Guiding functional reorganization of motor redundancy using a body-machine interface

摘要

Experimental Setup and Protocol. Panel – participants set in a chair with the sensors strapped around the arms and forearms as depicted, two per side, and were free to move their arms in a comfortable range. A screen positioned in front of the subjects displayed the cursor position, the current target position and a score in the top right corner. Panel – target locations for the reaching task (top panel), and trajectory followed by the moving target during tracking (bottom panel). Panel – summary of the experimental protocol for the Constant map group (top) and Adaptive map group (bottom). H stands for the BoMI map obtained after calibration, which is used by the Constant group throughout the session. H is the map updated iteratively during reaching in the Adaptive map group, and H is the final map after adaptation
