Objective <p>To determine whether specific neuroreflex points exist on the auricles of subjects suffering from idiopathic chronic low back pain (icLBP).</p> Methods <p>Using the pressure pain test (PPT), we tested both auricles of 100 patients with icLBP [as low back pain (LBP) group] and those of 100 healthy subjects [as healthy control (HC) group].</p> Results <p>The average number of painful points, in the 17, 18, and 19 sectors of ROMOLI M’s sectogram, and in the Lumbosacral Vertebrae (AH₉), Hip (AH₅), and Heart of Posterior Surface (P₁) areas according to the Chinese standardized paper, was significantly higher in the LBP group compared to the HC group (<i>P</i>&lt;0.05). In particular, in the LBP group, painful points could be clearly clustered into two main areas based on anatomy, which we called L₁ and L₂. In all other areas and sectors of the auricle, the average number of painful points did not differ significantly between the two groups. In the LBP group, 94.7% of patients had at least one painful point in the two areas.</p> Conclusion <p>L₁ and L₂ are two specific points on the auricle that can reflect icLBP.</p>
