直腿抬高（SLR）受限（Lasque征）被认为是诊断腰椎间盘突出症的重要检查。在一项对55例单侧坐骨神经痛患者的前瞻性研究中，对该体征进行了评估。两个方面进行了调查：1）观察者之间的变化，和2）之间的相关性的测试结果和手术发现。有相当大的观察者之间的变化，三个观察者之间的测量角度引起疼痛。然而，在2/3至3/4的情况下，变化达到10 °。在引起的疼痛类型的分类上也有一些不一致。52例患者接受了手术; 45例椎间盘突出。49例SLR为“阳性”，其中43例存在椎间盘突出。在20例患者中观察到交叉SLR，其中19例患者在手术时有椎间盘脱出。没有SLR限制剂量并不能排除腰椎间盘突出的存在。
Limitation of straight-leg raising (SLR)(Laseque''s sign) is considered an important test in the diagnosis of herniated lumbar disc disease. In a prospective study of 55 patients suffering from unilateral sciatica this sign was evaluated. Two aspects were investigated: 1) the interobserver variation, and 2) the correlation between the result of the test and the surgical finding. There was considerable interobserver variation among three observers concerning the measured angle at which pain was elicited. However, in 2/3 to 3/4 of the cases the variation amounted to 10.degree. or less. There was also some discordance in the classification of the type of pain that was elicited. Fifty-two patients underwent surgery; 45 had a prolapsed disc. SLR was "positive" in 49 cases, 43 of whom harbored a prolapsed disc. Crossed SLR was noted in 20, 19 of whom had a prolapsed disc at surgery. Absence of SLR limitation doses not preclude the presence of a herniated lumbar disc.
