摘要

隨著人機介面的進步，觸控介面已逐步在生活中佔了一席之地。以任務導向概念結合電腦化觸控螢幕訓練系統已完成開發並可用於提供中風患者上肢復健。然而該系統內建的活動項目評估之信度及與效度仍有待驗證。據此，本研究的目的為一、調查中風個案使用電腦螢幕觸控式上肢訓練系統之動作表現分數的信度(reliability)；二、比較分析此系統與其它標準化上肢功能評估工具之間的相關性來驗證效標關聯效度(criterion-related validity)。30位中風個案分別依電腦隨機分配順序接受手臂動作調查測試量表、傅格梅爾動作評量表、積木與盒子測驗、及手握力測試共四種臨床標準化上肢功能評估工具施測，及執行十項內建於電腦螢幕觸控式上肢訓練系統的活動。結果發現電腦螢幕觸控式上肢訓練系統之十分項活動彼此之間具有良好內在一致性信度，克隆巴赫係數(Cronbach's alpha)達到0.87，且活動再測信度高，級內相關係數範圍分布皆在0.76～0.96之間。與四個標準化評估工具之效標關聯效度達到中度至高度相關。本研究結果支持中風個案使用電腦螢幕觸控式上肢訓練系統具良好之再測信度且能評估手功能表現。

Because of progress made in human-machine interfaces, touchscreens increasingly play a key role in daily living. A task-oriented concept combined with a computerized touchscreen training system was developed and used to facilitate upper limb rehabilitation after stroke. However, the reliability and validity of the activity items within the system required further verification. Therefore, the aims of this study were 1) to examine the reliability of scores for the activity items when patients with stroke used this device and 2) to verify criterion-related validity by analyzing the relationship between scores from this device and other standard upper limb functional assessments. Thirty eligible patients with stroke participated in this study. Using a computer-generated random order, participants were randomly assigned to complete four clinical standard upper limb functional assessments: the action research arm test, Fugl-Meyer assessment, box and block test, and hand grip strength test. Thereafter, participants were asked to perform 10 built-in activity items by using the touchscreen system for the upper limbs. Results indicated that the scores for the 10 items had high internal consistency (Cronbach's α = 0.87). The intraclass correlation coefficient (ICC) ranged from 0.76 to 0.96, indicating high test-retest reliability. The criterion-related validity showed a moderate to high correlation between scores from this device and the four standard upper limb functional assessments. The results of this study indicated that this computerized touchscreen training system was reliable and could detect upper limb function performance in patients with stroke.
