Fig. 2 — Effects of external forces on EMG. The figure, from left to right respectively, reports the kinematics (first 3 graphs from the top) and the dynamics (last 3 graphs) of the upper limb when different type of loads are applied: inertial, viscous and elastic forces. Red arrows underline the main variations in burst intensity: antagonist bursts increase for inertial loads, decreases with viscous loads, and decreases slightly with elastic loads (adapted from Gottlieb [67])
