Figure 5: Gait parameter correlations. Scatter plots showing the correlations between gait parameters and body weight ((a), (b)) and locomotor speed ((c), (d)) of the left and right forepaws. Linear regression lines were plotted in each group (solid lines for sham-operated and dotted lines for MCAO rats). The values of Pearson’s Products Moment Correlations Coefficients () and -values are shown for each group. Maximum contact area (a) and toe spread (b) showed positive correlation with body weight. By contrast, the maximum contact area (c) and stance (d) showed negative correlations with locomotor speed. Values for the left and right hindpaws followed the same correlation patterns (data not shown).
