Approximately six hours of biofeedback training was given to eight fecally incontinent children with myelomeningocele in order to establish bowel control. Their ages ranged from five to 15 years. The patients were shown a polygraph tracing of the external anal sphincter while they were being encouraged voluntarily to contract the sphincter when the rectum was distended with progressively larger volumes of air in a balloon. Seven of the eight patients showed normal sensation for rectal distension. Following this training period, five of the children had no incontinent periods, and two of these had discontinued enemas or suppositories. A sixth patient had an 80 per cent reduction in the frequency of incontinence. The remaining two did not benefit. At follow-up between 13 and 24 months later, four children were incontinent once a month or less often; two others were incontinent once per day, a considerable decrease from the pretraining period. The two children who failed to learn were still incontinent at follow-up. These results show that fecally incontinent patients with myelomeningocele can learn to evacuate normally or to reduce soiling after a relatively short period of biofeedback training.
为了实现肠道控制，对八名患有脊髓脊膜膨出的大便失禁儿童进行了约六小时的生物反馈训练。他们的年龄在5岁至15岁之间。当用逐渐增大体积的气球向直肠充气使直肠扩张时，向患者展示肛门外括约肌的测谎仪记录图，同时鼓励他们自愿收缩括约肌。八名患者中有七名对直肠扩张有正常感觉。经过这段训练期后，五名儿童不再有失禁期，其中两名不再使用灌肠剂或栓剂。第六名患者的失禁频率降低了80%。其余两名患者没有受益。在13至24个月后的随访中，四名儿童每月失禁一次或更少；另外两名儿童每天失禁一次，与训练前相比有相当大的减少。两名未能学会的儿童在随访时仍失禁。这些结果表明，患有脊髓脊膜膨出的大便失禁患者在经过相对较短的生物反馈训练期后，可以学会正常排便或减少弄脏情况。
