Effects of saphenous nerve stimulation (SNS) on bladder capacity (A), contraction amplitude (B), and contraction duration (C) during poststimulation inhibition induced by tibial nerve stimulation (TNS). SNSi-c, SNS applied intermittently during storage phase but applied continuously once a micturition contraction occurred; SNSc, SNS applied continuously from the beginning of the CMG; T, threshold intensity to induce observable muscle twitch on the back of the thigh. SNS: 1 Hz, 0.2 ms, 2–4T = 7–10 V. TNS: 5 Hz, 0.2 ms, 4–8T = 1.6–4 V, 30 min applied for 1–8 times. *Significantly (P < 0.05) different (one-way ANOVA); n = 6 cats.
