The motor response component assesses which of the following?

• A. Command following, pain localization, withdrawal, posturing, or no response
• B. Orientation
• C. Eye opening
• D. Verbal response

Answer: (A)

The motor response component measures how a patient moves in response to stimuli, reflecting the integrity of motor pathways and level of arousal. It is assessed by observing whether the patient can follow commands, localize to a painful stimulus, withdraw from pain, show abnormal posturing (flexion or extension) in response to pain, or has no movement at all. This sequence captures different levels of purposeful and reflexive movement and is the core of the motor portion of the scale.

The other listed features—orientation, eye opening, and verbal response—are separate aspects of the overall assessment. Orientation evaluates cognitive awareness of person, place, and time; eye opening gauges arousal and responsiveness to stimuli; verbal response assesses language and speech. The motor component uniquely focuses on movement in response to stimuli, which is why it corresponds to the described range from commanding-following to no response.
