Learning an EMG Controlled Game: Task-Specific Adaptations and Transfer
Fig 6
Representative example of the hand aperture during the pretest (left figure) and posttest (right figure) during grasping a medium size cylinder. Both examples are from the same participant. This participant was assigned to the Breakout-EMG group, however the example is equally representative for the Control group. The time (s) is shown on the x-axis, the normalized aperture on the y-axis. A change in aperture of 0.1 corresponds to a change of ~1 cm in distance between thumb and index finger. The lines represent five trials of grasping a (medium) cylinder. The four round markers on each line represent (from left to right) the start of the opening, the end of the opening, the start of the closing and the end of the closing of the hand.
