Summary

This observational cross-sectional study aims to determine pain phenotypes in individuals with chronic low back pain (CLBP). Participants will be classified according to a mechanism-based clinical pain phenotyping algorithm as having nociceptive, neuropathic, nociplastic, or mixed pain. Clinical history, quantitative sensory assessment, pain characteristics and distribution, central sensitization-related symptoms, disability, health-related quality of life, and pain catastrophizing will be assessed. In addition, the intra-rater and inter-rater reliability of the pain phenotyping algorithm will be investigated, and the clinical characteristics of different pain phenotypes will be compared.

Pain classification method

A current clinical algorithm will be used to determine the predominant type of pain in individuals with clip. The classification to diagnose nociceptive, neuropathic and nociplastic pain will based on a recent method developed by Nijs et al. This method consists of seven steps in total. These steps question the following, respectively: duration of pain, pain distribution, presence of nociceptive pain, presence of neuropathic pain, phenomenon of hypersensitivity, presence of hypersensitization and presence of specific comorbidity. Besides, inter-rater and intra-rater reliability of pain classification algorithm will be determined by two independent researchers.
