Fig. 7. Loading the leg with a mass of 142 mg had no effect on the mean closest point of approach of the tibia to either stimulus site (open triangles). Closest points of approach were determined for each trajectory. Small black square, unloaded condition; red circle, load on the proximal femur; green triangle, load on the distal femur; blue triangle, load on the distal tibia. The large black square indicates the mean starting position. The mean closest points of approach for movements aimed at the posterior stimulus site were, on average, anterior to the target. Those for movements aimed at the anterior stimulus site were, on average, posterior to the target. All values are the mean ± 1 S.D. of data pooled from three animals. Number of trials as in Fig. 6.
