Myoelectrical and myomechanical activities of the distal portion of the jejunum and pelvic flexure were studied in 7 ponies, using permanently implanted monopolar and bipolar stainless steel electrodes. Dental acrylic embedded recording electrodes were surgically sutured to the serosal surface of the distal portion of the jejunum and pelvic flexure. Myoelectrically, regular spike bursts and irregular spike bursts were observed in the jejunum. Short spike bursts and long spike bursts were recorded and associated with spike potentials, using impedance recording techniques. Electrical and mechanical data could be monitored simultaneously from the same recording electrode, using separate channels on a physiograph. This method proved effective to monitor periodically myomechanical activity at the same time that myoelectrical activity was being evaluated. The recording system required fewer recording devices to be attached to the intestinal tract, was an inexpensive method of obtaining myomechanical recordings, and did not alter markedly the myoelectrical activity when mechanical activity was being monitored.
使用永久植入的单极和双极不锈钢电极，对7匹小马的空肠远端和骨盆弯曲部的肌电和肌机械活动进行了研究。牙科丙烯酸包埋的记录电极通过手术缝合到空肠远端和骨盆弯曲部的浆膜表面。在肌电方面，在空肠中观察到规则的尖峰群和不规则的尖峰群。使用阻抗记录技术记录了短尖峰群和长尖峰群，并将其与尖峰电位相关联。利用生理记录仪上的单独通道，可以从同一个记录电极同时监测电和机械数据。该方法被证明在评估肌电活动的同时定期监测肌机械活动是有效的。该记录系统需要连接到肠道的记录设备较少，是一种获取肌机械记录的廉价方法，并且在监测机械活动时不会明显改变肌电活动。
