 In this study, we examined the effects of tongue-palate contact training using a hanging scale on the tongue motor function in 30 young healthy adults. Stratified randomization was conducted according to gender and the subjects were divided into the training group (intervention group) and the non-training group (control group). In the training, the subject held a gauze fixed to a hanging scale by the contact force of the tongue and palate, and the trainer pulled the scale in a direction of 30 degrees downward from the horizontal plane. The training intensity was set at 80% of the maximal holding power for 5 seconds. Training was performed 5 times per set, 2 sets per day, and 3 days per week for 7 weeks. The maximal holding power, the maximal tongue pressure, the tongue pressure during effortful swallowing, and the frequency of syllable repetitions for five seconds were compared before and after the intervention period. In the control group, there was no significant change in any of the parameters, whereas in the intervention group, the gains found after training were as follows:2.44kg (+72%) for maximal holding power, 8.3kPa (+22%) for maximal tongue pressure, and for tongue pressure during effortful swallowing 9.4kPa (+29%) in Ch.1, 8.6kPa (+30%) in Ch.2, 12.7kPa (+52%) in Ch.4 and 10.0kPa (+36%) in Ch.5 (p<0.05). The results of the present study suggest that this training might be an effective method of strength training for the tongue motor function.
