In the Glasgow Coma Scale, which motor response score corresponds to obeying commands?

• A. 5
• B. 4
• C. 6
• D. 3

Answer: (C)

The motor response part of the Glasgow Coma Scale measures how well a patient can move in a purposeful way in response to commands or stimuli. Obeying commands shows that the patient can understand what is being asked and carry out a simple, voluntary task, which demonstrates intact cognitive processing and motor pathways. This represents the top, best possible motor response on the scale. Other motor responses—such as localizing a painful stimulus, withdrawing from pain, abnormal flexion, abnormal extension, or no movement—reflect progressively poorer motor function and consciousness. So, obeying commands corresponds to the highest motor score.
