Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The participants are instructed to masticate a gum for 20 minutes every day, alternately for 10 minutes on the right side and 10 minutes on the left side.
After chewing gum, they perform masticatory muscle stretching and tongue exercises. After they finish chewing the gum, he or she reports completion by posting an authentication photo in the KakaoTalk chat room.
