Trajectory of the hand for the Drinking task in a, b, c and Pouring in d, e and f. The angular wrist movement in state-space of ulnar-radial deviation ϑ over flexion-extension φ in a, d and pronation-supination over flexion-extension φ in b, e. In c and f the trajectory of the hand in space is plotted in the relevant plane XZ and YZ respectively
