Outline of Final Research Achievements

Laryngoptosis or uncoordinated movement of hyoid and larynx in functions in elderly people and dysphagic patients may cause impaired transport of bolus and residues after swallowing, which leads to bolus penetration or aspiration. The present study was undertaken to validate the relationship between hyoid movement or tongue pressure production and swallowing function by evaluating spatial and temporal hyoid excursion, hyoid position and bolus transmission as well as voluntary generation of anterior and posterior tongue pressure in healthy and dysphagic humans.
