Answer

Bedside testing for allodynia and hyperalgesia is important to remove subjectivity from the sensory portion of the examination when confirming the diagnosis of CRPS. Detailed sensory testing can document impairment of warm and cold sensations; heat pain; static, dynamic, and pinprick allodynia; heat and mechanical hyperalgesia; and temporal summation. [65, 66]
