The effect of palatal plate therapy on oral dysfunction in children with Down syndrome was studied during a 1-year period. Twenty-nine subjects with a mean age of 24 months were randomized to a test group or to a control group. The variables concerning orofacial muscle function--that is, "closed mouth', "tip of the tongue visible', "open mouth', "inactive protrusion of the tongue', and "active protrusion of the tongue'--were monitored by video recordings. After 12 months of therapy the mean duration of the factor "closed mouth' was significantly longer (p < 0.001) and "inactive protrusion of the tongue' significantly shorter (p < 0.001) in the test group than in the control group. The results indicate that in children with Down syndrome, palatal plate therapy may be a valuable complement to a training program for improving orofacial muscle function.
在为期1年的时间里，研究了腭板治疗对唐氏综合征患儿口腔功能障碍的影响。29名平均年龄为24个月的受试者被随机分为试验组和对照组。通过视频记录监测与口面部肌肉功能相关的变量，即“闭口”、“可见舌尖”、“张口”、“舌被动前伸”和“舌主动前伸”。治疗12个月后，试验组“闭口”因素的平均持续时间显著长于对照组（p < 0.001），“舌被动前伸”显著短于对照组（p < 0.001）。结果表明，对于唐氏综合征患儿，腭板治疗可能是改善口面部肌肉功能训练方案的一项有价值的补充。
