摘要： 目的研究闭链动作下老年人下肢神经肌肉功能的年龄相关性。方法45例符合入选条件的老年人分成60～69岁组、70～74岁组和75岁组，每组15例。应用功能性蹲屈测试系统(FSS)分别测试受试者下肢的等长肌力、反应时间和协调性。采集记录最大等长伸展肌力标准值、平均等长伸展肌力标准值、总体平均反应时间、平均偏移距离。结果经Pearson相关分析，年龄与各项指标均有显著相关性(P<0.05～0.01)；经组间方差分析，协调性在各组人群中均无显著性差异；最大肌力标准值和平均肌力标准值在60～69组均优于其他两组(P<0.05)；60～69岁组的总体平均反应时间优于75岁组(P<0.05)；70～74岁组与75岁组各项指标均无显著性差异(P>0.05)。结论老年人的下肢神经肌肉功能具有年龄相关性。

Abstract: Objective To explore the relationship between the somatosensory evoked potential (SEP) diversification during operation and the short term outcome of ossification of posterior longitudinal ligament (OPLL) of cervical spine. Methods 70 OPLL inpatients from February 2008 to February 2011were included in this study. All patients received anterior cervical operation. According to the diversification of the SEP during surgery, the patients were divided into 2 groups. The preoperative and postoperative JOA scores of the OPLL patients were collected. Results There were 35 patients in the SEP no change group and 30 in SEP improved group. There was no difference in the preoperative JOA scores between them (P>0.05), but was significantly different in the postoperative JOA scores (P>0.05). Conclusion There is some relationship between the SEP diversification during operation and the short term outcome of OPLL of cervical spine.
