[Purpose] The purpose of this study was to research the difference in wrist flexion of right-handed and left-handed persons during writing. [Subjects] This subjects were 25 persons (left handers 12/ right hander 13) and the study was conducted from 06/01/2011 to 10/31/2011. [Methods] A Motion analysis system (Zebris) was used to determine the degree of wrist flexion of right-handers and left-handers. The during writing data were analyzed using descriptive statistical analysis and the independent sample t-test. We used a statistical significance level of 0.5. [Results] Left-handers wrote with the wrist flexion of 2.92 (±9.42) degrees. Right-handers wrote with wrist extension of 8.42 (±2.80) degrees. The degree of wrist flexion during writing was significantly higher for left-handers than right-handers. [Conclusion] When a left-handed person writes, the degree of wrist flexion is greater than that of a right-handed person. To protect the wrist from excessive flexion and to maintain wrist stability, it is necessary to use an instrument that is designed for left-handed persons.
