The purpose of this study was to establish test-retest reliability of centre of pressure (COP) measurements obtained by an AccuGait portable forceplate (ACG), mean COG sway velocity measured by a Basic Balance Master (BBM) and clinical balance tests in children with and without balance difficulties. 49 typically developing children and 23 hearing impaired children, with a higher risk for stability problems, between 6 and 12 years of age participated. Each child performed the modified Clinical Test of Sensory Interaction on Balance (mCTSIB), Unilateral Stance (US) and Tandem Stance on ACG, mCTSIB and US on BBM and clinical balance tests: one-leg standing, balance beam walking and one-leg hopping. All subjects completed 2 test sessions on 2 different days in the same week assessed by the same examiner. Among COP measurements obtained by the ACG, mean sway velocity was the most reliable parameter with all ICCs higher than 0.72. The standard deviation (SD) of sway velocity, sway area, SD of anterior-posterior and SD of medio-lateral COP data showed moderate to excellent reliability with ICCs between 0.55 and 0.96 but some caution must be taken into account in some conditions. BBM is less reliable but clinical balance tests are as reliable as ACG. Hearing impaired children exhibited better relative reliability (ICC) and comparable absolute reliability (SEM) for most balance parameters compared to typically developing children. Reliable information regarding postural stability of typically developing children and hearing impaired children may be obtained utilizing COP measurements generated by an AccuGait system and clinical balance tests.
本研究旨在评估 AccuGait 便携式测力板（ACG）的中心压力（COP）测量、Basic Balance Master（BBM）的平均 COG 摆动速度和临床平衡测试在有和无平衡障碍的儿童中的测试-重测信度。49 名正常发育儿童和 23 名听力障碍儿童（有更高的稳定性问题风险），年龄在 6 至 12 岁之间，参与了本研究。每个儿童均进行改良的临床感觉交互平衡测试（mCTSIB）、单侧站立（US）和 ACG 上的串联站立、BBM 上的 mCTSIB 和 US 以及临床平衡测试：单腿站立、平衡木行走和单腿跳跃。所有受试者在同一周的 2 天内完成 2 次测试，由同一位检查者评估。在 ACG 获得的 COP 测量中，平均摆动速度是最可靠的参数，所有 ICC 均高于 0.72。摆动速度、摆动面积、前后 COP 数据的标准差（SD）和左右 COP 数据的标准差（SD）的可靠性为中等到极好，ICC 介于 0.55 至 0.96 之间，但在某些情况下必须谨慎考虑。BBM 的可靠性较低，但临床平衡测试与 ACG 一样可靠。与正常发育儿童相比，听力障碍儿童在大多数平衡参数上表现出更好的相对可靠性（ICC）和可比的绝对可靠性（SEM）。利用 AccuGait 系统生成的 COP 测量和临床平衡测试，可获得有关正常发育儿童和听力障碍儿童姿势稳定性的可靠信息。
