Background: Early training in myosignal control interface is important for functionality with myoelectric hand prostheses. Learning new motor skills requires the formation of an action system. Forming an action system requires a goal, which a game can provide in early rehabilitation. Aim: To study whether an action system that incorporates myoelectric control can be learned by game training, and whether this motor skill transfers to prosthetic control. It was hypothesized that the game group improved more on the game and prosthesis task than the control group. Methods: 27 able-bodied right-handed participants were randomly assigned to a training group; game (n =15) or control (n=12) and trained 20 minutes per day during four days. The game group trained the Breakout game with myoelectric control; the control group played a regular game without myoelectric interface. A game and prosthesis (myoelectric prosthesis simulator) task were tested before and after training. Repeated measures were performed, with within factor time and between-factor group. Dependent variables for game were: accuracy, duration of play, flexor- and extensor EMG and the coupling between game and average EMG signal (game EMG). For prosthesis task: the plateau phase duration and relative hand opening. The level of significance of all tests was set at p < 0.05. Results: An interaction effect of time x group were found for accuracy (F1,25 = 24.19, p < .01), and game EMG (F1,25 = 4.75, p <.05). The game group improved more on these variables than the control group. No interaction effect of time x group was found for flexor EMG and duration of play. For the prosthesis task no interaction effects were found for either variable. Conclusion: Specifics in the game showed that an action system that incorporates myoelectric control was formed by game training. However, this action system did not transfer to prosthetic control in a prosthesis task. To enhance the possibility of transfer, augmented feedback about the prosthesis task’s goal could be applied into the game. Keywords: Action system, game training, prosthetic control, transfer
