Sarcopenia, defined as a decline in muscle mass and function related to aging, affects both limb and swallowing-related muscles. Sarcopenic dysphagia is characterized by decreased swallowing function; therefore, early detection of subclinical dysphagia and subsequent intervention appear to be crucial in the elderly. Numerous tools have been employed to measure the function, strength, and mass of swallowing-related muscles in sarcopenic elderly. The swallowing function can be evaluated by questionnaires like Eating Assessment Tool, Functional Oral Intake Scale, and Food Intake Level Scale, and tests such as the modified water swallowing test and videofluoroscopic swallowing study. Surface electromyography and high-resolution manometry can be applied for quantifying swallowing-related muscle strength. Modalities such as ultrasonography and magnetic resonance imaging are capable of estimating the swallowing muscle mass. In patients with sarcopenic dysphagia, a thorough assessment should be given followed by an integrated intervention combining swallowing muscle strengthening, nutrition support, food texture modification, physical, and occupational therapies. This article aimed to comprehensively summarize the diagnostic criteria/tools as well as their associations/performance in sarcopenic dysphagia. The intervention strategy will also be narrated in this review.

“…Based on previous geriatric skeletal studies, intramuscular fatty infiltration is considerably more rapid than concomitant muscle atrophy 28 ; this ageing-associated change occurs in the tongue muscle as well. 2 From these findings, we speculated that the age-related initial deterioration of articulation is associated with low tongue motion caused by fatty infiltration. However, because of the insufficient evaluation of articulation, there is little evidence on which to base this hypothesis.…”

“…Because the tongue muscle is an important organ for articulation and swallowing, the evaluation of tongue muscle function is important in the clinical setting. Tongue muscle function has often been evaluated as tongue pressure using devices such as the JMS tongue pressure measurement device, [1][2][3][4][5][6] the Iowa Oral Performance Instrument [7][8][9] and the tongue pressure sensor sheet system. 10,11 Among these devices, the JMS tongue pressure measurement device and Iowa Oral Performance Instrument are frequently used in both study and clinical settings, likely because of their measurement convenience as compared with the other device.…”

“…The main purpose of this study was to investigate the reliability of tongue pressure waveform analysis using the JMS tongue pressure measurement device and to compare the rate of tongue force development with articulation and tongue muscle composition. Furthermore, some studies 2,22 have reported that tongue muscle fatty infiltration is a characteristic of age-related tongue muscle composition changes, and this can adversely affect swallowing function. However, the impact of tongue muscle composition on articulation has not been fully elucidated because only few studies focussed on this topic.…”

Background: Rate force development is associated with performance and muscle composition in whole-body muscle. Although rate force development on tongue muscle can be examined using tongue pressure waveform, there have been only few investigations on this topic.Objectives: This study's main purpose was to investigate the reliability of tongue pressure waveform analysis and its relationship with articulation and tongue muscle composition. In addition, we also investigated the association between tongue muscle composition and articulation.Methods: Forty-five community-dwelling individuals aged >20 years participated.We analysed tongue pressure waveform, including maximum tongue pressure (MTP), time to peak, mean rate of tongue force development and peak rate of tongue force development (PRTFD). We also assessed oral diadochokinesis. Magnetic resonance imaging of the tongue provided data on tongue muscle composition, including tongue volume, fat mass, lean muscle mass and fat percentage. We evaluated the reliability of tongue pressure waveform analysis. Moreover, we examined the coefficients between tongue pressure waveform analysis, oral diadochokinesis and tongue composition. Results:We detected a high reliability of MTP and PRTFD. MTP and PRTFD were significantly correlated with tongue muscle composition. MTP was not significantly correlated with oral diadochokinesis. PRTFD was significantly positively correlated with oral diadochokinesis. Tongue fat mass and fat percentage were negatively correlated with oral diadochokinesis of /ta/ and /ka/.Conclusions: Peak rate of tongue force development is a highly reliable method for tongue pressure analysis and is useful for elucidating the functional importance of tongue muscle function on articulation. We speculated that fatty infiltration of the tongue adversely affects articulation.

“…Traditional dysphagia treatment includes oral facial massage,6 thermal tactile stimulation7 and various compensatory methods 8 9. Although they can help patients begin to attempt oral feeding promptly, they do not facilitate the recovery of neural networks in regions of the cerebral cortex associated with swallowing, and training efficacy is short-lived 10–12. Modalities for improving oropharyngeal muscle strength such as tongue-to-palate resistance training (TPRT),13 Shaker exercise,14 Iowa Oral Performance Instrument (IOPI),15 tongue-strengthening exercises (TSEs)16 and chin tuck against resistance (CTAR) exercise17 use isometric or isokinetic muscle contractions to improve the strength and endurance of swallowing-related muscles.…”

IntroductionDysphagia is a common functional disorder after stroke. Most patients post-stroke are incapable of oral feeding, which often leads to complications such as malnutrition, aspiration pneumonia and dehydration that seriously affect the quality of life of patients. Oropharyngeal muscle strength training is a major method of swallowing training, and recent studies have focused on healthy adults, elderly persons, and patients with head and neck cancer or neurodegenerative diseases; but there have been few studies on such training in patients with post-stroke dysphagia. Our study aims to systematically review the safety and performance of oropharyngeal muscle strength training in the treatment of post-stroke dysphagia during oral feeding.Methods and analysisThe Cochrane Library, Web of Science, PubMed, Embase and ClinicalTrials.gov databases will be systematically searched, and all relevant articles in English from the establishment of the databases to January 2022 will be reviewed. The study will be conducted in accordance with the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions and will be reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines. The primary outcome measures include the Penetration–Aspiration Scale and the Functional Oral Intake Scale. Two authors will independently screen the articles, extract the data and assess the study quality. Any disagreements during this process will be resolved by discussion or by consultation with a third author. Next, quantitative or qualitative, subgroup and sensitivity analyses of the included literature data will be performed as appropriate.Ethics and disseminationEthical approval is not required for this systematic review as no primary data collection will be required. The results of the present study will be published in a peer-reviewed journal in the field of deglutition disorders.PROSPERO registration numberCRD42022302471.
