本研究探讨了重复舌运动任务对舌骨上肌活动和舌压力的影响。14名参与者在连续五天的每一天进行了三个系列的标准化舌头提升训练（TLT）任务。记录舌骨上肌的肌电图（EMG）活动和舌压。在第一个和第三个TLT系列中，参与者只被指示针对不同的力量水平。在第二个TLT系列中，给出了力水平的视觉反馈。一个系列包括三个测量值[分别为最大自主收缩（MVC）的10%、20%和40%]。根据所有系列计算目标力水平-EMG曲线和目标力水平-舌压曲线的决定系数。在MVC期间，EMG均方根（RMS）值和舌压无统计学显著性日间差异。在第1天的第一个系列中的舌压的决定系数在统计学上显著低于第5天的第一个系列中的决定系数。这些结果表明，舌头压力的控制得到改善，而最大的力量保持不变。这些结果可能对舌功能受损患者（如吞咽障碍或吞咽困难）的学习相关治疗模式产生影响。
This study investigated the effect of repeated tongue motor tasks on suprahyoid muscle activity and tongue pressure. Fourteen participants performed three series of a standardized tongue‐lift training (TLT) task on each of five consecutive days. Electromyographic (EMG) activity from suprahyoid muscles and tongue pressure were recorded. In the first and third TLT series, participants were instructed only to target different force levels. During the second TLT series, visual feedback of the force level was given. One series consisted of three measurements [at 10%, 20%, and 40% of maximum voluntary contraction (MVC), respectively]. The coefficient of determination of the target force level–EMG curve and the target force level–tongue pressure curve was calculated from all series. There were no statistically significant day‐to‐day differences in EMG‐root mean square (RMS) values and tongue pressure during MVC. The coefficients of determination of tongue pressure in the first series on day 1 were statistically significantly lower than the coefficients of determination in the first series on day 5. These findings suggest that the control of tongue pressure improved, while the maximum force remained constant. These results could have implications for treatment paradigms related to learning for patients with compromised tongue function, such as swallowing disorders or dysphagia.
