Introduction
human motor behavior, Handedness
Handedness is a prominent feature of human motor behavior. Indeed, most humans have a natural tendency for using one arm, i.e., the dominant arm, when performing a wide range of movement tasks. Studies have revealed an advantage of the dominant arm in the control of limb dynamics (Although attractive, this hypothesis implies that participants can modulate the mechanical impedance of their limb to modify their behavior, presumably through the combined activation of agonist-antagonist pairs of muscles acting on each joint (Regarding the role of feedback, recent studies reported very small changes in background EMG activity across limbs in perturbation tasks (However, recent results have shown that the two arms can develop feedforward adaptation equally well (
