目的，探測以工作為取向之物理治療對發展性協調障礙兒童(Development Coordination disorder, DCD)之療效及了解「嬰幼兒綜合發展量表」對DCD兒童治療成效之反應度。方法：本研究之三位個案年齡範圍由三歲一個月至四歲十一個月。第一位個案接受每週一次、每次40-50分鐘的團體治療（共5名兒童參加），為期三個月。第二位及第三位個案一起接受每週一次，每次30-60分鐘之物理治療，持續兩個月。在治療前後及治療期間分別以「嬰幼兒綜合發展量表」來測量三名個案的進步狀況。結果：三位個案在第一次「嬰幼兒綜合發展量表」「動作」領域中的粗動作發展商數均明顯落後於認知能力。經過治療後，三位個案在「動作」及「社會」領域的發展年齡均較其他領域明顯進步，其中「動作」領域之發展年齡接近或超過其「認知」之發展年齡。結論：給予本研究中之三位DCD兒童以工作取向為主的動作訓練及相關的物理治療計畫確實能提升其動作功能，同時也能增進其社會性的表現。此外，利用具有國內常模之「嬰幼兒綜合發展量表」能表現出物理治療對本研究中三位兒童接受2-3個月治療介入後之療效反應性。

Purposes: The purposes of this study were to examine (1) the effects of physical therapy with task oriented approaching method on children with developmental coordination disorder (DCD), and (2) the responsiveness of Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT) used as an evaluation tool for children with DCD. Methods: 3 cases with DCD aged from 3 years and 1 month to 4 years and 11 months were studied. The developmental ages (DAs) of CDIIT were used to measure the outcome of the 3 cases. Physical therapy program for the case 1 lasted 3 months (1 session every week and 40-50 minutes every session), the program for the cases 2 and 3 lasted 2 months (1 session every week and 30-60 minutes every session). The case 1 joined a group therapy program with 5 children in the group. The other two cases were treated together with the other program. Results: The results of CDIIT tested at the beginning showed that all the cases had lower DQs in the motor domain (especially in the gross motor subdomain) than in the cognition domain. They showed improvement in the developmental age in motor and social domains of CDIIT after physical therapy intervention. All 3 cases had higher or equal DAs in motor domains than that in the cognitive domain after treatment. Conclusion: The physical therapy program with task oriented method designed for the children with DCD can effectively improve motor ability of these children. The children with DCD also had greater abilities in dealing with social problems after physical therapy intervention In addition, the CDIIT with the norms in Taiwan is a responsive evaluative tool for assessing children with DCD.
