Can pain can be more or less neuropathic? Comparison of symptom assessment tools with ratings of certainty by clinicians.

摘要: Chronic pain is generally regarded as being divided into two mutually exclusive mechanisms: nociceptive and neuropathic. Recently, this dichotomous approach has been questioned a model of chronic ‘more or less neuropathic’ suggested. To test whether such spectrum exists, we examined responses by patients with to validated neuropathic assessment tools compared these ratings certainty about the origin their specialist physicians. We 200 (100 each pain) administered self-complete Leeds Assessment Neuropathic Symptoms Signs (S-LANSS score) Pain Scale (NPS). Clinicians were asked rate presence mechanisms on 100 mm visual analogue scale (VAS) (0 = ‘not at all in origin’ ‘completely origin’). The whole sample was tertiles based ascending diagnostic clinicians using VAS labelled ‘unlikely’, ‘possible’ ‘definite’ pain. There significant differences median S-LANSS NPS composite scores between tertile groups. also many item have shown that higher both are indicative greater clinician present. These data support theoretical construct can be more predominantly may useful clinical concept.
