The supine straight-leg raise (SLR) test has the potential to be exploited by malingering patients. The sitting SLR is believed to be less recognizable, therefore decreasing the chance of fabrication. The authors aim to compare the supine and sitting SLR test in patients with radiculopathy.
A total of 107 patients with radiculopathy were included in this study. Two groups were created: patients with workman's compensation (Group 1) and a control group of patients without litigation claims (Group 2).
Mean age was 47.3 ± 1.3 years with a 51% female population. Correlation analysis demonstrated association between mean angles in both positions, = 0.248 with significance = .01. There was equivalence in the mean angles in sitting position of 37 ± 3° compared to 35 ± 2° in supine position ( = .549). There was no significant difference in the mean angle at which the test became positive in the litigation group in the sitting or supine position compared to the nonlitigation group, = .616 and = .49 respectively.
This study demonstrated that the SLR test is equivalent in the sitting and supine position. Therefore, patients with a positive test should have similar angles in both positions, decreasing the chance of falsifying the examination.

仰卧位直腿抬高（SLR）试验有可能被诈病患者利用。坐位直腿抬高试验被认为较难被识别，因此降低了伪装的可能性。作者旨在比较神经根病患者的仰卧位和坐位SLR试验。
本研究共纳入107例神经根病患者。分为两组：工伤赔偿患者（第1组）和无诉讼索赔的对照组患者（第2组）。
平均年龄为47.3±1.3岁，女性占51%。相关性分析显示两个体位的平均角度之间存在关联，r = 0.248，P = 0.01。坐位平均角度为37±3°，仰卧位为35±2°，二者相当（P = 0.549）。与非诉讼组相比，诉讼组坐位和仰卧位试验阳性时的平均角度无显著差异，分别为P = 0.616和P = 0.49。
本研究表明SLR试验在坐位和仰卧位时等效。因此，试验阳性的患者在两个体位应具有相似的角度，从而降低检查结果造假的可能性。
