NASCIS score for neurological status assessment and improvement rate comparsion

NASCIS score		Preoperation	Final follow up	Neurological improvement rate
Paragplegia	Sensation	78.6 ± 15.2	100.5 ± 8.2	22.2 % ± 14.1 %
	Movement	50.0 ± 0.0	77.5 ± 12.4	52.2 % ± 25.8 %
Paraparesis	Sensation	88.5 ± 4.9	112.0 ± 0.0	26.7 % ± 7.5 %*
	Movement	70.7 ± 3.5	100.0 ± 0.0	59.4 % ± 7.3 %Δ

The neurological improvement rate = (postoperative NASCIS score- preoperative NASCIS score) / preoperative NASCIS score

*P < 0.05 vs. Comparison of sensation improvement rate of between paraplegia and Paraparesis

ΔP < 0.05 vs. Comparison of movement improvement rate between paraplegia and Paraparesis
