摘　　要：目的:研究便携式人体平衡测试仪评定人体站姿平衡功能的信度及敏感性,以指导其临床应用。方法:20例脑外伤及脑卒中患者作为病例组,20例健康人作为正常组,由同一名测试者使用便携式平衡测试仪在2周内对2组受试者的站姿平衡功能进行2次测试,每次测试分别在睁眼和闭眼状态下各1次。结果:2组内相关系数进行信度分析,结果显示2次测试间有较好的重测信度(ICC=0.84～0.92);病例组与正常组各测试指标间差异有统计学意义(P<0.01)。结论:便携式平衡测试仪具有很好的重测信度和敏感性,是定量评定人体站姿平衡功能的理想工具,并且还可用于评定人体坐姿平衡功能,其信度和敏感性有待进一步研究。Objective： To investigate the validity and sensitivity of portable body balance testing system in assessing body standing balance function. Methods： Twenty patients with stroke and traumatic brain injury served as case group, and 20 healthy people as control group. They were assessed twice with portable body balance testing system within two weeks, and standing balance functions were assessed under the conditions of the eyes opened and closed at each assessment session. All the tests were done by the same tester. SPSS version 13.0 was used to analyze the data. Intraciass correlation coefficients （ICCs） were used to assess the validity. Results： The results demonstrated a high inter-rater validity between two assessments （ICC= 0. 84--0. 92）. The parameter values between two groups showed significant difference （P〈0, 01）. Conclusion： The portable body balance testing system has high validity and sensitivity, and is a useful tool for quantitative assessment of body standing balance function. The portable body balance testing system can be also used to assess the sitting balance function.
