Fig. 2. Loading had little effect on the overall pattern of leg movement. Two example scratches are shown for each experimental situation (solid and broken lines respectively). (Ai–Di) Movements made in response to stimuli at the posterior target site (solid and open triangles are the targets corresponding to the scratches shown using solid and broken lines, respectively). The start positions are indicated by solid and open squares. (Aii–Dii) Movements made in response to stimuli at the anterior target. (Ai,ii) Unloaded condition; (Bi,ii) 142 mg load on the proximal femur (open circle); (Ci,ii) 142 mg load on the distal femur (open circle); (Di,ii) 142 mg load on the distal tibia (open circle).
