Conventional electromyography was used to measure motor unit potential duration in the external anal sphincter in normal subjects and patients with idiopathic faecal incontinence. The results revealed a direct correlation between age and mean motor unit potential duration in control subjects, but no differences between age-matched male and female subjects. Patients with faecal incontinence exhibited prolongation of mean motor unit potential duration compared with matched controls. This technique provided useful quantitative data on reinnervation within the anal sphincter, complementing the results of single fibre electromyography.
采用传统肌电图测量正常受试者和特发性大便失禁患者肛门外括约肌的运动单位电位持续时间。结果显示,对照组中年龄与平均运动单位电位持续时间呈直接相关,但年龄匹配的男性和女性受试者之间无差异。与匹配的对照组相比,大便失禁患者的平均运动单位电位持续时间延长。该技术提供了关于肛门括约肌内神经再支配的有用定量数据,补充了单纤维肌电图的结果。
