影响直腿抬高试验的多因素分析

Multiple Regression for Straight Leg Raising Test.

历史回顾。考证直腿抬高试验的出处及检查方法，纠正直腿抬高试验与Ｌａｓｅｇｕｅ征混为一谈的错误观点。对影响直腿抬高试验的多因素进行分析。方法：１９９０～１９９７年５０５例椎间盘突出病例的直腿抬高试验的影响因素进行回归分析。结果：直腿抬高试验与急慢性病程、椎间盘突出率、侧隐窝狭窄、椎间盘突出位置（中央型、侧旁型）、间歇性跛行距离等相关。而与年龄、性别、族别（汉族与维、哈、回族比较）、椎间盘突出大小、单或多间隙突出、侧旁突出的根前、根腋、根肩型不相关。比较Ｌ４．５、Ｌ５Ｓ１椎间盘突出的直腿抬高试验度数。二者存在显著性差异，Ｐ＜０．０１。结论：影响直腿抬高试验相关因素为：急慢性病程、椎间盘突出率、侧隐窝狭窄程度、椎间盘突出位置及间歇性跛行距离。

Objective:History,provenance and method of straight leg raising(SLR)test were inspected,The wrong point regarding SLR as Lasegues sign was corrected,analyzed the main factors affecting SLR.Methods:From 1990 to 1997,SLR in 505 patients with lumbar disc herniation(LDH)were analyzed by multiple regression.Results:The degree of SLR was correlated to acute and chronic course,disc herniation rate,lateral recessus stenosis,location of prolapsed disc(central or lateral)and walking distance of intermittent claudication,not correlated to age,sex,nation(Han versus Uygarl、Hazak、Hui),size of disc herniation,one or multiple levels disc herniation and different types of lateral disc herniation to nerve root.There was significant difference in SLR between patient with disc herniation in L 45 and L 5S 1.(P<0 01).Conclusion:The main factors of affecting SLR were acute and chronic course,disc herniation rate,lateral recessus stenosis and walking distance of intermittent claudication.
