The latency of the response in the external anal sphincter muscle following transcutaneous stimulation of the cauda equina at the L1 vertebral level was measured in nine women with neurogenic faecal incontinence (mean 7.3 SD 0.7 ms) and 11 normal subjects (mean 5.6 SD 0.6 ms) (p = 0.01). There was no difference in conduction velocity between the L1 and L4 vertebral levels thus supporting the suggestion that conduction delay in faecal incontinence occurs distally.
在9名患有神经源性大便失禁的女性(平均7.3,标准差0.7毫秒)和11名正常受试者(平均5.6,标准差0.6毫秒)中,测量了在L1椎体水平经皮刺激马尾神经后肛门外括约肌肌肉反应的潜伏期(p = 0.01)。L1和L4椎体水平之间的传导速度没有差异,因此支持了大便失禁传导延迟发生在远端的观点。
