 Pencil grip forms and movement patterns of the fingers, wrists and forearms among left-handed subjects were analyzed in order to describe the characteristics of left-handed handwriting. These characteristics were compared to those of right-handed subjects. Fourteen healthy left-handed subjects as well as 14 right-handed subjects participated in the study. The mean age of the subjects was 20.0. The each subject was observed while tracing a “+” and a “×” 1cm and 2cm in diameter with a pencil. The observation was described based on a pencil grip classification by Otaki et al. and a finger movement classification by Kamakura.

 The movement of the wrist and finger joints was antagonistic between left- and right-handed groups during horizontal line drawing. On the other hand, the movement of these joints was closely matched between the two groups during vertical line drawing. During the diagonal line drawing, the joint movement between the two groups lacked similarities. The thumb in the left-handed group moved in a more complicated manner, compared to the right-handed group. The findings in this study could be guidance for OT intervention in switching hand-dominance.
