Linear regression model for walking velocity and VO₂ peak.

	Sp_12m			VO2 peak
	Beta coefficient	value	^2	Beta coefficient	value	^2
90DT_PL	0.621	0.004	0.497		0.614	0.422
90DT_NPL		0.488		0.559	0.011
FIM	0.153	0.280		0.107	0.707
Sp_12m	—	—		0.242	0.214
VO2 peak	0.211	0.214		—	—

Sp_12m: speed of total 12 meters; VO₂ peak: peak O₂ consumption; 60DT_PL: 90-degree torque of paretic leg; 90DT_NPL: 90-degree torque of nonparetic leg, FIM: functional independent measurement.
