Comparative StudySubacute and chronic low back pain. Reliability and validity of a Swedish version of the Roland and Morris Disability Questionnaire.
The purpose of this study was to investigate test-retest reliability and concurrent validity of a Swedish version of the Roland and Morris Disability Questionnaire (RM-Sw), and to describe demographic factors in patients with low back pain of at least 4 weeks' duration seeking outpatient physical therapy treatment in primary care settings. Seventy-two patients participated in the study. ⋯ Gender, education and occupation were only moderately related to RM-Sw scores, explaining 14% of the variance in the scores. It is concluded that RM-Sw is a reliable and valid measure of functional ability in low back pain.
