Recently, the translation of neuroscientific theories (i.e. Unfortunately, their complexity often limits mechanical robustness and intuitive prosthesis control. īackground: State-of-the-art bionic hands incorporate hi-tech devices which try to overcome limitations of conventional single grip systems.

To assess the performance of the subjects, four outcome measures as described in were used: acquisition rate, path efficiency, completion time and. The six trials were scattered and presented in a different order to each subject. The distance of the targets from the center was set respectively to 50%, 75% and 100% of the total range during three different trials for each algorithm. The targets were placed at 0, π 8, 2π 8. After a target disappeared, another target appeared after 4s of rest. If the target was not acquired during the first 10s, the attempt was regarded as a failure and the red sphere disappeared. After 500 consecutive milliseconds in which the two spheres overlapped, the target was considered acquired and the red sphere disappeared.

The subjects were asked to reach a fixed target, represented by a red sphere, as quickly as possible, and to keep the blue sphere on the target until disappearance. The control signals extracted by the EMGs were used to control the position of a cursor (a blue sphere) on the screen (see Fig.
