Trisomy 18 (T18) is a congenital genetic disease that causes multiple impairments, mainly in motor functioning. Few studies have investigated behavioral interventions with individuals with T18. In the current study, we tested an intervention to teach basic motor responses to a 30-month-old boy with T18. He had severe hypotonia and emitted only a few uncoordinated movements of his head and arms. We taught him a grasping response using a manual guidance procedure that included repeating the movement with full manual guidance 30 consecutive times and then recording independent responses. We then taught turning the page of a book, pressing a button on a toy, and hammering responses, sequentially, using an adapted version of the same procedure within a multiple-probe design. The participant learned each target response at a progressively faster rate. We discuss the potential use of this procedure for children with T18 and other severe motor restrictions.

教授 18 三体儿童的运动反应：一项初步研究

18 三体 (T18) 是一种先天性遗传病，会导致多种损伤，主要是运动功能障碍。很少有研究调查对 T18 患者的行为干预。在目前的研究中，我们测试了一项干预措施，以教一个 30 个月大的 T18 男孩的基本运动反应。他有严重的肌张力减退，头部和手臂只有几次不协调的动作。我们使用手动引导程序教他抓握反应，包括连续 30 次以完全手动引导重复动作，然后记录独立反应。然后，我们教在多探针设计中使用相同程序的改编版本，依次翻书、按下玩具上的按钮和敲击响应。参与者以越来越快的速度学习每个目标响应。
