Correlation of cognitive function and kinematic movement during self‐feeding activity

Abstract

AbstractBackgroundSelf‐feeding is the important activity that is most closely related to daily living using motor and cognitive abilities. Especially, movement of self‐feeding includes picking up the spoon and executing the sequence of movement correctly, so it can be related to cognitive aspects. The purpose of this study is to investigate correlation with the kinematic movement during self‐feeding and cognitive function using AI software programMethodThe subjects participated in 4 normal person. In this study, the ‘simulated feeding’ task in Jebsen Taylor Hand Function test was selected. ‘Simulated Feeding’ is a task of transferring 5 beans to cup with a spoon. During task performance, a laptop and a webcam were used to record a video image, and trajectory and time value were recorded from 2D web‐cam image. Cognitive assessment tool used Trail Making Test (TMT). The spearman correlation analysis was conducted to evaluate the correlation with factors of movement and cognition during self‐feeding.ResultIt is possible to determine how far or short the hand moved depending on the length of the trajectory. The average time value shows the subject spent more time to put the beans in the spoon than to put the beans in the cup. Also, movement of self feeding were positively related to cognitive aspects..ConclusionWe believe that quantitative assessment of movement is related to cognitive function during self‐feeding. Through this, the state of cognitive function can be indirectly confirmed. Future study will need to apply movement analysis to evaluate the cognitive decline of the elderly.
