目的 探讨平衡测试仪的信度和敏感性 ,为临床应用提供客观依据。方法 2 0例正常人和 2 0例神经疾患患者 ,1周内采用平衡测试仪对每位测试对象进行 2次测试 ,每次测试时 ,分别在睁眼和闭眼状态下重复测试两次。结果 两次测试结果各指标高度相关 (ICC =0 .85～ 0 .98) ,病例组与对照组各个测试指标差异有显著性 (P <0 .0 1)。结论 平衡测试仪用于评定正常人和神经疾患患者的平衡功能具有较高的信度和敏感性。
Objective To explore the reliability and sensitivity of the balance tester and provide an objective basis for clinical application. Methods Twenty patients with normal and 20 patients with neurological disorders underwent two tests on each test subject with a balance tester within one week. During each test, the test was repeated twice with blink and closed eyes. Results The results of the two tests were highly correlated (ICC = 0.85 to 0.98), and there was a significant difference between the test group and the control group (P < 0.01). Conclusions Balance testers are used to assess the balance of function in normal and neurological patients with high reliability and sensitivity.
