In order to examine the relationship between nutritional status and oral function training using tongue pressure, we conducted tongue training for 8-weeks using the “Peko Panda^®” oral function training equipment for elderly residents of a nursing care facility for the elderly. Tongue pressure was measured thrice before commencement of tongue training, 8 weeks after commencement, and 1 month after training completion. We divided the data before and after the intervention period into the implementation 2 groups; those who were able to perform three times a week as prescribed (the implementation group), and those who could perform less than the prescribed number of times and those who withdrew from the course (the withdrawal group). Tongue pressure in the implementation group was significantly higher after 8 weeks than before training commencement; however, no significant difference was observed in the withdrawal group. The nutritional status of Mini Nutritional Assessment-Short Form (MNA^®-SF) increased before and after the intervention in both the implementation group and the withdrawal group, but there was no change in body weight, and anthropometry, so it cannot be said that nutritional has improved. However, there is a possibility that the tongue pressure value will increase by continuing tongue training during admission, indicating the usefulness of tongue training.
