Tongue cleaning enhances activity of suprahyoid muscles during exhalation in healthy young adults: A randomized controlled intervention study

A four-week randomized controlled trial was conducted with 30 participants aged 21-22. The participants were divided into two groups: an intervention group that practiced tongue cleaning in addition to routine oral hygiene, and a control group that practiced only routine oral hygiene. sEMG was used to assess the myoelectric activity of the suprahyoid muscles during various actions, including inhalation, exhalation, head lifting, tongue pressure, and tongue cleaning. The sEMG data were presented as microvolt root mean squares (RMS). An examination was conducted at baseline and after the 4-week intervention period. The study is registered in the “Effect of oral care on improving coughing ability to prevent aspiration pneumonitis” trial registry under the registration number UMIN000026327.A four-week randomized controlled trial was conducted with 30 participants aged 21-22.
