背景與目的：恢復上肢的動作及功能是中風個案的首要任務之一，尤其是手部動作。電腦遊戲訓練對於中風復健有初步成效，但鮮少探討其在手部功能效果。本研究檢視一套上肢動作電腦遊戲系統(ReJoyce upper extremity workstation)於中風個案的手部功能之訓練成效。方法：採單盲隨機控制試驗，32位中風個案隨機分配至使用ReJoyce的實驗組(n = 17)及接受傳統治療的控制組(n=15)。受試者各進行每週二次，每次30分鐘，共12次的訓練，並於訓練前後接受測驗。使用二因子混合變異數分析(two-way mixed ANOVA)來檢驗兩組在各評量指標的變化。結果：在患側握力及上肢功能研究量表(Action Research Arm Test)的捏分項表現和總分皆有顯著組別和時間交互作用(p < .05)，並達到中效應值以上(partial η² > 0.13)。單純效果分析發現，實驗組的前後測比較，在這些指標皆有顯著進步(p = .001)；反之，控制組未有明顯進步。於傅格梅爾動作評量表(Fugl-Meyer Assessment)，未發現顯著的組別與時間交互作用，但具有顯著的組內之時間效果(p < .001)。

Background and purpose: Recovering the movement and function of the upper limbs, especially the hand function, is one of the critical treatment goals for stroke survivors. This study examined the effect of a computer game-based training program (ReJoyce upper extremity workstation) on hand function for stroke survivors. Methods: A single-blind randomized controlled trial was used. Thirty-two participants with stroke were randomly assigned to either the experimental group (n=17) using the ReJoyce or the control group (n=15). Each group performed for 30 minutes a session, two sessions a week, for 12 sessions in total. Each participant was administered with pre- and post-test. A two-way mixed ANOVA was used to examine the changes between the two groups. Results: Significant group by time interactions (p<.05) with moderate effect size (partial η2 > 0.13) were noted for grip strength of the affected side, and pinch subscore and total score of the Action Research Arm Test. The simple effect tests revealed that the experimental group improved substantially between the pre- and post-test; in contrast, the control group did not show obvious improvement. Time effect (p< .001) was noted for the Fugl-Meyer Assessment, but not the between-group or interaction effect. Conclusion: This study supports that compared with conventional training, the computer game-based training (e.g., ReJoyce) could result in significantly better outcomes on the grip strength of the affected side and hand function. Future studies may include stroke survivors with different characteristics and increase the sample size to validate the findings of this study.
