Kinematics, kinetics, and energetics of the lower limb pointing task. Segment angles, joint power, joint torque, and parsed joint interaction torques for the controls (ensemble average, n = 12) when pointing to the (A) HKA, (B) KA, and (C) HA targets in the full vision condition. Shaded areas around each trace represent the 95% confidence intervals. Data are presented for the duration of the reversal phase and vertical bars represent the reversal point (see Fig. 2A). For the power traces, positive values represent generative and negative values represent absorptive power. Flexor/dorsiflexor torques are positive. The inset stick figure in the top left corner indicates the orientation of segment angles (see also Fig. 2C)
