Difference in evaluation of patients with low back pain using the Japanese Orthopaedic Association Score for Back Pain and the Japanese Version of the Roland-Morris Disability Questionnaire

The clinical signs in patients with low back pain and/or lumbar diseases are not associated closely with the Japanese version of the Roland-Morris Disability Questionnaire. Therefore, a combination of the Japanese version of the Roland-Morris Disability Questionnaire and the Japanese Orthopaedic Association score can provide wide-ranging assessment of the level of impairment in patients with low back pain and/or lumbar diseases.
