Correlations between the Oswestry Disability Questionnaire (ODQ), the Pain Disability Index (PDI), PDI subscales PDI factor 1 (PDI 1), PDI factor 2 (PDI 2) and visual analogue scale (VAS) pain intensity on the one hand and spine range of motion measures and static and dynamic functional performance tests on the other, were studied in 52 chronic low back pain patients. Comparable groups of male and female patients were studied. A moderately significant (p < 0.01) inverse correlation was observed between the ODQ and rotation to the left even after correction for age, but not when men and women were studied separately. A significant (r = -0.480, p < 0.001) inverse correlation was observed between the repeated squatting test and pain intensity and in men both pain intensity and disability correlated (r = -0.607, p < 0.001) with this particular test. Only for the women were there moderately significant (p < 0.01) inverse correlations between disability assessments and all the physical performance tests with the exception of the static back muscle test. In the women only the isometric lifting test showed a moderately significant inverse correlation (r = -0.504, p < 0.01) with pain intensity. Such apparent gender differences in the overlap between physical performance tests and self-report disability assessments and pain intensity may be clinically relevant. The results will, however, require confirmation on larger groups of chronic low back pain patients.
在52名慢性下腰痛患者中，研究了Oswestry功能障碍问卷（ODQ）、疼痛功能障碍指数（PDI）、PDI分量表PDI因子1（PDI 1）、PDI因子2（PDI 2）以及视觉模拟量表（VAS）疼痛强度与脊柱活动度测量以及静态和动态功能表现测试之间的相关性。对性别可比的患者组进行了研究。即使校正年龄后，ODQ与向左旋转之间仍观察到中度显著（p < 0.01）的负相关，但对男性和女性分别进行研究时则未观察到这种相关性。重复深蹲测试与疼痛强度之间观察到显著（r = -0.480，p < 0.001）的负相关，在男性中，疼痛强度和功能障碍与该特定测试均相关（r = -0.607，p < 0.001）。仅在女性中，功能障碍评估与除静态背部肌肉测试外的所有身体表现测试之间存在中度显著（p < 0.01）的负相关。仅在女性中，等长举重测试与疼痛强度显示出中度显著的负相关（r = -0.504，p < 0.01）。身体表现测试与自我报告的功能障碍评估及疼痛强度之间这种明显的性别差异可能具有临床相关性。然而，结果需要在更大规模的慢性下腰痛患者组中得到证实。
