Glasgow Coma Scale and Rancho Los Amigos Cognitive Scale

These scales are used to rate a person’s responsiveness when they have experienced a neurologic injury.

The Glasgow Coma Scale is used initially and consists of three sections: eyes, motor, and verbal. The score ranges from a low of 3 to a high of 15. Higher scores indicate that the person is more responsive and more neurologically intact. A person is considered to have a neurologic injury if their Glasgow Coma Score (GCS) is below 8.

The Rancho Los Amigos Cognitive Scale (Rancho) is comprised of 10 levels which range from totally unresponsive to fully independent and appropriate. Individuals who are rated at Levels I to III are considered to be in a minimally conscious state and unable to respond consistently to their environment. Individuals who are rated from Levels IV to VI are more responsive, able to follow commands, and beginning to respond appropriately to their environment. Individuals who are rated from Levels VII to X are mostly appropriate and able to perform basic activities though they may have some long-term cognitive deficits.
