Spearman’s rank-order correlation coefficients of gait function and age, period from the onset, number of training sessions, function of lower extermity and postural control before HAL training, respectively

Variables	Subacute phases	Chronic phases
Age	−0.19	−0.18
Period from the onset	−0.14	0.24
Number of training sessions	0.06	−0.28

Balance score of FMA before training	0.24	0.78***

FMA: Fugl-Meyer assessment, HAL: hybrid-assistive limb,
