摘要
目的:探讨5次坐立试验(FTSST)在预测老年人跌倒危险方面的有效性。方法:137位老年人受试者参与本研究并分为跌倒组和非跌倒组。对受试者进行FTSTS和利用功能性蹲屈测试训练仪来测量下肢肌力。结果:41位受试者在过去一年内发生过跌倒。跌倒组和非跌倒组的受试者在年龄、FTSST时间和下肢肌力之间的比较有显著差异(P<0.001)。Spearman相关分析结果显示FTSST时间与肌力、年龄和跌倒史之间显著相关(P<0.001)。Logistic回归分析因变量和跌倒史关系,FTSST时间是预测跌倒危险最主要的变量(OR:1.406)。ROC曲线分析显示FTSST最佳临界值为9.75s,其敏感性为78%,特异性为70.8%,ROC曲线下面积为0.81。结论:FTSST作为一个简便、快捷的功能性测试工具可以有效预测老年人跌倒危险,FTSST鉴别力优于下肢肌力。
Objective： To investigate the usefulness of the five times sit to stand test（FTSST） as an assessment tool for pre- dicting falls. Method： One hundred and thirty-seven elderly volunteers were recruited and divided into two groups： fall group and no-fall group. All subjects were tested by FI＇SST and functional squat system for quantifying their muscle strength. The data were analyzed by using the statistic description, Spearman＇s correlation coefficient, Logistic re- gression analysis and receiver operating characteristic （ROC） curve analysis. Result： Forty-one volunteers reported fall during the past year. The fall group showed higher FTSST time, higher age and lower muscle strength than those in no-fall group （P〈 0.001）. There were significantly correlation of the lower-hmb strength and history of falls with FTSST time（s） （P〈0.001）. The Logistic regression analysis revealed that only FTSST was significantly related to falling （odds ratio： 1.406）. Receiver operating characteristic analysis determined a cut off of 9.75s（sensitivity, 78%; specificity, 70.8%） for discriminating between fallers and no-fallers, with an area under the curve of 0.81. Conclusion： The FTSST might be a quick, easily functional testing tool that was useful for predicting falls in el- derly people, and FTSST was better than lower-limb strength test at discriminating between fallers and no-fallers.
