摘要

背景與目的：平衡功能測試為評估日常生活功能重要的一環，但多樣化之測試項目中，彼此間的相關性與影響是值得探討的課題。本研究之目的為探討常見平衡功能測試項目之間的相關性。方法：大台北地區39位第一次中風患者參加受試，分別使用平衡測試儀(Balance Master)、電子位移計、柏格氏平衡量表(Berg Balance Scale)和步速來量化病人平衡能力。平衡測試儀量化(1)靜態平衡中，量測站立不對稱性與姿體晃動度，(2)動態平衡中，量測方向控制與最大位移量和(3)坐到站之動作時間。電子位移計則量化病人功能性前伸之距離，柏格氏平衡量表與步速為測量功能性平衡活動之表現。統計方式以皮爾森相關係數r(Pearson product-moment r)來檢驗彼此間的相關性。結果：柏格氏平衡量表除了站立不對稱性無相關外，與其他各測試項目幾乎都有顯著相關（r介於0.30與0.70），但功能性前伸距離只和步速、柏格氏平衡量表有相關(r=0.35，r=0.32)。動態平衡兩項測試，皆與柏格氏平衡量表及步速等有顯著相關（r介於0.50與0.70），靜態平衡兩項測試，皆與坐到站所需時間有顯著相關(r=0.565，r=0.443)，而姿體晃動度另與柏格氏平衡量表得分數、最大位移量等有顯著相關(r=0.581；r=0.518)。討論與結論：平衡測試常因目的不同而有不同類之測試。而各類測試中，以柏格氏平衡量表、動態平衡以及步速和其他測試項目的相關性最多，顯示其對於患者功能性平衡表現最具廣泛性；另一方面，功能性前伸距離、靜態平衡測試和其他測試項目間較無關聯，可能是測試具專一化之意義，以及在該測試項目中所展現之能力並不影響其他方面的進展與表現。（物理治療2003;28(3):139-146）

Background and Purposes: Balance performance tests are important for assessing the abilities in daily livings. The purpose of this study was to investigate the correlations among different balance tests. Methods: Thirty-nine outpatients with hemiparesis secondary to stroke participated in this study. Static balance control-posture sway and symmetry, dynamic balance control-maximal excursion and directional control, forward reach distance, and functional mobility-transfer time during sit-to-stand, Berg Balance Scale and gait speed were measured to quantify individuals' performance. Pearson product-moment r test was used for statistical analysis, and significant level was set at 0.05. Results: Berg Balance Scale score and gait speed were noted to have moderate correlations with other tests r range 0.30-0.70, and forward reach distance only had low correlations with the gait speed and Berg Balance sale score (r=0.35, 0.32). Dynamic balance control had moderate correlations r range 0.30-0.70 with other tests, but had no significant correlations with posture sway and symmetry. Conclusions: Berg Balance Scale score, gait speed, maximal excursion and directional control correlated with each other significantly, which may indicate the same possible mechanisms underlying functional mobility and dynamic balance control. However, there are fewer correlations between static balance control and other tests except for the transfer time during sit-to-stand. These might be different specific mechanisms underlying these tests. (FJPT 2003;28(3):139-146)
