Arm matching experiment setup. a Schematic representation for arm-matching experiment and b detailed experimental procedure of the arm-matching experiment. Right arm elbow angle is maintained at a specified reference angle with help of armrests and subjects use their left arm to match the left elbow angle to the perceived right arm angle, with or without electrical stimulation applied. Gyroscopes were strapped onto both the arms, to measure the elbow joint angles
