平衡测试仪的信度研究

Reliability of balance performance monitor in the assessment of balance function

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 study the reliability and sensitivity of balance performance monitor (BPM) in the a ssessment of balance function. Methods Twenty healthy subjects (control group) and 20 patients with neurological disorders participated in the study. They were assessed twice with BPM within one week. All the subjects performed the BPM twice, respectively, with eye opened and eye closed at each assessment session. Results There were moderate to high correlations in all the parameters of BPM between the two assessments (ICC=0.85 0.98). The parameters obtained from the patients were significantly different from those from the controls( P < 0.01 ). Conclusion The BPM has high reliability and sensitivity when it is used to assess the balance function of healthy subjects and patients with neurological disorders.
