| 目的研究青年下背痛患者躯干肌力和腰椎曲度的变化以及二者之间的关系。 方法应用CYBEX-6000型等速测试训练系统测试下背痛组和正常组的躯干肌力指标，并在立位腰椎侧位X光片上测量腰椎曲度，两组间进行比较。 结果躯干屈肌：下背痛组PT/ BW与正常组无差异（P>0.05）, TAE低于正常组（P<0.05），ER大于正常组（P<0.05）。躯干伸肌：下背痛组PT/ BW和TAE均低于正常组（P<0.05）， ER与正常组无差异（P>0.05）。下背痛组的F/E大于正常组（P<0.05）。下背痛组腰椎曲度小于正常组（P<0.05）。 结论青年下背痛患者存在着明显的腰背肌肌力下降和腰椎生理曲度变直，以及由腰背肌肌力下降所致的躯干肌肌力失衡。 |

| Objective To examine the change of trunk muscle strength and lumbar curvature ,and explore the relationship between them in young patients with low back pain. MethodsThe indices of trunk muscle strength(PT/ BW、TAE、ER、F/E) were measured in 40 patients with low back pain and 40 healthy subjects with CYBEX-6000 isokinetic testing system. The lumbar curvature was measured on the X-ray films of these patients. All of the indices were compared between the two groups. ResultsPT/ BW of trunk flexors showed no significant difference between the patients and healthy subjects（P>0.05）, TAE of flexors in patients were lower than those in the healthy subjects（P<0.05）， ER of flexors in patients were greater than those in healthy subjects（P<0.05）. PT/ BW and TAE of extensors in patients were lower than those in the healthy subjects（P<0.05）, ER of extensors showed no significant difference between the two groups （P>0.05）. F/E in patients were greater than those in healthy subjects（P<0.05）. Lumbar curvature in patients were lower than those in the healthy subjects（P<0.05）. ConclusionIn young patients with low back pain, strength of the trunk extensors was significantly declined, as a result, strength of the trunk muscles lost its balance and the lumbar curvature was usually decreased. |
