Inhibition of bladder overactivity by S1 or S2 dorsal root (DRT) stimulation at motor threshold (T) intensity. (A) Repeated CMGs during saline or 0.5% AA infusion with or without DRT stimulation. Black bars under the bladder pressure traces indicate stimulation duration. Stimulation: 5 Hz, 0.2 millisecond, T = 0.3 V for S1, T = 0.18 V for S2. Infusion rate = 3 ml/min. (B) Normalized bladder capacity measured under different conditions (N = 20 cats). *Indicates significantly (P < 0.01) different from the AA control (one-way analysis of variance).
