[Purpose] The aim of this study was to measure and compare the maximal tongue strength and tongue strength used during swallowing in young and older adults. [Subjects and Methods] The study recruited 80 healthy young (aged 20 to 39 years) and older adults (aged ≥65 years) in public places. The Iowa Oral Performance Instrument was used to measure maximal tongue strength and tongue strength used during swallowing. For each subject, the peak value of three measurements was recorded and analyzed. [Results] Maximal tongue strength was statistically significantly higher for the young adults group than the older adults group. Conversely, tongue strength used during swallowing was statistically significantly higher for the older adults group than the young adults group. The percentages of tongue strength used during swallowing for the young adults and older adults groups were approximately 38.8% and 53.8%, respectively. [Conclusion] This study confirmed that older adults have a lower maximal tongue strength than young adults, but a higher tongue strength used during swallowing.
[目的] 本研究旨在测量并比较年轻人和老年人吞咽时的最大舌肌力及舌肌力。[对象与方法] 本研究在公共场所招募了80名健康年轻人(20至39岁)和老年人(≥65岁)。使用爱荷华口腔功能测量仪测量最大舌肌力及吞咽时的舌肌力。对每位受试者记录并分析三次测量的峰值。[结果] 年轻人组的最大舌肌力在统计学上显著高于老年人组。相反,老年人组吞咽时的舌肌力在统计学上显著高于年轻人组。年轻人组和老年人组吞咽时使用的舌肌力百分比分别约为38.8%和53.8%。[结论] 本研究证实,老年人的最大舌肌力低于年轻人,但吞咽时的舌肌力较高。
