    • 使用手機時同時進行其他活動是我們現下最常見的雙重作業。此項研究探討對於大學生使用手機時的姿勢穩定度影響。以二十位大學生受測進行靜態和動態的姿勢穩定性測驗。使用測力板評估靜態姿勢穩定性；利用星狀平衡評估動態姿勢穩定性。使用壓力中心點(COP)、多尺度熵(MSE) 、以及多元多尺度熵 (MMSE) 分析靜態姿勢穩定性的資料。使用麥克沃曼時鐘測試(MCT)以及主觀評量表評估受測者的認知負荷。結果顯示(1)打字會影響姿勢穩定性、(2)試驗情境的變化並不會導致複雜度指標有明顯的改變、(3)執行雙重作業活動可以被看出是比較困難。

    Using a mobile phone while doing another activity is a common dual-task activity in our daily lives. This study examined the effect of using mobile phone on postural stability of college students. 20 college students were asked to perform static and dynamic postural stability tasks. Force platform was used to assess the static postural stability and the Star Excursion Balance Test (SEBT) was used to assess the dynamic postural stability. The static postural stability data were analyzed with traditional COP, multiscale entropy (MSE), and multivariate multiscale entropy (MMSE). The Mackworth Clock Test (MCT) and subjective rating scale were used to evaluate the cognitive load of the subjects. Results showed that (1) texting impaired postural stability, (2) the complexity index did not change much although the task conditions changed, and (3) performing dual-task activity is perceived to be more difficult.
