.  Victims of traumatic brain injury will progress up the scale as they recover.  Recovery for victims is different from person to person, and some victims may plateau at a certain level on the scale.
