Oropharyngeal swallowing in normal adults of different ages

Stagetransition duration is closely related to delayed triggering of the swallow reflex, a characteristic commonly reported in dysphagic populations7~27-2g and frequently associated with aspiration.4*30 our findings indicate that the increase in stage-transition duration alone, even within the range of values seen in the older individuals in our study, does not lead to aspiration

  • Penetration occurred in the following number by age group and condition as follows: group I, 7; 6cm above upper esophageal sphincter [A ItC+ I
  • A major finding of this study is that as people get older, they swallow more slowly. This change occurs in the presence of unchanged amplitude of pharyngeal pressures with age
  • Other authors have speculated on the association between age-related changes in swallowing and the limited ability of the swallowing mechanism to successfully compensate for changes in muscle tissue, sensory function, and other anatomic and physiological characteristics.‘0*‘8’26 The specific underlying mechanisms currently remain unclear
  • The present study suggests that pharyngeal pressure and propagation are preserved in normal aging
  • The major findings of this study showing slowing of oropharyngeal swallowing in the presence of unchanged pharyngeal or UES pressure parameters in normal aging may be used in the diagnosis of dysphagia
