Differences in sensory input and degree of cortical involvement between swallow types may contribute to differences in swallowing physiology. Pharyngeal high-resolution manometry provides an opportunity to characterize both swallow types. Pressure generation and timing events during cued volitional (2 cc thin liquid) and non-cued saliva swallowing were evaluated in 50 healthy adults (n = 25 per sex). Paired t-tests revealed that on average, significantly greater pressures were generated during volitional swallows than non-cued saliva swallows in the velopharynx (p < 0.0001), tongue base (p = 0.045), and UES (post-closure) regions (p = 0.0058), while no significant differences were noted in the hypopharynx (p > 0.05). Positive linear relationships between swallow types were identified for velopharyngeal and tongue base pressures. Additionally, volitional swallows demonstrated longer UES relaxation durations than non-cued saliva swallows (p = 0.0003). While C2-C4 size differed between males (larger) and females (p < 0.0001), sex was not associated with any swallowing outcome measures. Overall, healthy adults generated higher pressures during volitional than non-cued saliva swallows in most pharyngeal regions, whereas the hypopharynx appeared less influenced by swallow type. Positive relationships between swallow types suggest that volitional assessments can serve as useful proxies for spontaneous function and may provide clinically relevant information when standard bolus swallows are difficult to obtain. The absence of sex effects supports uniform interpretation of manometric results across adults. These results underscore the importance of considering swallow type when evaluating swallowing physiology and designing clinical interventions.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13502161/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148600445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to investigate the effect of FHP on submental muscle activation (SMA), dysphagia limit (DL), and anterior and posterior tongue pressure force in healthy volunteers. Fifty-four healthy volunteers were included in the study. All volunteers were photographed from the lateral plane during the water swallowing task for head and neck biomechanics evaluations. The images were analyzed in the ImageJ and the craniovertebral angle (CVA) and cranial rotation angle (CRA) were measured. The volunteers were divided into two groups: Presence of FHP and normal head posture (NHP). For SMA, surface electromyography (sEMG) was recorded during 10 mL normal and 10 mL effortful swallows. The DL of the volunteers was recorded with the help of sEMG. Tongue strength was recorded with the Iowa Oral Pressure Instrument, including anterior and posterior tongue pressure force. There was a significant difference between the SMAs recorded during effortful swallowing between the FHP and NHP groups (p < 0.05). There was no difference between the groups regarding SMA during normal swallow and DL (p > 0.05). There was no difference in anterior and posterior tongue pressure force between the groups (p > 0.05). In the present study, volunteers with FHP had lower SMA during effortful swallow.

The publications to be analysed were identified in January 2026 using the advanced search interface of the Web of Science Core Collection (WoSCC). Following language and document type filtering (English; journal articles), the records were manually reviewed to ensure that oral stimulation was the primary focus of the publications. As a result of the review, 151 documents published between 1983 and 2026 were included in the analysis. VOSviewer was used for keyword co-occurrence networks, thematic clusters, and density visualisations, while the Biblioshiny package was used for descriptive bibliometric indicators.

Concept mapping has shown that the literature maintains a consistent thematic core focusing on preterm infants, oral feeding, and non-nutritive sucking. However, studies in recent years have placed greater emphasis on structured intervention protocols and clinically meaningful feeding outcomes.
