Change in oral function was evaluated longitudinally in elderly persons participating in an Exercises for Healthy Oral Function program implemented as part of the Long-Term Care Prevention Project. The participants comprised high-risk and healthy persons aged 65 yr or over. A questionnaire was used to classify them into two groups ('every day or sometimes' or 'rarely') at the end of the study for a comparison of change in repetitive saliva swallowing test (RSST) scores and oral diadochokinesis between 3 time points: at before, at immediately after, and at 1 yr after completion of the program. The average RSST score showed a decrease at 1 yr after intervention, but the difference was not statistically significant. Oral diadochokinesis showed a significant increase for all syllables upon completion of the program compared with at the beginning. This was followed by a significant decrease at 1 yr later compared with at the time of completion in the 'rarely' group for all syllables, but not in the 'every day or sometimes' group. In addition, the number of repetitions was significantly lower in the 'rarely' group than in the 'every day or sometimes' group for all syllables at 1 yr after completion. The results of the present study suggest that Long-Term Care Prevention Projects are necessary to maintain and improve oral function.
在参与作为长期护理预防项目一部分实施的健康口腔功能锻炼计划的老年人中，纵向评估口腔功能的变化。参与者包括65岁及以上的高危人群和健康人群。在研究结束时，使用问卷调查将他们分为两组（“每天或有时”或“很少”），以比较重复唾液吞咽测试（RSST）分数和口腔轮替运动在3个时间点（计划开始前、结束后立即、结束后1年）之间的变化。干预后1年，RSST平均得分有所下降，但差异无统计学意义。与开始时相比，计划完成时所有音节的口腔轮替运动均显著增加。随后，“很少”组在1年后所有音节与完成时相比显著下降，但“每天或有时”组没有。此外，完成后1年，“很少”组所有音节的重复次数显著低于“每天或有时”组。本研究结果表明，长期护理预防项目对于维持和改善口腔功能是必要的。
