“…Previous studies have reported that MTP declined with age, whereas ETP did not [15,31,34]. However, ETP decreased after meals in healthy adults [35] and with diseases such as Parkinson's disease [27] and amyotrophic lateral sclerosis [36]. Decreases in ETP have been suggested to affect the safety of swallowing [36].…”

Tongue-strengthening exercises (TSE) using a device have been proposed as an intervention for improving tongue strength and endurance. However, devices for TSE have been expensive and difficult to manipulate and are not commonly used in home or clinical settings. This study therefore aimed to investigate whether tongue-strengthening self-exercises (TSsE) using a tongue-strengthening self-exercise tool at home can improve tongue strength in healthy older adults. This study included 27 participants (exercise group, η = 16, 7 men, 9 women, median age 84.5 years; control group, n = 11, 2 men, 9 women, median age 79.0 years). Exercises in the exercise group consisted of pushing the anterior tongue against the hard palate 30 times, 3 times a day, 5 days a week, for 8 weeks using a tongue-strengthening self-exercise tool. This tool is available in five levels of hardness. The most suitable hardness of the tool for each participant was calculated based on 60% of maximum tongue pressure (MTP) during the first 2 weeks of the training period and 80% of MTP for the remainder of the training period, as assessed using a tongue pressure-measuring device. The exercise group showed a significant improvement of 4.1 kPa in MTP (an 11.53% increase) and 4.53 s in endurance of tongue pressure (ETP) (a 99.86% increase). Furthermore, adherence in the exercise group was 99.2%. In conclusion, performing TSsE for 8 weeks was effective for increasing MTP and ETP in healthy older adults. This indicates that TSsE may be useful in older individuals at home to prevent age-related tongue muscle weakness.

“…The performance of tongue strength is considered the main driving force for moving the bolus during the chewing and swallowing of food. Swallowing efficacy and safety may worsen due to muscle fatigue and weakness of the swallowing-related tongue muscles as a result of repetitive swallowing during a long meal time over 30 min [ 10 , 13 ]. Due to the development and progress of science, the strength of the tongue muscle can be measured via a mechanical pressure device exerted by the tongue against the hard palate.…”

“…Over the past three decades, tongue muscle strength has been used as a useful indicator to evaluate the physically frail, the eating and swallowing ability of the elderly, to screen patients with or without penetration, aspiration, or residue during eating, and assist patients (such as those with stroke, Parkinson’s disease, and amyotrophic lateral sclerosis) with management targeted therapy goals or disease progression [ 13 , 14 , 15 , 19 , 20 ]. Personalized TP training is a new focus for improve swallowing.…”

Personalized tongue pressure (TP) training focuses on improving swallowing. This study aims to establish the TP values of different age levels and compare changes between different swallowing status among community-dwelling elders. In this cross-sectional study, 1000 participants, aged 60 years old and above, were recruited from community care centers. All participants were classified into non chewing and/or swallowing difficulties (NCSD) and with chewing and/or swallowing difficulties (CSD) groups and their diseases and dieting status were recorded using a structured questionnaire. A disposable oral probe was used to measure TP by asking participants to compress it against the hard palate with maximum voluntary effort. Among 1000 elders, 63.10% had CSD and their TP (from 31.76 to 18.20 kPa) was lower than the NCSD group (from 33.56 to 24.51 kPa). Both groups showed the same tendency for TP decline with increasing age. Decline of TP makes CSD elderly have a poor appetite, eat a soft or liquid diet, and take longer to eat a meal (all p < 0.050). The secondary risk factor dominating TP decline for NCSD and CSD elders is having an education level less than primary school and an abnormal eating assessment, respectively. Our results demonstrated that TP decline has a significant relationship with age changes. Education level and an abnormal eating assessment score are closely associated with TP decline. A series of TP values can be used as a reference indicator of personalized medicine during the aging process among community-dwelling older adults.

“…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.…”

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.
