STUDY DESIGN.: A cross-sectional study of 1,804 consecutive patients. OBJECTIVE.: To investigate the prevalence of pathological pain and its distribution features in patients with chronic lumbar spinal disorders. SUMMARY OF BACKGROUND DATA.: Clinical spinal disorders can involve pathological neuropathic pain (NeP) as well as physiological nociceptive pain (NocP), as they have varied pathology, including spinal cord injury, stenosis, and compression. A study conducted by the Japanese Society for Spine Surgery and Related Research (JSSR) has determined a prevalence of 29.4% for NeP in patients with lumbar spinal disorder. However, the data did not include information on pain location. METHODS.: Patients aged 20–79 years with chronic lower back pain (≥3 months, visual analog scale score ≥30) were recruited from 137 JSSR-related institutions. Patient data included an NeP screening questionnaire score and pain location (lower back, buttock, and legs). The association between the pain pathology and its location was analyzed statistically using the unpaired t-test and chi-square test followed by Fisherʼs test). P?
