Inter- and intra-rater-reliability of a clinical framework for spine-related neck-arm pain.

Objective: A mechanism-based clinical framework for spine-related pain differentiates (i) somatic referred pain, ii) heightened nerve mechanosensitivity, iii) radicular pain, iv) radiculopathy and mixed-pain. This study aimed to determine the reliability of proposed framework.

Method: Fifty-one people with unilateral spine-related neck-arm pain were assessed and categorized by examiner-1.
