Our purpose was to test the hypothesis that feigned exertions would show greater variability in both force and electromyograms than would sincere exertions over repeated testing sessions. Eleven normal subjects made sincere and feigned exertions while performing the five-handle position Jamar grip test. The subjects were tested 6 times in a 3- to 5-week period. Contrary to the hypothesis, feigned exertions did not show greater variability than sincere exertions. Both sincere and feigned exertions were highly consistent over the six sessions. However, the sincere and feigned exertions did differ in the patterns of force and electromyogram on the five-handle position test. These results and those of previous studies suggest that clinicians should use more than one type of test when testing suspected malingerers.
我们的目的是检验这样一个假设，即在多次重复测试过程中，伪装用力相比真诚用力在力量和肌电图方面会表现出更大的变异性。11名正常受试者在进行五手柄位置的贾马尔握力测试时进行了真诚和伪装的用力。受试者在3至5周的时间内接受了6次测试。与假设相反，伪装用力并未表现出比真诚用力更大的变异性。真诚用力和伪装用力在六次测试过程中都高度一致。然而，在五手柄位置测试中，真诚用力和伪装用力在力量和肌电图模式上确实存在差异。这些结果以及先前研究的结果表明，临床医生在测试疑似诈病者时应使用不止一种类型的测试。
