Which statement reflects a sensory misperception commonly described in CRPS?

• A. Normal sensory perception
• B. Decreased pain response to stimuli
• C. Rapid healing after injury
• D. Misinterpretation of all stimuli as painful

Answer: (D)

In CRPS, the nervous system becomes unusually sensitive to sensory input, so what would normally be harmless feels painful. This exaggerated response to light touch or non-noxious stimuli is called allodynia, a form of sensory misperception where many experiences are interpreted as painful. That’s why the statement describing misinterpretation of all stimuli as painful best captures the common symptom pattern in CRPS. Normal sensory perception isn’t altered in this way, a decreased pain response would actually contradict the heightened sensitivity seen in CRPS, and rapid healing has no relation to how sensory information is interpreted.
