Pain assessment and evaluation of patients who have neuropathic pain

Abstract

Pain assessment and physical examination are the first crucial steps in diagnosis of neuropathic pain disorders because these are still solely diagnosed on clinical grounds. The physical examination should be conducted in such a way that all of the positive sensory phenomena, such as allodynia, hyperalgesia, hyperpathia, summation, and after-sensation are elicited. Other physical examination findings should corroborate the diagnostic impression of neuropathic pain. Specific pain diagnosis should then lead to more specific therapy.
