Therapeutic interventions often prioritize swallowing maneuvers as preferred options. Nevertheless, the current body of literature indicates that the application of ultrasound in the assessment and treatment of swallowing disorders remains limited, with a scarcity of studies investigating muscle activation and laryngeal elevation during these swallowing maneuvers. This research seeks to compare the movements and timing of the floor of the mouth muscles across various age and gender demographics, while also aiming to procure quantitative data on hyoid-laryngeal convergence during the maneuvers, thereby substantiating the implementation of US in conjunction with three commonly employed swallowing maneuvers for the intervention of disorders affiliated with the oropharyngeal phase of swallowing. The results indicate that the duration of swallowing maneuvers tends to increase with advancing age, with the Mendelsohn maneuver emerging as the most efficacious technique for hyoid-larynx convergence. Conversely, it was also observed that the Mendelsohn maneuver posed the greatest challenge for subjects in terms of cooperation. Consequently, this study demonstrates that ultrasound can be effectively utilized during the execution of swallowing maneuvers, while also providing valuable insights into muscle activation associated with these interventions.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144689576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to determine prevalence and predictors of self-reported swallowing difficulty in community-dwelling older adults. The National Health and Aging Trends Study is a nationally representative population study that has followed American Medicare beneficiaries aged 65 and older since 2011. Annual, interviews collect detailed information on biological, medical, psychological, social, lifestyle and economic data. The current study analyzed data from the first 11 rounds of interviews to estimate prevalence and the predictors of self-reported swallowing difficulty. Estimates of prevalence were computed per year based on analytic weights and linearized standard errors. Logistic regression was used to determine the predictors of participant-reported swallowing difficulties for a subgroup of adults in Round 5, as well as 1497 community-dwelling older adults who responded to all 11 rounds of interviews, representing a stable cohort across 11 years. For both models, lifestyle and health factors were considered, such as: smoking; requiring help to eat and prepare meals; life satisfaction; social participation; various medical conditions; cognition; fall status; and respiratory status. Prevalence of self-reported swallowing difficulty ranged from 8.7 to 10.2% over 11 years, with many participants experiencing swallowing difficulties intermittently. Cross-sectional analyses (Round 5 data) revealed that the odds of swallowing difficulties increased with less education, those identifying as Hispanic as compared to white, and those with relatively lower incomes. Longitudinal analyses, controlling for the effect of age, suggested the following independent predictors over time: self-reported poor health, higher BMI, reduced peak airflow, needing help to eat, and limited physical activity. This information should be carefully considered by clinicians, researchers, and policymakers to ensure we are able to address the needs of our dysphagia patients as they continue to age. Social determinants of health must also be considered to ensure equitable care across the population.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144658728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed a retrospective analysis of 288 swallows from 135 healthy Japanese adults (median age, 43 years; height, 163 cm) who underwent Swallowing CT. Test boluses included thin or extremely thick liquids in either 3 mL, 10 mL, or 20 mL amounts. Pharyngeal cavity volume at bolus hold (PVHOLD), unobliterated air and bolus volume at maximum pharyngeal constriction (PVMAX), and pharyngeal volume constriction ratio (PVCR), and post-swallow pharyngeal residue were measured on dynamic 3D-CT images using a semi-automated software. We determined the 2.5th, 50th, 97.5th percentile values to obtain normative reference values for each parameter and made generalized linear regression models to determine how these volume measurements are associated with demographic factors and bolus properties. Normative values (median [97.5th percentile]) across all swallows were PVHOLD 20.9 cm³ [38.6 cm³], PVMAX 0.3 cm³ [2.1 cm³], PVCR 98.8% [2.5th percentile 89.1%], and residue 0 cm³ [0.4 cm³]. Males exhibited larger values than females. PVHOLD significantly increased with height (β = 0.465, p < 0.001) and age (β = 0.068, p = 0.001), while PVMAX and PVCR increased with larger bolus volumes (β = 0.293, p = 0.005) and in thicker consistencies (β = 0.376, p = 0.017). Pharyngeal residue was present in 98/288 (34.0%) of swallows and was significantly associated with increasing bolus volume (adjusted odds ratio [aOR] = 1.865 [95% confidence interval: 1.275-2.727]), age (aOR = 1.025 [1.010-1.040]), thicker bolus (aOR = 1.806 [1.275-2.727]).

Its effectiveness presumably relies on proper execution. This study assessed the effect of different instructional strategies on neck muscle activation in older adults executing a sustained CTAR contraction. Ninety healthy individuals aged 65 to 90 years old were randomly assigned to one of three groups: video-only, video plus verbal instruction, or video with visual biofeedback using surface electromyography (sEMG). Surrogate measures of muscle recruitment and fatigue within both the suprahyoid and sternocleidomastoid muscles were compared across the three instructional groups. The sEMG amplitude measures were normalized with respect to maximal jaw opening and head rotation. Suprahyoid activity was significantly higher than sternocleidomastoid in terms of both normalized amplitude and fatigue. An analysis of variance failed to show significant differences in either sEMG measures as a function of instructional strategy, although the distribution of responses with biofeedback was significantly more clustered around the group mean (i.e. leptokurtic). The effects of sustained CTAR contractions on suprahyoid activity remain consistent across different instructional strategies, suggesting the technique is a robust one. Biofeedback does seem to improve groupwise performance predictability, however.

Eligible studies included randomized controlled trials (RCTs) and quasi-experimental studies assessing treatment measures for dysphagia in dementia patients. Seventeen studies met the inclusion criteria, involving 1,593 participants. The methodological quality was moderate, with substantial baseline control and outcome evaluation, but there were weaknesses in randomization, allocation concealment, and blinding.
