Moreover, during swallowing, the neck muscles help to stabilize the cranium on the thorax, counterbalancing the propulsive forces exerted by the tongue, pharynx, and lar-ynx [5]. In dental research and in orthodontics it has been accepted for long time that saliva swallowing could be divided into two groups: Typical and Atypical swallowing.

The change of neck electrical impedance in pharyngeal phase is mainly caused by the changes of equivalent cross sectional area of near epiglottis.

Adequate swallowing, an innate and complex function responsible for directing the bolus from the mouth to the stomach, involves the synergistic participation of many head and neck muscle groups(1,2). The jaw elevator muscles, which include the masseter muscle, have an important role in the physiology of swallowing, especially regarding the function

Based on these differences in impedance characteristics, liquid, gas, and mixed liquid gas events can be differentiated. When multiple impedance electrode pairs are mounted on to the same catheter, the direction and extent of bolus movement can be measured.
