Outcomes of Electrophysiology, BBB Locomotion Assessment, and Grid Climb Test(A) CMEPs were obtained by electrophysiological analysis in the GS, GS + EA, NN, and NN + EA groups.(B and C) Bar charts showing the (B) latency and (C) amplitude of CMEPs (n = 5/group; one-way ANOVA with LSD t).(D) Graph of BBB score of the hindlimb locomotor function in 5 groups (n = 10/group; one-way ANOVA with LSD t).(E) Bar charts showing the percentage of rats that recovered two sensorimotor reflexes with one hindlimb or two hindlimbs in 45 inclined grid climb test (n = 10/group; Fisher’s exact test).(F) Serial pictures of movement of the rats’ feet (arrowheads) while crawling upward from bottom. *p < 0.05 indicates significant difference from the GS group; #p < 0.05 indicates significant difference from the GS + EA group; &p < 0.05 indicates significant difference from the NN group; $p < 0.05 indicates significant difference from the NN + EA group.
