PNS removed the poststimulation inhibition induced by tibial nerve stimulation (TNS). A: repeated CMG tracings showing that 30 min TNS (5 Hz, 0.2 ms, 4T = 1.2 V) produced long-lasting poststimulation inhibition that was completely removed when PNS (1 Hz, 0.2 ms, 1T = 1.4 V) was applied. T, threshold intensity to induce observable toe twitch (TNS) or muscle twitch on the posterior thigh (PNS). The black bar under the bladder pressure tracing indicates the duration of TNS or PNS. Infusion rate = 3 ml/min B: summarized results (n = 5 cats). The bladder capacity was normalized to the control capacity. *Significantly (P < 0.01) different from the control or PNS (1-way ANOVA). TNS (5 Hz, 0.2 ms, 3–4T, T = 0.3–1.2 V), PNS (1–3 Hz, 0.2 ms, 1–4T, 1T = 1.4–12 V).
