Temporal-spatial and kinematic changes in gait with each condition.

	First visit (11 months post-stroke)	Second visit (16 months post-stroke)	Third visit (17 months post-stroke)
	PLS AFO	AFO-FC (SVA 15°)	AFO-FC (SVA 12°)	Shoe only
Stride Length (cm)	45.5	72.8	76.0	47.3
Nondimensional Velocity*	0.09	0.21	0.24	0.07
Cadence (steps/min)	68.8	98.0	104.2	50.1
Step Width (cm)	27.7	23.7	23.7	32.8
Paretic Toe Off Time (%)	77	61	66	85
Paretic Hip Range of Motion (°)	17	16.4	13.4	18.1
Paretic Knee Range of Motion (°)	13.4	19.7	26.1	19.3
Paretic Ankle Range of Motion (°)	15.7	9.2	11.4	16.4

^*The nondimensional velocity normalizes walking velocity by $\sqrt{g\ast L_{\mathit{\text{leg}}}}$. Where g is gravity and L_leg is subject leg length. PLS AFO=posterior leaf spring ankle foot orthosis; AFO-FC= ankle foot orthosis-footwear combination; SVA=shank-to-vertical angle.
