SEP onset latencies (a) and peak-to-peak amplitudes (b) of hindlimb stimulation in the five groups of rabbits at scheduled times. ** indicates significant differences between the 50-μl PRD and 50-μl PCD groups (p < 0.01). $$ and $$$$ indicate significant differences in the onset latency at 3 weeks and 2 weeks after SCI (p < 0.01 and p < 0.0001, respectively). # and #### indicate significant differences in the onset latency and amplitudes at 1 week and 1 day post-compression (p < 0.05 and p < 0.0001, respectively). D: Day. W: Week. 1st dec: first decompression, 2nd dec: second decompression
