肌肉力量和功能一般与肌肉量呈正相关，与肌肉质量呈负相关；然而，舌头表现出一种独特的倾向，不同于肢体肌肉。舌头各部分的特征、肌肉力量和功能与全身因素之间的关系尚不清楚。本研究旨在探讨舌中、舌底横断面积（CSA）和回声强度（EI）与吞咽、发音功能和身体组成的关系。89名健康个体参与了这项横断面研究。吞咽评估使用舌压（TP）和下颌张开力（JOF），因为它们表明吞咽相关的肌肉力量。通过口腔diadochokinesis （ODK）评估发音功能。体组成进行生物电阻抗分析。采用超声测量舌中、舌底csa和ei。采用多元回归分析检验舌头特征、吞咽相关肌肉力量与ODK之间的关系。在以TP为因变量的多元回归分析中，年龄（beta = - 0.22, P < 0.01）和中部CSA （beta = 0.02, P < 0.01）为显著解释变量。在以JOF为因变量的多元回归分析中，性别（beta = - 2.76, P < 0.01）和基数CSA （beta = - 0.004, P < 0.05）是显著的解释变量。以衔接函数为因变量的多元回归分析结果不显著。舌头的CSA是一个比EI更好的吞咽相关肌肉力量指标。超声检查可用于评估与吞咽有关的肌肉力量。
Muscle strength and function are generally positively correlated with muscle quantity and negatively correlated with muscle quality; however, the tongue shows a unique tendency, different from limb muscles. The relationship between the characteristics of each part of the tongue, muscle strength and function, and systemic factors has been unclear. The aim of the study was to investigate the relationship between cross-sectional area (CSA) and echo intensity (EI) of the middle and base of the tongue and swallowing, articulation function, and body composition. Eighty-nine healthy individuals were included in this cross-sectional study. Swallowing was assessed using tongue pressure (TP) and jaw opening force (JOF) as they indicate swallowing-related muscle strength. Articulation function was evaluated through oral diadochokinesis (ODK). Bioelectrical impedance analysis was performed for body composition. CSAs and EIs of the middle and base of the tongue were measured using ultrasound. Multiple regression analysis was used to examine the relationship between the characteristics of the tongue, swallowing-related muscle strength, and ODK. In multiple regression analysis with TP as the dependent variable, age (beta = - 0.22, P < 0.01) and CSA of the middle part (beta = 0.02, P < 0.01) were significant explanatory variables. In multiple regression analysis with JOF as the dependent variable, sex (beta = - 2.76, P < 0.01) and CSA of the base (beta = - 0.004, P < 0.05) were significant explanatory variables. Multiple regression analysis with articulation function as the dependent variable did not yield significant results. The CSA of the tongue is a better indicator of swallowing-related muscle strength than EI. Ultrasonography may be used for assessing swallowing-related muscle strength.
