“…This finding is similar to the results of MPT and ODK reported in the present study, and MPT may be closely related to oral function. However, as oral function was not assessed in this study and posture 26 and other factors were not limited, further research is needed.…”

BackgroundMaximum phonation time (MPT) is used to assess speech and other oral rehabilitation‐related issues. Various factors contribute to MPT decline in older individuals. Although the impact of physical frailty on MPT has been suggested, this has not been conclusively determined.ObjectiveTo examine the relationship between MPT and physical frailty in community‐dwelling individuals aged ≥60 years who were independently mobile. MPT‐associated factors were investigated.MethodsThis cross‐sectional study analysed the clinical data of 122 patients (age [interquartile range]: 80.0 [74.0–83.0] years) without dementia who visited a neurology department between 1 February 2021 and 31 January 2023. Investigated factors included age, sex, weight, height, body mass index, smoking history, grip strength, functional independence measure, vital capacity, oral diadochokinesis, MPT and the Japanese Cardiovascular Health Study score. Physical frailty was assessed based on the total score from five items (weight loss, weakness, exhaustion, slowness and low physical activity). The relationship between MPT and physical frailty was examined using Spearman's rank correlation coefficient and hierarchical multiple regression analysis.ResultsThe MPT was negatively correlated with age (r = −0.347, p < .01) and physical frailty (r = −0.681, p < .01) and positively correlated with vital capacity (r = 0.474, p < .01) and height (r = 0.248, p < .01). The hierarchical multiple regression analysis, conducted with MPT as the dependent variable, demonstrated that physical frailty (β = −.59, 95% confidence interval: −0.74 to 0.43, p < .001) had a strong influence on MPT.ConclusionIn older individuals, MPT is associated with physical frailty. When assessing MPT in clinical settings, it is advisable to perform a concurrent assessment of physical frailty.

“…Correcting the FHP was not addressed in the OMT, but occurred somehow “naturally” and in a very low percentage; the change was dramatic and obvious in group A (from a mean of 42.4 to 49.05, a normal angle), as well as in all the outcome variables, proving that the MT and GPR helped in the rehabilitation of the swallowing. These changes may involve the suboccipital muscles, as they act to maintain the posture of the head, in synergy with global chains and in relation to input from the visual, mandibular and swallowing systems [ 7 , 8 , 63 , 64 ].…”

“…Long axis traction / distraction of C0-C2; FHP, with posterior cranial rotation and stretching of the infrahyoid muscles, leads to an increased activity of the masticatory muscles and cranial extensors [7][8][9][10]. The muscles of mastication will try to maintain the mandible up (mouth closed, lips touching) and the infrahyoid muscles are trying to bring the mandible down and back; the result is a continuous fight between the mandible depressing and elevating muscles.…”

(1) Background and Objectives: The forward head posture (FHP) is characterized by increased extensions of upper cervical vertebrae and flexion of the lower cervical vertebrae and upper thoracic regions, associated with muscle shortening. The compressive loading on the tissues in the cervical spine negatively impacts suprahyoid and infrahyoid muscles and generates increased tension of the masticatory muscles. The tongue has relations with the suprahyoid and the infrahyoid muscles. The pattern of swallowing evolves gradually from birth to the age of four. If this developmental transition does not occur, the result is persistent infantile or atypical swallowing—an orofacial myofunctional disorder with the tongue in improper position during swallowing, causing strain and stress on the jaw, face, head and neck. In FHP, muscles crucial to swallowing are biomechanically misaligned. The lengthening of the suprahyoid muscles necessitates stronger contractions to achieve proper hyolaryngeal movement during swallowing. This study assesses the added benefits of physiotherapy to the traditional myofunctional swallowing rehabilitation for patients with FHP. The underlying hypothesis is that without addressing FHP, swallowing rehabilitation remains challenged and potentially incomplete. (2) Materials and Methods: A total of 61 participants (12–26 years) meeting the inclusion criteria (FHP and atypical swallowing) were divided into two similar groups. Group A attended one orofacial myofunctional therapy (OMT) and one physiotherapy session per week, group B only one OMT session per week, for 20 weeks. Exclusion criteria were as follows: ankyloglossia, neurological impairment affecting tongue and swallowing, cervical osteoarticular pathology, other previous or ongoing treatments for FHP and atypical swallowing. (3) Results: There is a significant improvement in terms of movement and use of the orofacial structures (tongue, lips, cheeks), as well as in breathing and swallowing in both groups. Group A achieved better outcomes as the CVA angle was directly addressed by manual therapy and GPR techniques. (4) Conclusions: The combined therapy proved to be more effective than single OMT therapy.

“…The kyphosis posture is a common postural change associated with aging, but studies examining the relationship between this structural change and swallowing function have received little attention. Although swallowing function in response to postural changes has been studied 2 ) , comprehensive studies examining respiratory and swallowing functions have not been conducted. Studies on respiratory function have shown that unlike the muscles of the extremities, trunk muscles (e.g., intercostal muscles) and diaphragm atrophy of both white and red muscles as a function of age 3 ) .…”

[Purpose] To evaluate the effects of kyphosis on swallowing and respiratory functions. [Participants and Methods] In 94 healthy adult volunteers, the respiratory (vital capacity, percentage of vital capacity, and cough peak flow and swallowing (hyoid amplitude and tongue pressure) functions, were evaluated under the following conditions: vertical, moderate kyphosis, and severe kyphosis postures defined by the round-back index. [Results] The mean vital capacity and percentage of vital capacity were significantly lower in severe kyphosis than in the vertical posture. The suprahyoid muscle amplitudes, tongue pressure, and cough peak flow was significantly lower in severe kyphosis than in moderate kyphosis or the vertical positions. [Conclusion] The swallowing and breathing functions were significantly lower in volunteers with severe kyphosis than in those with moderate kyphosis or the vertical positions. Although strengthening of the suprahyoid muscles is a typical example of rehabilitation for dysphagia, but it may also be necessary to consider postural adjustment for patients with kyphosis. A comprehensive evaluation of swallowing function that takes both posture and respiratory function into consideration is necessary.
