The authors recommend this Korean version of the ODI for use in future clinical studies in Korea.

Cross-sectional surveys of health-related quality of life (HRQOL) in patients with low back pain at ambulatory clinics plus 8 weeks of follow-up. ⋯ The HRQOL of patients with low back pain depended on functional status and psychological factors more than simple physical impairment.
