People suffering from low back pain (LBP) fail in performing many daily living activities. The aim of this study was to compare two different back pain scales and to determine the relation between pain intensity and these scales on women with low back pain. Fifty-five women with chronic LBP (X ± SD: 37.76 ± 5.12 years) participated in this study. Their disabilities were determined by Quebec Back Pain Disability Scale (QBPDS) and Oswestry Low Back Disability Questionnaire Scale (OLBDQS). Pain intensity was measured by a visual analogue scale (VAS). Outcome of this study showed that the QBPDS and OLBDQS were highly correlated. Also, VAS scores were correlated with both scale scores but this correlation was less strong. These two disability measuring methods are comparable, but OLBDQS has the advantage of requiring shorter time. © 2005 VSP.
