Summary[edit | edit source]
It is a clinician-administered questionnaire consisting of 10 items. Seven items related to pain quality (i.e. sensory and pain descriptors) are based on an interview with the patient, and 3 items based on the clinical examination [1].The DN4 (which stands for Douleur Neuropathique 4) is one of the questionnaires that can be usefu in diagnosing neuropathic pain. It has components of how the pain feels to the patient but also requires the examining health professional to assess whether there is reduced sensation (hypoaesthesia) to touch or pinprick, and whether light brushing increases or causes pain (allodynia)[2].Questionnaire initially written in French but immediately translated into English by the same team. The scale has been widely used since 2005 because of its simplicity. It evaluates neuropathic pain following central and peripheral neurological lesions.It is also used for diagnostic purposes, allowing the clinician to determine if the pain is of neuropathic origin.[3]
This questionnaire has been well validated in a number of studies.
The DN4 questionnaire was originally developed and validated in French.[4]

The Persian version of DN4 questionnaire is a reliable, valid, feasible, and easily administered tool for precise discrimination neuropathic pain from NNP in Farsi. The characteristics of this test can assist practitioner to diagnose neuropathic pain accurately for both clinical and research purposes.[6]
The DN4 is an easy-to-use screening tool that is reliable for discriminating between neuropathic and nociceptive pain conditions in daily practice. [7]
