老年人膝关节和踝关节位置觉的重测信度

背景：目前国内外关节位置觉的研究主要以青年人为对象,而老年人在不同角度关节位置重现的重测信度研究比较缺乏。目的：观察老年人膝关节和踝关节在不同角度关节复位测试的重测信度。方法：在Biodex system 3等速系统上用被动复位测试法测试28名健康老年人的膝、踝关节本体感觉,以被动复位绝对误差角度作为个体位置觉能力优劣的代表。重测信度评价指标为组内相关系数（ICC）。结果与结论：左右两侧膝关节位置觉测试在不同角度都具有良好的重测信度,ICC值为0.851～0.973;左右两侧踝关节位置觉测试在跖屈与背伸位具有中等以上的重测信度,ICC值为0.742～0.964;左侧踝关节复位的绝对误差角度小于右侧踝关节（P〈0.05）,且左侧（ICC为0.870～0.964）踝关节重测的相关系数高于右侧（ICC为0.742～0.944）。提示老年人膝关节和踝关节位置觉重测的相关性良好,并且左侧踝关节的相关性高于右侧。

Test-retest reliability of joint position in the knee and ankle of older people

BACKGROUND：At home and abroad there are many studies of joint position in young people,but in older people,studies about test-retest reliability of joint position are lack.OBJECTIVE：To determine the test-retest reliability of joint position in the different position of knee and ankle in older people.METHODS：Ankle and knee joint position of 28 healthy older people was measured with passive replication test on the Biodex system 3 dynamometer.The absolute error angle of passive replication test was used to assess ankle position sense.The indicator of test-retest reliability of joint position was intraclass correlation coefficient（ICC）.RESULTS AND CONCLUSION：The test-retest reliability of joint position was modest in the different positions of both knee,and the values of ICC were from 0.851 to 0.973.The test-retest reliability of joint position was also modest in plantarflexion and dorsiflexion of both ankle,and the values of ICC were from 0.742 to 0.964.The absolute error angle of passive replication test in the left ankle was better than the right（P 0.05）;the test-retest reliability of the left ankle（ICC was from 0.870 to 0.964） was better than that of the right ankle（ICC was from 0.742 to 0.944）.The test-retest reliability of joint position is good in the knee and ankle of older people,and the correlation of the left ankle is better than the right.Wang XQ,Zheng JJ,Yu ZW,Liu J,Feng Y,Zeng DM,Chen QH.Test-retest reliability of joint position in the knee and ankle of older people.Zhongguo Zuzhi Gongcheng Yanjiu yu Linchuang Kangfu.2011;15（35）：6639-6642.http：//www.crter.cn http：//en.zglckf.com]
