Experimental conditions. Upper panel) The participant’s starting position and final position for pronation, supination, adduction and abduction experimental conditions. Lower panel) Representation of the inertial device as a rigid inverted pendulum rotating around the long axis of the forearm, for pronation/supination movements (primary plane: frontal), and along an axis perpendicular to the long axis of the forearm, for adduction/abduction movements (primary plane: sagittal). For illustration purposes, the planes are rotated.
