Limited knowledge exists regarding whether transcutaneous electrical stimulation (TES)-based exercise can improve the lingual pressure generation.
To compare the effect of submental TES with two different pulse durations (PD) coupled with isometric lingual exercises on lingual pressure measures.
Twenty-eight healthy volunteers were divided into two submental TES groups: short PD (300 μs) and long PD (700 μs). The Iowa Oral Performance Instrument (IOPI) was used for lingual pressure measurements and exercise. In total, participants attended six exercise sessions 3 days per week for 2 consecutive weeks. Maximum and swallowing lingual pressures were measured 1 h following each exercise session and 3 days after the final session to assess any detraining effect. Data were analysed using repeated measure ANOVA.
Mean maximum lingual pressure change was significantly greater in TES with short PD versus the long PD condition following the first week of exercise. Following the 2-week exercise, a significant increase was found in mean maximum lingual pressure for short and long PD conditions compared with the baseline. However, no significant difference was found between PD conditions for maximum lingual pressure. Likewise, no significant differences in swallowing lingual pressure were found compared with the baseline or across the two TES conditions.
Although short PD induced greater gain in maximum lingual pressure than the long PD after week 1, the enhanced effect faded after week 2, leading to a comparable increase in maximum lingual pressure for both groups. However, increased gain in maximum lingual pressure was not transferred to lingual pressure during swallowing.
关于基于经皮电刺激（TES）的运动是否能改善舌压产生，目前知识有限。
比较两种不同脉冲持续时间（PD）的颏下 TES 与等长舌肌运动相结合对舌压指标的影响。
将 28 名健康志愿者分为颏下 TES 短 PD（300 μs）和长 PD（700 μs）两组。采用爱荷华口腔表现仪器（IOPI）进行舌压测量和运动。参与者总共参加 6 次运动，每周 3 次，连续 2 周。每次运动后 1 小时和最后一次运动后 3 天测量最大和吞咽舌压，以评估任何脱训效应。使用重复测量方差分析对数据进行分析。
与长 PD 条件相比，短 PD 条件下 TES 运动第一周后最大舌压变化的平均值显著更大。经过 2 周的运动，与基线相比，短 PD 和长 PD 条件下的最大舌压平均值均显著增加。然而，在最大舌压方面，PD 条件之间没有发现显著差异。同样，与基线或两种 TES 条件相比，吞咽舌压没有发现显著差异。
尽管在第 1 周后短 PD 引起的最大舌压增加大于长 PD，但第 2 周后增强效果消失，导致两组的最大舌压增加相当。然而，最大舌压的增加并没有转移到吞咽时的舌压上。
