Abstract: This pretest-posttest pilot study was to examine the effects of how olfactory stimulation (OS) influenced swallowingfunction in older adults. Forty-four community-dwelling older residents (24 OS & 20 control) from southern Taiwanwere recruited. Participants in the intervention group administered pre-meal OS using odor and flavor inhalation.The study found that physiological responses for different food textures significantly differed between groups atpost-test (p=.02). Within the experimental group, swallowing function, and individual satisfaction showed significantdifferences before and after the odor inhalation over time (p<.01, ? p 2 =0.16–0.33). An individual’s satisfaction totheir own swallowing capacity was largely enhanced by the significant interaction between time and group (F[1,42]=11.34, p=.002, ? p 2 =0.21), but not for physiological response to OS and swallowing function. The resultssuggest OS may be advantageous to improving physiological response to OS, swallowing function and satisfactionwith swallowing capacity in older adults.
