Are there any screening tools to help diagnose neuropathic pain?

Various screening tools are available to help physicians diagnose neuropathic pain. The European Federation of Neurological Societies (EFNS) has recently published updated guidelines that provide an overview of, and recommendations on, the key screening tools. These tools are: the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS)2; Neuropathic Pain Questionnaire (NPQ)3; Douler Neuropathique en 4 questions (DN4)4; PainDETECT5; ID Pain6; and the standardized evaluation of pain (StEP)7. All these screening tools have been validated in various neuropathic pain populations; the LANSS, DN4 and StEP utilize interview questions and physical examination, while the NPQ, PainDETECT and ID Pain use only interview questions. Of relevance to the Hong Kong population, one of the screening tools – the ID Pain – has been translated to and validated. The validity of the 6-item patient-completed questionnaire was assessed in 92 patients with either neuropathic or nociceptive pain. At a score of 3 or more, the questionnaire correctly classified 71% of cases. While screening tools are useful for identifying patients with possible neuropathic pain, particularly by non-specialist physicians, they do have limitations. As noted in the EFNS guidelines, these tools fail to identify 10–20% of patients with physician-diagnosed neuropathic pain; hence, they should be used together with a thorough patient history and physical examination.

As such, neurosurgery encompasses treatment of adult and pediatric patients with disorders of the nervous system: disorders of the brain, meninges, and the skull, and their blood supply, including the extracranial carotid and vertebral arteries; disorders of the pituitary gland, disorders of the spinal cord, meninges, and vertebral column, including those which may require treatment by spinal fusion or instrumentation; and disorders of the cranial and spinal nerves throughout their distribution.
