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. [ABSTRACT FROM AUTHOR]

Background: Early identification of penetration/aspiration (P/A) risk in older adults with sarcopenia is crucial to prevent complications and maintain quality of life., Purpose: To evaluate the diagnostic utility of orofacial muscle strength measurements for predicting the risk of P/A in older adults with sarcopenia., Methods: In this observational and prospective study, we collated consecutive data from community-dwelling older adults diagnosed with sarcopenia at a musculoskeletal disorder clinic. Altogether, 54 participants underwent orofacial muscle strength measurements (the index test) using the Iowa Oral Performance Instrument and a videofluoroscopic swallowing study (VFSS) (the reference test) to evaluate for the presence of P/A. Receiver operating characteristic (ROC) curve analysis was performed to determine orofacial muscle strength based on P/A., Results: Overall, 34 patients showed penetration in the VFSS, although none of the patients showed signs of aspiration. The cut-off for tongue strength to identify the risk of P/A was ≤ 20.5 kPa, with a sensitivity and specificity of 0.75 and 0.74, respectively; the area under the curve (AUC) was 0.88. The cut-off for buccinator strength was ≤ 19.5 kPa, with a sensitivity and specificity of 0.65 and 0.68, respectively, with an AUC of 0.69. The cut-off for lip muscle strength was ≤ 18.5 kPa, with a sensitivity and specificity of 0.65 and 0.71, respectively, with an AUC of 0.69., Conclusion: The evaluation of buccinator and lip muscle strength did not demonstrate sufficient diagnostic utility for detecting the risk of P/A in older patients with sarcopenia; however, tongue strength showed reliable diagnostic utility for identifying the risk of P/A., (© 2025 John Wiley & Sons Ltd.)
