In the 4-point scale for sensory perception, what does a score of 1 indicate?

• A. No impairment
• B. Slightly limited (verbal commands)
• C. Completely limited
• D. Very limited (painful stimuli)

Answer: (C)

A four-point sensory perception scale is used to quickly gauge how well a patient perceives and responds to stimuli, with higher numbers meaning better responsiveness. A score of one means there is no response to either verbal commands or painful stimuli—sensory perception is completely limited. In clinical terms, this indicates no detectable reaction to any sensory input, signaling severe impairment or unresponsiveness. The other options describe levels where the patient still responds at least to verbal commands or to painful stimuli, which would yield higher scores, so they don’t fit a score of one.
