Oral motor function was evaluated after 4 years of palatal plate therapy in nine children with Down syndrome (DS); 11 children with DS constituted the control group. During the treatment period all children had orofacial physiotherapy with their speech pathologist. An extraoral examination was performed, as was a video registration of the face. Nine different variables showing positions of the lips, tongue, and facial expression were examined. Children in the palatal plate group (n = 9) had significantly more rounding lips during speech (P< 0.05) than children in the control group (n = 11). The active variables describing normal muscle tension were diagnosed to constitute 81.0% +/- 11.0% of the registered video time in the palatal plate group, compared with 68.2% +/- 22.5% in the control group. Statistically significant differences were found between the groups in the summary variables describing an inactive open mouth and inactive tongue protrusion (P< 0.01). The results indicate that palatal plate therapy has a long-term effect on oral motor function.
对9名唐氏综合征（DS）患儿进行了4年的腭板治疗后，评估了他们的口腔运动功能；11名DS患儿组成了对照组。在治疗期间，所有患儿都与言语病理学家一起接受了口面部物理治疗。进行了口外检查以及面部视频记录。检查了9个显示嘴唇、舌头和面部表情位置的不同变量。腭板组（n = 9）的患儿在说话时嘴唇圆撅的情况显著多于对照组（n = 11）（P<0.05）。描述正常肌肉张力的活动变量在腭板组中占记录视频时间的81.0%±11.0%，而对照组为68.2%±22.5%。在描述不活动的张口和不活动的伸舌的汇总变量中，两组之间存在统计学上的显著差异（P<0.01）。结果表明，腭板治疗对口腔运动功能有长期影响。
