A: The experimental setup. A wooden piece was placed underneath the subject’s right palm in order to avoid changes in the configuration of the hand and fingers. B: The feedback computer screens during the MVC task (left) and accurate total force (FTOT) and total moment of force (MTOT) production tasks (right). During each trial for the accurate FTOT-MTOT production tasks, the screen showed a target and a cursor with coordinates corresponding to the current FTOT along the vertical axis and MTOT along the horizontal axis.
