Webb3 maj 2024 · Figure 1 Study flow. We performed ROC analysis of COMPASS-31 scores for “Definite CAN” vs “Early/No CAN” patients. COMPASS-31 score showed a fair diagnostic accuracy with an AUC of 0.731 (0.561–0.901 for 95% CI). A cut-off score of 28.67 for COMPASS-31 showed moderate sensitivity of 77.8% and specificity of 71.1%. Nerve conduction studies along with needle electromyography measure nerve and muscle function, and may be indicated when there is pain in the limbs, weakness from spinal nerve compression, or concern about some other neurologic injury or disorder. Spinal nerve injury does not cause neck, mid back pain or low back pain, and for this reason, evidence has not shown EMG or NCS to be helpful in diagnosing causes of axial lumbar pain, thoracic pain, or cervical spine pain
