Tests of limb and back motor performance were administered to males with low back pain at the completion of a back-school program.
The objective of the study was to determine the relationship between such motor performance and the propensity for abnormal illness behavior as indicated by the Waddell score.
Previous studies in similar subjects had revealed a nonbiologic pattern of lumbar strength and movement in back-school patients, and correlations between lumbar variables, Waddell score, and 'global' psychologic measures. This suggested that psychologic factors might affect motor performance in body segments unrelated to the low back in such patients.
Mean performance of the group with a high Waddell score (indicating a propensity for abnormal illness behavior) was lower on all tests, including those that did not involve the low back, in comparison to the group with a low Waddell score (P < .01, sign test).
For all members of this population of patients, motor performance on dynamometry of any body segment does not necessarily reflect the maximum physical capacity.
在一个背部训练项目结束时，对患有下背痛的男性进行了肢体和背部运动表现测试。
本研究的目的是确定这种运动表现与由瓦德尔评分所表明的异常疾病行为倾向之间的关系。
之前对类似受试者的研究揭示了背部训练患者腰椎力量和运动的非生物学模式，以及腰椎变量、瓦德尔评分和“整体”心理测量之间的相关性。这表明心理因素可能会影响此类患者与下背无关的身体部位的运动表现。
与瓦德尔评分低的组相比，瓦德尔评分高（表明有异常疾病行为倾向）的组在所有测试中的平均表现都较低，包括那些不涉及下背的测试（P <.01，符号检验）。
对于这群患者中的所有成员，任何身体部位的测力计运动表现不一定反映最大身体能力。
