The effortful swallow, a compensatory technique frequently employed by speech-language pathologists for their patients with dysphagia, is still not fully understood in terms of how it modifies the swallow. In particular, although age-related changes are known to reduce maximum isometric tongue-pressure, it is not known whether age affects people’s ability to perform the effortful swallow. In this study, differences were explored between younger and older healthy women in execution of the effortful swallowing maneuver through a comparative analysis of effortful and non-effortful swallows.
Eighty healthy women (40 aged 18-35 years; 40 aged 60 years and older) participated.
Peak amplitude measures and the timing of signal onset to peak were measured using concurrent tongue-pressure and submental surface electromyography.
Statistically significant main effects of age-group were not observed in the amplitude data, but older participants showed slower rise-times to peak anterior tongue-palate pressure.
Despite the general age-related deterioration of the swallowing musculature due to the phenomenon of sarcopenia, older women can still produce non-effortful and effortful swallows with similar lingual pressure and submental EMG amplitudes to younger women.|
