摘要

Background Diagnostic support tools for lumbar spinal stenosis such as the Self-administered, Self-reported History Questionnaire have been developed in Japan, but no report has demonstrated the diagnostic accuracy of this questionnaire in Japanese primary care settings. This multicenter, cross-sectional survey was performed to evaluate and improve the diagnostic accuracy of this questionnaire for lumbar spinal stenosis patients in Japanese primary care settings.
