Figure 3. Scatter plots showing the relationships between leg-length inequality and between-leg gait symmetry for sagittal-plane joint angles (A-C), moments (D-F), and powers (G-I). Greater symmetry coefficients (vertical axis) indicate more symmetrical gait. The relationships between leg-length inequality and gait symmetry were all negative, indicating that gait was less symmetrical for subjects with relatively larger leg-length inequality. The asterisks indicate relationships that were statistically significant (α = 0.05).
