Outline of Final Research Achievements

The number of residents in care facilities has increased with the increase in the number of elderly people in Japan. The meal assistance was the most difficult service performed by the care staff. In this study, a swallowing sensor was developed to reduce burden of nursing care staff for meal assistance. The swallowing detection using an accelerometer was easier than detection using EMG methods. We determined a suitable position of the accelerometer to detect a swallowing. The integrated acceleration (iAcc) value at the sternohyoid muscle was significantly larger than that at other positions. We developed a device that equipped an apron with an accelerometer. The device was evaluated, and the iAcc value during swallowing was significantly larger than that during rest in both the young and the elderly people.
