进行了一项前瞻性、盲法队列研究，以调查腰椎动力测量中测量的生物力学变量与几项心理测试和非器质性疼痛行为测量之间的关系。85名患有腰痛超过5周的18-60岁男性参与了这项研究。用Waddell评分测量非器质性疼痛行为，用Isostation B-200腰椎测力仪测量腰椎功能。研究人员还进行了两项简短的心理测试，即库珀史密斯自尊量表和类似的健康自我评定。采用t检验、Pearson r相关、方差分析和多元逐步逻辑回归计算生物力学变量与心理测试的关系。表现出过度疾病行为的患者（Waddell评分3-5）在几乎所有生物力学变量上的表现均显著差（P < 0.01）。库珀史密斯自尊得分和“感觉”得分与运动表现的相关性略弱，但仍然显著。结果表明，该人群在生物力学测试中的不良表现可能是一种异常疾病行为，因此可能无法准确反映神经肌肉骨骼功能的有机改变。
A prospective, blinded cohort study was performed to investigate the relationship between biomechanical variables measured during lumbar dynamometry and several psychological tests and measures of nonorganic pain behavior. Eighty-five men, aged 18-60 years, who had had low-back pain for longer than 5 weeks participated in the study. Nonorganic pain behavior was measured with the Waddell score, and lumbar function was measured with the Isostation B-200 Lumbar Dynamometer. Two brief psychological tests, the Coopersmith Self-Esteem Inventory and an analog self-rating of wellness, were also administered. Relationships between biomechanical variables and psychological tests were calculated with the t-test, the Pearson r correlation, analysis of variance, and multiple step-wise logistic regression. Patients who exhibited excessive illness behavior (Waddell Scores 3-5) performed significantly worse (P < .01) on almost all biomechanical variables. The Coopersmith Self-Esteem Score and "feelings" score had a slightly weaker but still significant correlation with motor performance. The results suggest that poor performance on biomechanical testing in this population may be a form of abnormal illness behavior and thus may not accurately reflect organic alterations of neuromusculoskeletal function.
