An artificial erection was induced in nine patients consulting for erectile dysfunction. Changes in the intracavernous pressure (ICP) and in the integrated EMG of the ischiocavernosus muscle were recorded during voluntary muscular contractions. During such contractions elevations in ICP, varying between 100 and 525 mm. Hg, were recorded. Changes in ICP were always in phase with changes in the integrated electromyogram (EMG) of the ischiocavernosus muscle, and correlations between the duration of changes showed an almost perfect linear relationship between both physiological events. Correlations between maximum changes in ICP and integrated EMG generally showed a positive relationship between both measures. Results are interpreted to suggest involvement of the ischiocavernosus muscle in the process of penile rigidity.
对9名因勃起功能障碍前来咨询的患者进行了人工勃起诱导。在自愿肌肉收缩期间记录海绵体内压力（ICP）和坐骨海绵体肌的肌电图积分（EMG）变化。在这种收缩过程中，记录到ICP升高，范围在100至525毫米汞柱之间。ICP的变化始终与坐骨海绵体肌的肌电图积分（EMG）变化同步，并且变化持续时间之间的相关性表明这两种生理事件之间几乎呈完美的线性关系。ICP最大变化与EMG积分之间的相关性通常表明这两种测量之间呈正相关。结果被解释为提示坐骨海绵体肌参与了阴茎勃起过程。
