Abstract/OtherAbstract:
PURPOSE: To compare the effects of the tongue-hold swallowing maneuver on pharyngeal pressure generation in healthy young and elderly research volunteers. METHOD: Sixty-eight healthy research volunteers (young N = 34: mean age: 26.8 years, SD 5.5; elderly N = 34: mean age: 72.6 years, SD 4.8; sex equally represented) performed five non-effortful saliva swallows and five tongue-hold swallows each. Amplitude and duration of pharyngeal pressure were investigated during both swallowing conditions with solid-state pharyngeal manometry at the level of the oropharynx, hypopharynx and upper esophageal sphincter (UES). RESULTS: At both pharyngeal levels, tongue-hold swallows produced lower peak pressure compared to saliva swallows. During tongue-hold swallows, UES relaxation pressure was increased in the elders, whereas the younger group displayed a trend toward reduced relaxation pressure. Elderly individuals produced pressure for longer during control swallows in the oropharynx and hypopharynx than young individuals. CONCLUSIONS: The tongue-hold maneuver affects oropharyngeal and hypopharyngeal pressure in the young and elders in similar ways, whereas effects on UES peak relaxation pressure differ between age-groups. Reduced pharyngeal peak pressure and increased UES relaxation pressure underscore the notion that tongue-hold swallows should not be performed when bolus is present. Long-term training effects remain to be investigated.
