背景與目的：近來在國際上包含兒童動作發展、物理治療、適應體育運動等領域，動作發展協調障礙(Developmental coordination disorder; DCD)是十分熱門的研究主題，但在台灣，這方面的研究正在起步中。本篇研究目的在於探討台灣地區不同年齡層或不同性別學童其動作發展協調障礙的盛行率，且其在兒童動作評估量表(Movement Assessment Battery for Children (Movement ABC))之動作測驗項目表現上之特性。方法：本研究於台灣地區北、中、南共十個學校隨機篩檢597名學童(316名男生、281名女生)，所有參與篩檢之學童並無智力及肢體障礙之問題，年齡層為七歲(270名學童)到八歲(327名學童)。結果：本研究共篩檢出疑似動作發展協調障礙學童58人(9.7%)、動作發展協調障礙學童21人(3.5%)，其中七歲學童動作發展協調障礙的盛行率為4.81%，八歲學童的盛行率為2.44%，男女的發生比例為1.2：1。在兒童動作評估量表測試之手部操作靈活度及平衡能力項目，均是女生比男生表現優異；而在球類技巧能力上，除了八歲族群中男女無顯著的差異外，七歲族群及全體族群均是男生表現比女生好。所有項目中，八歲的學童表現均比七歲的學童優異。結論：以上結果能夠提供台灣地區七、八歲學童動作發展協調障礙的盛行率及動作特性概略的了解，未來可應用此結果到相關研究的拓展與比較。

Background and Purpose: Recently, Developmental Coordination Disorder (OCD) has been an essential topic in the fields of motor development of pediatrics, physical therapy, and adapted physical activity in the world. However, the characteristics of the DCD group in Taiwan have seldom been examined. The purpose of this study was to use the Movement Assessment Battery for Children (Movement ABC) to evaluate children and determine whether they have movement difficulties in Taiwan, and also to compare age and gender differences in the prevalence of motor coordination. Methods: Five hundreds and ninty-seven children (316 boys and 281 girls) with age between 7 and 8 years old were evaluated All of them were physically and intellectually normal. Results: Fifty-eight children (9.7 %) were identified as borderline DCD children and 21 children (3.5%) were identified as DCD. The prevalence rate of children with DCD was 4.81 % in 7 years old, and 2.44% in 8 years old. In the DCD group, the ratio between boys and girls was 1.2: I. In the testing items, girls' performances in the manual dexterity and balance were better than those of boys. However, in the ball skills, boys performed better than girls. In all testing items, 8 year-old children performed better than 7 year-old children. Conclusion: Based on the results, the prevalence of DCD children in 7 to 8 year-old children and the characteristics of motor performance of the 7 to 8 year-old children in Taiwan were identified. The results of this study may be used to compare with related studies in the future.
