Sponsor's own description

Swallowing; It is a complex, dynamic, sensorimotor process involving more than 30 muscles located bilaterally in the oral, pharyngeal, and esophageal regions and involving the safe delivery of the food taken from the mouth to the stomach as a result of sequential and coordinated movements. The cervical region is important in terms of swallowing function, as it acts as a bridge between the oral and esophageal structures through the pharynx, hosts the larynx and upper respiratory tract, which plays an important role in safe swallowing, and contributes to the stabilization and preservation of posture thanks to the muscles in its structure. Craniocervical flexion (CCF) occurs at the atlantooccipital joint and upper cervical segments such as C1-2. While superficial muscles such as the SCM and anterior scalene muscles contract in cervical flexion, deep muscles such as the longus colli and capitis, which are mainly primary cervical stabilizer muscles, are activated in CCF. CCF is a movement felt as flexion in the upper part of the cervical region with a slight retraction of the chin. It is also known that the suprahyoid muscles are activated in CCF. Swallowing in the CCF posture has been shown to occur with less suprahyoid muscle activation. The cervical region must provide proper alignment, posture, and stabilization for effective and safe swallowing. Postural changes in the cervical region, and changes in the position of the hyoid bone cause changes in gravity, oropharyngeal structures, and muscle length-tension relationship, thereby changing the dynamics of swallowing function. Therefore, it is not possible to consider the cervical region separately from the swallowing function. However, the focus of the exercises to be chosen for the cervical region is different and the effects that are likely to occur may also be different. There is no study in the literature on the activation of superficial and deep muscles activated during swallowing of craniocervical flexion training exercises, which aim to improve cervical region mechanics by focusing especially on deep cervical flexors. The aim of this study is to investigate the effect of craniocervical flexion training (CCF) on swallowing-related structures in healthy individuals.
