背景：我國尚未建立評估工具與學校教師之評估方式以快速且正確篩檢動作能力強之兒童或動作能力弱之發展協調障礙兒童，以致評量我國兒童的動作協調能力結果與實務應用仍缺乏一致性，同時也未有任何研究探討過我國原住民兒童之動作協調能力與身體活動。目的：此第三年延續性之研究計畫目的在於比較原住民兒童與非原住民兒童之動作協調能力，及比較發展協調障礙兒童與非發展協調障礙兒童在動作協調能力及活動量之差異，以了解兒童動作協調能力與活動量之關係，並同時比較原住民兒童與非原住民兒童之活動量差異。方法：本研究篩檢及觀察我國67名一般國小四年級至六年級男童（50位為非發展協調障礙兒童及17位為發展協調障礙兒童），及16名原住民國小男童，年齡分布於九至十二歲，用於兒童動作評估的國外工具為Movement ABC測驗，及我國之本土化評量工具台灣動作協調能力進行測驗，並使用RT3加速規記錄兒童七天活動量，以及使用兒童生活型態量表收集兒童之主觀性生活型態活動量。在動作協調能力、兒童生活型態量表數據及加速規之活動量結果，將計算彼此間的相關；以及比較發展協調障礙兒童與非發展協調障礙兒童，及比較原住民兒童與非原住民兒童在上述三項結果之差異。結果：本研究主要發現非發展協調障礙兒童明顯在七日身體活動量及動作協調能力優於發展協調障礙兒童。原住民兒童在七日身體活動量及動作協調能力明顯優於非原住民兒童。同時兒童活動量（無論是生活型態問卷結果或記錄的加速規結果）與動作協調能力有顯著的正相關。結論：經由本研究將直接有助於了解發展協調障礙兒童有動作協調能力及活動量不足的問題，原住民兒童在動作協調能力及活動量明顯優於非原住民兒童，以及初步建立原住民兒童動作協調能力與活動量之結果。
Background: There were no proper evaluation tools for PE teachers to quickly and appropriately examine children with or without DCD in Taiwan. Thus, the results of evaluating children in Taiwan are still lack of consistency. In addition, no research studies have examined motor coordination and physical activities of indigenous children in Taiwan. Purposes: The aims of this research project in Year three were to (a) compare motor coordination and physical activity (PA) of children with developmental coordination disorder (DCD) and non-DCD, (b) to compare motor coordination and PA of indigenous children and non-indigenous children and (c) to examine the relationships between motor coordination and PA of children. Methods: The Movement Assessment Battery for Children (Movement ABC) evaluation tool, the Taiwanese Movement Assessment (TMA) test were used to evaluate primary school students and indigenous children whose age ranges are from 9 to 12 years old. PA of 17 children with DCD, 50 children without DCD, and 16 indigenous children were analyzed through 7-day recording in RT3 accelerometer, and a children’s lifestyle questionnaire (CLQ). Results: Children with non-DCD in motor coordination and PA were significantly higher than children with DCD. Indigenous children in motor coordination and PA were significantly higher than non-indigenous children. Motor coordination was significantly correlation with PA and CLQ. Conclusion: The results of this study help us to identify the less motor coordination and PA of children with DCD. In addition, indigenous children have higher coordination ability and PA than non-indigenous children. This project also developed the preliminary data of motor coordination and physical activities in indigenous Taiwanese children.
