Relationship of the Pain Disability Index (PDI) and the Oswestry Disability Questionnaire (ODQ) with three dynamic physical tests in a group of patients with chronic low-back and leg pain.
OBJECTIVE To determine the relationship between overall disability in daily activities , assessed with the Pain Disability Index ( PDI ) and the Oswestry Disability Question naire ( ODQ ) , and impaired performance on three physical tests in patients with chronic low-back pain . DESIGN AND SUBJECTS The PDI and ODQ were administered in a cross-sectional study , before beginning a back rehabilitation program , to 45 patients with low-back pain of > or = 3 months ' duration , with or without radiation to the legs . All patients also performed repetitive sit-up , arch-up , and squatting tests . SETTING Tertiary care center . RESULTS Modestly significant ( p < 0.05 ) or significant ( p < 0.01 ) inverse correlations ( Pearson 's r = 0.30 - 0.41 ) were noted between the PDI and the ODQ and all three physical performance tests . When normative data were used , the correlation ( Spearman 's rs = -0.45 ) between PDI and the squatting test remained significant ( p < 0.01 ) , whereas it was modestly significant ( rs = -0.33 , p < 0.05 ) between the ODQ and squatting test and between the PDI and arch-up test ( rs = -0.35 , p < 0.05 ) . Compared with patients presently working , those on sick leave had significantly higher scores on the PDI and ODQ ( Wilcoxon 's two- sample test : p < 0.001 ) and also significantly worse performance on all physical tests ( p < 0.001 ) . CONCLUSIONS The PDI and ODQ , as measures of self-perceived disability , and impaired performance on repetitive squatting , arch-up , and sit-up tests , as measures of physical capability , show some overlap in low-back-pain patients . Both types of disability measures are clearly influenced by the patient 's work status
