正常人腰椎动态功能评定

Evaluation of dynamic function of lumbar spine in healthy people

目的:对正常人的腰椎动态功能进行评定,以期为今后建立本土化数据库提供有益的资料。方法:120例在过去半年内无下腰痛病史或没有背部手术的志愿者参与此研究,并使用标准的程序对受试者的腰椎动态功能进行评定,然后对数据进行分析。结果:与白色人群所得出的正常值相比,在很多指标有很大的差异,正常人男、女性在各个活动方向的等长最大力矩等方面均存在显著差异。结论:以白种人群为基础所得出的正常数据应不适用于正常人,应有更多针对性的研究,并据此建立适用与本土化的正常值。

AIM:To evaluate the dynamic function of lumbar spine in healthy people so as to provide helpful data for the future establishment of native database. METHODS:A total of 120 subjects without history of low back pain in the past six months or any prior back surgery volunteered to participate in this study.The dynamic function of lumbar spine of each subject was assessed with the lsostation B 200 according to the protocol provided by the manufacturer,and then the data were analyzed. RESULTS:There were great differences in many indexes between the Caucasian population and the subjects in the present study.Compared with Caucasian population,Chinese subjects showed a significant difference in isometric maximum torque in all directions between male and female. CONCLUSION:The normative database based on the Caucasian population should not be applicable for Chinese population.There should be more normative data for the study of the Chinese,according to which some useful information for Chinese population should be established.
