Multidimensional scaling of the pairwise distances of all tested movements. Results are for the same participants shown in Fig. 2 (separated by column), ages 8, 10, and 20, respectively. We used multi-dimensional scaling to visualize the trajectories of each missing limb movement in three dimensions. We observe that while movements often follow similar curvatures, they remain spatially separate. Furthermore, they do not align sequentially along a single curved path. The relative positions of each missing hand movement in this low dimensional space are highly subject dependent
