Continence scores and anal manometry are commonly used to assess the effect of electrostimulation in fecal incontinence. This study determined the increase of muscular compound potentials in electroneurography of the pudendal nerve after three months of electrostimulation treatment.
Thirty women were tested; their average age was 46.8 (standard deviation, 9.82) years. Electrostimulation was applied twice daily for 15 minutes in each case.
Before treatment, amplitudes were, on average, 0.54 mV (standard deviation, 0.2). After three months of electrostimulation, the amplitudes had increased to 0.84 mV (standard deviation, 0.2). The continence score was improved from 8.73 to 7.1 points.
We believe that by electrostimulation the atrophic muscle can be trained to stabilize the pelvic floor, thus increasing anal pressure and, thereby, creating a basis for adequate voluntary contraction. Electrostimulation is, therefore, especially suitable for functional deficits of the external anal sphincter (insufficient voluntary contractions because of atrophic muscle) without identifiable muscular lesion.
尿失禁评分和肛门测压常用于评估电刺激对大便失禁的治疗效果。本研究旨在确定经三个月电刺激治疗后，阴部神经神经电图中肌肉复合电位的增加情况。
对30名女性进行了测试；她们的平均年龄为46.8（标准差9.82）岁。每种情况下，电刺激每天进行两次，每次15分钟。
治疗前，平均波幅为0.54mV（标准差0.2）。经过三个月的电刺激后，波幅增加到了0.84mV（标准差0.2）。尿失禁评分从8.73分提高到了7.1分。
我们认为，通过电刺激可训练萎缩的肌肉以稳定盆底，从而增加肛门压力，进而为充分的自主收缩创造基础。因此，电刺激特别适用于无明显肌肉病变的肛门外括约肌功能缺陷（因肌肉萎缩导致自主收缩不足）。
