Table 4.

Mean values, standard deviation, and significant differences of the symmetry index for the peak vertical force and vertical impulse between normal walking and heelwork walking.

	Symmetry PFz (%)			Symmetry IFz (%)
	Mean ±SD		p -value	Mean ±SD		p -value
	Normal walk	Heelwork walk		Normal walk	Heelwork walk
Forelimbs	1.15 ± 0.84	3.56 ± 2.40	0.012*	1.25 ± 0.61	3.62 ± 2.89	0.030*
Hindlimbs	1.58 ± 0.99	3.01 ± 2.43	0.110	1.62 ± 0.81	3.61 ± 2.36	0.028*

Mean ± SD, mean and standard deviation; PFz%, peak vertical force as a percentage of total force; IFz%, vertical impulse as a percentage of total force. Significant differences within the groups are marked with ^*.
