Targeted Engagement of the Action Selection Network during Task-Oriented Arm Training after Stroke

Figure 1

Example of training task with action selection cues. (a) Training involved task-oriented training (e.g., functional movement of picking up a marble and placing it into a cup) with the addition of action selection demands to each movement repetition (e.g., visual cues dictated whether the marble should be picked up from the right bowl or the left bowl on each movement repetition). (b) The action selection rule varied (shapes and rules were changed to maintain challenge) and was used to provide selection of movements to the right or left, to a low surface or a high surface (e.g., pick up marble from the low table or the high table), or to a close location or a far location (e.g., pick up a marble from a close bowl or a far bowl).
