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.

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.
