Interventions/Control_1
Jaw Opening Exercise group.
The exercise is performed in a sitting position with a stable torso. The subject is asked to open the mouth to the maximum extent possible, and to hold it for 10 seconds while being conscious of the strong contraction of the suprahyoid muscles, and then rest for 10 seconds, repeating the exercise 5 times. With this as 1 set, subjects perform this training 3 times a week for 3 sets a day.
Interventions/Control_2
Lingual Resistance Exercise group.
Using tongue pressure measuring device (JMS tongue pressure measuring device / GC Co., Ltd.). The subject performs a repetitive action of pressing the tongue apex against the hard palate at 100% of maximum tongue pressure, holding for 10 seconds, and resting for 10 seconds, repeating the exercise 5 times. With this as 1 set, subjects perform this training 3 times a week for 3 sets a day.
Interventions/Control_3
Tongue-Hold Swallow Exercise group.
The subject performs an empty swallow by holding the tongue lightly between the upper and lower incisors while the tongue is parroted forward, repeating the exercise 5 times. With this as 1 set, subjects perform this training 3 times a week for 3 sets a day.
