不同量表对慢性阻塞性肺疾病患者跌倒的应用价值

Application of Berg Balance Scale,Mini-Balance Evaluation Systems Test and Brief-Balance Evaluation Systems Test for Falls in Chronic Obstructive Pulmonary Disease Patients

目的比较Berg平衡量表(BBS)、平衡评价系统测试(BESTest)的两个简化版本Mini-BESTest和Brief-BESTest对慢性阻塞性肺疾病(COPD)患者跌倒风险的区分效果。方法 2016年9月至2017年3月,对22例有跌倒史的COPD患者和年龄与之匹配无跌倒史的66例COPD患者,采用BBS、Mini-BESTest和Brief-BESTest进行评定,进行配对Logistic回归、对数似然估计,计算数据分布的偏态系数。结果 BBS、Mini-BESTest和Brief-BESTest评分均有区分价值(OR<0.252,P<0.01);Brief-BESTest最大似然数最低(5.372),其次为Mini-BESTest(12.918)和BBS(17.644);Brief-BESTest和Mini-BESTest无天花板效应,BBS有天花板效应。结论 BBS、Mini-BESTest和Brief-BESTest均能预测COPD患者跌倒风险,Brief-BESTest预测能力最高;BBS在COPD患者中有天花板效应,Brief-BESTest和Mini-BESTest无天花板效应。

Objective To compare the differentiating effect of Berg Balance Scale(BBS),Mini-Balance Evaluation Systems Test(Mini-BESTest)and Brief-BESTest on the risk of falls in chronic obstructive pulmonary disease(COPD)patients.Methods From September,2016 to March,2017,22 COPD patients with history of falls and other age-matched 66 COPD patients without history of falls were assessed with BBS,Mini-BESTest and Brief-BESTest.The data were compared with paired Logistic regression,Log-likelihood estimate,and the skewness coefficient were calculated.Results BBS,Mini-BESTest and Brief-BESTest all were valuable for differentiating the risk of falls in COPD patients.Log-likelihood estimate value was the least in Brif-BESTest(5.372),followed with Mini-BESTest(12.918)and BBS(17.644).There was not a ceiling effect in Brief-BESTest and Mini-BESTest,but there was in BBS.Conclusion All the BBS,Mini-BESTest and Brief-BESTest can predict the risk of falls in patients with COPD,and Brief-BESTest is the most predictive.There is a ceiling effect in BBS for COPD patients,but not in Brief-BESTest and Mini-BESTest.
