The patients’ functional disability level was determined with the Oswestry Disability Index (ODI), a 10-item questionnaire in which each item is scored from 0 to 5 . The maximum score on the ODI is 50, and higher scores indicate greater functional disability. However, in the present study the maximum score was 45, since the sex life item was omitted due to cultural issues. Therefore relative values are reported here as the total score/total possible score × 10. The MCIC for the ODI was reported as 6 points in a sample of patients with LBP who received physical therapy .
