Noninvasive Evaluation of Nerve Conduction in Small Diameter Fibers in the Rat

Figure 5

Changes in distal slow conduction under condition of HFRS: ((a) and (b)) total magnitude of C-fiber compound response (mean, SD, 𝑁=8) during (a) and after HFRS ((b), 0 min—solid line, 5 min—dashed line); (c) and (d) demonstrate changes in representative traces of C-fiber compound response ((c), MUA) and in Aβ-Aδ evoked potential (d) under conditions of HFRS. “S” next to the timescale marks start of stimulation. Asterisks denote statistically significant difference (**𝑃<0.01, *𝑃<0.05) between the magnitude of the initial response to frequency 0.75 Hz and responses during and after HFRS.
