Early oral function therapy by using palatal plate and Dohsa-hou method to infants with Down Syndrome

大多数患有唐氏综合症的婴儿通常不能闭嘴和缩舌头。我们尝试用Castillo Morales的腭板和练习Dohsa-Hou方法来验证口腔功能治疗的效果以及咬合与体位的关系。戴上腭板后，他们可以立即闭上嘴，缩回舌头。但随着他们的成长，这些口腔功能在进食和饮酒以及休息时间都不稳定。我们认为最好增加与吞咽有关的直接和/或间接治疗。他们有独特的身体姿势，如驼背的肩膀，前腹部和向后弯曲的膝盖。道萨-侯法的锻炼改善了他们的身体姿势。但下颌前突仍然存在。为了研究咬合与体位的关系，研究对象为健康成人。因为对唐氏综合症的婴儿来说，手术非常困难。虽然个体偏差较大，但有意识地改变重心与咬合中心定向的符合率为50~75%。少数唐氏综合征患者较健康成人有重心移动较大、咬合压力较小的趋势。

Most of infants with Down syndrome can't close their mouths and retract their tongues usually. We attempted to prove the effects of oral function therapy by using the palatal plate of Castillo Morales and exercising Dohsa-hou method and the relationship between occlusion and body posture. Immediately after they wore the palatal plate, they can close mouths and retract tongues. But as they grew up, these oral functions were not stabilized at eating and drinking time as well as resting time. We think we had better add the direct and/or indirect therapy concerning to the deglutition. They have characteristic body posture as stooped shoulders, prutrudent abdominal region and bend backward knees. The exercise of Dohsa-hou method improved on their body posture. But mandibular protrusion still remained. To examine relationship between occlusion and body posture, healthy adults were used. Because it was very difficult for infants with Down syndrome on, the cooperation. Though the individual deviations were larger, the agreement rates of the derection of changing the center of gravity consciously with the center of occlusion were 50-75%. A few adults with Down syndrome had a tendency to exhibit the larger movement of center of gravity and the smaller pressure of occlusion than these of healthy adults.
