The measurement items were spontaneous swallowing frequency (SSF), voluntary swallowing frequency (VSF), saliva secretion volume (SSV), glucose elution volume (GEV), and velocity of chew (VOC). All participants underwent both IFCS and sham stimulation (without stimulation, sham). Two sets of independent IFCS electrodes were placed on the bilateral neck. The precise location of the upper electrodes was just below the angle of the mandible, while the lower electrodes were placed at the anterior border of the sternocleidomastoid muscle. The intensity of IFCS was determined to be one level below the perceptual threshold that all participants felt discomfort. Statistical analysis was performed using a two\u2010way repeated measures analysis of variance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For IFCS, the results of each measurement before and during stimulation were SSF: 1.16 and 1.46, VSF: 8.05 and 8.45, SSV: 5.33 and 5.56\u2009g, GEV: 171.75 and 208.60\u2009mg\/dL, and VOC: 87.20 and 95.20, respectively. SSF, GEV, and VOC during stimulation were significantly increased by IFCS (SSF, <jats:italic>p<\/jats:italic>\u2009=\u2009.009; GEV, <jats:italic>p<\/jats:italic>\u2009=\u2009.048; and VOC, <jats:italic>p<\/jats:italic>\u2009=\u2009.007).
