摘要

研究問題與目的：適當的評估工具可協助臨床物理治療師診斷平衡問題。本研究目的是探討新型動態站立板平衡評估之再測信度及效度。研究方法：對象為35位健康受試者，分別接受傳統多方向伸取測試、新型動態站立板多方向伸取測試及以Biodex平衡測試儀測試穩定限制，並於一週後再進行一次動態站立多方向伸取測試。多方向伸取測試是紀錄測試方向的最大伸取距離，Biodex平衡測試則是計算方向控制代表穩定度。統計方式以組內相關係數(Interclass correlation coefficient; ICC)分析新型動態站立板多方向伸取測試再測信度，以皮爾森相關係數(Pearson' s correlation)計算三項測試結果間的相關性。研究結果：新型動態站立板多方向伸取測試各方向皆具有中等以上之再測信度(ICC= 0.631~ 0.781; p ＜ 0.001)。新型動態站立板與傳統多方向伸取測試間具中等之正相關(r = 0.555~0.659; p ＜ 0.001)。建議：以不穩定站立表面的新型動態站立板進行多方向伸取測試具有良好的再測信度，因此建議臨床治療師可使用此一新型工具進行動態站立姿勢穩定度測試，以作為跌倒危險預測的指標。

Purpose: This study aimed to test the reliability and validity of limits of stability (LOS) of a newly developed dynamic standing board. Method: 35 healthy participants were enrolled and completed three balance tests, Multi-directional Reach Test (MDRT), MDRT on dynamic standing board (DSB_MDRT), and LOS test using Biodex Balance System (BBS). For test-retest reliability, DSB_MDRT was tested two sessions one week apart. The distance of maximal reaches with the outstretched arm to three directions were recorded during two MDRTs, and directional control was derived by BBS. Intraclass correlation coefficient was calculated for assessing test-retest reliability of DSB_MDRT, and Pearson´s correlation coefficient was used to test the correlations among all outcome measures. Results: DSB_MDRT showed moderate test-retest reliability for three test directions, and the scores of DSB_MDRT and MDRT showed positive moderate correlations. The result may suggest dynamic standing board is a reliable tool for measuring the postural stability in clinics.
