Three hundred and ninety-seven normal adult subjects were tested in order to investigate the prevalences of various patterns of chopstick-use. Manipulation speed was also compared. According to the movement of the fingers, finger positions and contact areas, we can divide the various chopstick-use patterns into 3 basic patterns with 13 variations. Prevalences of the 3 basic patterns were palmar prehension (68.5%), lateral prehension (14.2%), and dynamic palmar prehension (17.3%). There was a statistically siginificant difference in manipulation speed among the 3 basic patterns. The influence of sex and age on manipulation speed was also analyzed for each of the 3 basic chopstick-use patterns. The results of this study will serve as a reference for occupational therapists in the evaluation and training for eating activities.
