Therefore, the objective of this study was to compare the variables of angular kinematics of the wrist joint in typing activities with and without the use of an inclination rod for the keyboard. This study is characterized as a descriptive one of the type case study. Materials and Methods: The sample was composed of one female individual aged 23 years old. For the data collect, a DSC-P32 60 Hertz Sony ® digital camera and DGEEME ® software, version 0.98b were used. To compare the kinematic characteristics of two situations (with or without inclination rods for the keyboard) was used the Wilcoxon non-parametric test, p<0.05. Results: The results showed that on the keyboard with rods the maximum wrist fl exion was 5.55° and the maximum extension was 27.87°, while on the keyboard without rods was 13.72°, and 19.38° of fl exion and extension, respectively. There was a significant difference between typing on the keyboard with and without rods (p<0.01). It was found that the wrist remained 71.8% and 52.2% of the time in positions rated as very good and characterized as neutral on the keyboard with and without rods, respectively. Discussion: The conclusion is that the keyboard without inclination rods provides with a more appropriate posture for the wrist, remaining most of the time in a position rated as very good.
