Summary— The distal motor latencies in the perineal and pudendal nerves were measured in 20 normal subjects using digitally directed pudendal nerve stimulation. The mean pudendal and perineal nerve latencies were 1.9 ms ± 0.2 (SD) and 2.4 ms ± 0.2 (SD) respectively. In a further eight normal subjects transcutaneous spinal stimulation was used to record the motor latency from L1 and L4 stimulation sites to the urethral striated sphincter musculature. The mean spinal nerve terminal latencies from L1 and L4 were 4.9 ms ± 0.3 (SD) and 4.1 ms ± 0.2 (SD) respectively. These techniques can be applied to the investigation of the nerve supply to the urethral striated musculature in stress urinary incontinence and other disorders affecting the innervation of the anterior pelvic floor musculature.
