Grading system of neuropathic pain [8]

1. Possible neuropathic pain from the history (If the leading complain is pain)

① History of relevant neurological lesion or disease

② Pain distribution neuroanatomically plausible

2. Probable neuropathic pain from the physical examination

① Pain is associated with sensory signs in the same neuroanatomically plausible distribution

3. Definite neuropathic pain from the confirmatory test

① Diagnostic test confirming a lesion or disease of somatosensory nervous system explaining the pain
