What Is It?
The DN4 Questionnaire is a reliable and valid diagnostic tool to help clinicians differentiate between neuropathic and non-neuropathic pain. Taking both subjective symptoms and objective signs into account, a score equal to or greater than 4/10 is considered to be positive for neuropathic pain.
This outcome measure is quick and easy to fill out on the fly. With good specificity (89.9%) and sensitivity (82.9%), you can trust the results to help guide your treatment planning.
