How is the Glasgow Coma Scale (GCS) motor response scored?

The Glasgow Coma Scale (GCS) motor response is scored based on a patient's ability to follow commands, localize stimuli, withdraw from painful stimuli, exhibit flexion in response to pain, show extension in response to pain, or display no response at all.

This scoring system provides a detailed evaluation of a patient's neurological status, particularly in assessing their level of consciousness and the integrity of their neurological function. The categories of movement indicate varying degrees of responsiveness and neurological function. For example, a person who can localize to a painful stimulus demonstrates more preserved motor function than someone who merely withdraws from pain, which is why the specific distinctions in scores (commands, localizing, and various forms of response to pain) are critical for accurately assessing a patient’s condition in trauma or critical care situations.

Overall, the GCS motor response scoring gives essential insight into a patient's brain function, aiding healthcare providers in determining the severity of their condition and guiding treatment decisions.
