Table 3. Means (±standard deviations) for degree of gait symmetry, quantified via the symmetry coefficient, for two groups of able-bodied subjects: (1) leg-length inequality less than 1 cm (n = 19), and (2) leg-length inequality equal to or greater than 1 cm (n = 7). Lower symmetry coefficients indicate less gait symmetry. The degree of gait symmetry was significantly less for sagittal-plane knee and ankle joint moment and power for subjects with a leg-length inequality that was greater than or equal to 1 cm.
