H-reflex excitability. At the 12th week post-injury, H-reflex responses at 10 Hz-train stimulation were markedly reduced by subsequent stimuli (normalized to 1st response) in the SHAM and SVF groups. This depression was absent in rats from NaCl group. For a given response, significant difference in the Hmax/Mmax ratio is indicated by a * (NaCl group vs. SHAM group) and δ (SVF group vs. NaCl group) (1 symbol, p < 0.05, 2 symbols, p < 0.01 and 3 symbols, p < 0.001)
