Profile analysis of distal hindlimb muscle activity from intact and injured rats. (A) A scree plot showing the eigenvalues associated with the first five principal components. Eigenvalues for the first two principal components are represented by stars. (B–D) Average loading factor values for PC1 and PC2 illustrated as bubble plots for Us, Ds and Lv walking. Symbol size is proportional to the s.e.m. (i.e. larger bubbles indicate larger variance about the mean). Black, gray and white bubbles represent data from intact rats, rats at 4 weeks post-injury and rats at 10 weeks post-injury, respectively. Dotted lines enclose sets of bubbles that are not significantly different from one another.
