Below: “below-level pain” was defined as neuropathic pain present more than three dermatomes below the neurological level of injury, At: “at level pain” was defined as pain localized to the same dermatome or within three dermatomes below the neurological level. Below-level pain extending to the at-level area is classified as below-level pain if the patient is unable to distinguish two separate pain types. At + below: when the patient presents both types of pain and is able to distinguish two separate pain types.
