Abstract

Background

Tongue-strengthening exercises may be used at home to strengthen swallowing-related oropharyngeal muscles in community-dwelling older adults with sarcopenic dysphagia; however, evidence of their effectiveness remains unclear.

Objective

This study aimed to investigate the effects of a home-based tongue-strengthening exercise (hTSE) using portable tool on swallowing-related oropharyngeal muscles in community-dwelling older adults with sarcopenic dysphagia.

Methods

Forth community-dwelling older adults with sarcopenic dysphagia were enrolled in the study. The participants were randomly assigned to the experimental and control groups. 1-Repetition Maximum (1-RM) of tongue muscle was measured in the experimental group using the Iowa Oral Performance Instrument, and hTSE was performed using a portable tool with an intensity corresponding to approximately 70%–80% of the range based on the 1-RM value (90 times/day, 5 days/week, for 8 weeks). The control group did not perform any tongue exercises. The primary outcome measures were tongue strength and thickness. The secondary outcome measure was suprahyoid muscle strength (digastric and mylohyoid muscles).

Results

The experimental group showed significantly greater increases in suprahyoid muscle (mylohyoid and digastric) thickness (p = .01 and .011, d = 1.0 and .55), as well as tongue strength and thickness (p < .001 and .029, d = 2.2 and .6) than the control group.

Conclusion

This study confirmed that hTSE using a portable tool is effective in increasing swallowing-related oropharyngeal muscle activity in older adults with sarcopenic dysphagia. Therefore, hTSE is recommended as an inexpensive, safe, and easy-to-use therapy for sarcopenic dysphagia in older adults.

一项随机对照研究：使用便携式工具在家中对患有肌肉萎缩性吞咽困难的老年人的口咽肌肉进行舌头强化训练的效果。

背景：对于患有肌肉疏松性吞咽困难的社区居住老年人，可在家中进行舌部强化训练，以增强与吞咽相关的口咽肌肉；然而，其有效性的证据仍不明确：本研究旨在探讨使用便携式工具在家中进行舌部强化训练（hTSE）对患有肌肉疏松性吞咽困难的社区老年人吞咽相关口咽肌肉的影响：研究对象为患有肌肉疏松性吞咽困难的社区老年人。参与者被随机分配到实验组和对照组。实验组使用爱荷华州口腔能力测试仪测量舌肌的1-重复最大值（1-RM），并使用便携式工具进行hTSE训练，训练强度约为1-RM值范围的70%-80%（90次/天，5天/周，持续8周）。对照组不进行任何舌头练习。主要结果指标为舌头的力量和厚度。次要结果指标是舌上肌力（舌骨肌和舌骨肌）：结果：实验组的舌上肌（肌舌肌和掘舌肌）厚度明显增加（p = .01 和 .011, d = 1.0 和 .55），舌的力量和厚度也明显增加（p 结论：实验组的舌上肌（肌舌肌和掘舌肌）厚度明显增加（p = .01 和 .011, d = 1.0 和 .55）：本研究证实，使用便携式工具进行 hTSE 可以有效提高患有肌肉疏松性吞咽困难的老年人吞咽相关口咽肌肉的活动能力。因此，建议将 hTSE 作为治疗老年人肌肉疏松性吞咽困难的一种廉价、安全且易于使用的疗法。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
