To assess the electrical activity of the suprahyoid muscle and the tongue pressure in a two-wing program of tongue strengthening in individuals with Parkinson's disease (PD).
A pre-post-detraining design study included sixty PD patients assigned to two groups randomly. The experimental group (EG) performed tongue isometric pressure exercises using the Iowa Oral Performance Instrument with an increasing scheme of 5% load weekly and traditional tongue therapy for 8 weeks. The control group (CG) performed only traditional therapy. The electrical activity of suprahyoids was measured using surface electromyography (sEMG) during tongue-to-palate pressure. Four selected domains of the Swallowing Quality of Life Questionnaire (SWAL-QOL) mostly related to tongue strength were considered.
The experimental group showed increased sEMG values of suprahyoid muscles reaching statistically significant difference at the fourth week of tongue training, while the control did it at the eighth week. Experimental group showed significant improvements in tongue strength (d = 2.128; p = 0.000). Only controls showed detraining effect. Statistically significant difference within groups were found in one and three dimensions of the SWAL-QOL in the CG and EG, respectively.
Analysis of electrical activity on suprahyoids muscles provided a better understanding of the changes underlying the outcomes of tongue strength gains obtained through a combined tongue strengthening exercises protocol in PD. Such protocol led not only to increased tongue strength but also to a better perceived swallowing function in PD subjects.
评估帕金森病（PD）患者在一项双侧舌肌强化训练方案中舌骨上肌群的电活动和舌压力。
一项训练前-训练后-去训练设计研究，随机将60名PD患者分为两组。实验组（EG）使用爱荷华口腔功能仪器进行舌等长压力练习，每周负荷增加5%，并进行传统舌肌治疗，为期8周。对照组（CG）仅进行传统治疗。在舌抵上颚压力过程中，使用表面肌电图（sEMG）测量舌骨上肌群的电活动。考虑了吞咽生活质量问卷（SWAL-QOL）中四个主要与舌力量相关的选定领域。
实验组在舌训练第4周时舌骨上肌群的sEMG值增加，达到统计学显著差异，而对照组在第8周时达到。实验组舌力量有显著改善（d = 2.128；p = 0.000）。只有对照组显示出去训练效应。在CG和EG中，分别在SWAL-QOL的一个和三个维度上发现了组内统计学显著差异。
对舌骨上肌群电活动的分析有助于更好地理解通过联合舌肌强化训练方案在PD患者中获得舌力量增加结果背后的变化。这样的方案不仅导致PD患者舌力量增加，还使其吞咽功能得到更好的感知。
