Tibial nerve stimulation (TNS) inhibited the bladder overactivity induced by acetic acid (AA) irritation. A: representative cystometrogram (CMG) tracings with/without TNS during AA infusion into the bladder. Black bars under the pressure trace indicate TNS duration. TNS: 5 Hz, 0.2 ms, T = 3 V. Infusion rate = 2 ml/min. B: normalized bladder capacities measured during CMGs with/without TNS (n = 10 cats). The capacity was normalized to the AA control CMG. *Significantly (P < 0.05, Bonferroni comparisons) different from the control (one-way ANOVA). C: nonnnormalized bladder capacities for every animal.
