We studied the voluntary contractile activity of the ischiocavernosus muscle (ICM) in 21 sexually potent and 97 erectile dysfunction (ED) subjects using a spring balance. A strap was placed around the coronal grove of the glans penis and tensioned with the spring balance. Subjects were asked and encouraged to contract the ICM against the spring balance. We evaluated the length of stroke, duration of contraction, and maximum contractile force. The length of stroke, duration of contraction, and maximum contractile force showed statistically significant differences between potent and ED subjects. Diagnosed psychogenic ED and arteriogenic ED showed higher contractile activity than cavernous ED and neurogenic ED. Our results corresponded to those of previous studies that have urged consideration of the role of the ICM during the process of erection in animal experiments and in human electrophysiological studies. The spring balance evaluation is a useful, inexpensive method for evaluating the ICM.

坐骨神经肌肉的弹簧平衡评估。

我们使用弹簧秤研究了21名性功能旺盛的男性和97名勃起功能障碍（ED）受试者的海鞘肌肉（ICM）的自愿收缩活动。将带子放在龟头的冠状树林周围，并用弹簧秤拉紧。要求受试者并鼓励他们根据弹簧平衡来收缩ICM。我们评估了中风的长度，收缩的持续时间和最大收缩力。脑卒中的长度，收缩的持续时间和最大收缩力在有力的和ED受试者之间显示出统计学上的显着差异。经诊断的心源性ED和动脉源性ED显示出比海绵状ED和神经源性ED更高的收缩活性。我们的结果与先前的研究结果相符，这些研究敦促考虑在动物实验和人体电生理研究中勃起过程中ICM的作用。弹簧平衡评估是一种用于评估ICM的有用，廉价的方法。
