In 1939 Katz had mathematically defined the intensity-duration curve, and it has been used in this form to this day. In 1990, Ljubin and Knesaurek proposed the new mathematical and graphic form of the intensity-duration curve as a line. The new form, both graphic and mathematical, is considered to be more accurate and it is a new contribution to research into neuromuscular excitability. Besides, this method also makes possible a modern, numerical presentation of the clinical results and gives a new insight into observation of neuromuscular excitability, both in physiological conditions and pathology. Stephen's graphs, as well as of other authors, showing the intensity duration curves can also be transformed into lines, by translating them into the coordinate system with both logarithmic axes.
1939年，卡茨从数学角度定义了强度-持续时间曲线，至今仍以这种形式被使用。1990年，柳宾和克内绍雷克提出了强度-持续时间曲线新的数学和图形形式，即一条直线。这种新形式，无论是图形还是数学形式，都被认为更准确，是对神经肌肉兴奋性研究的一项新贡献。此外，这种方法还使临床结果能够以现代的数值形式呈现，并为在生理条件和病理情况下观察神经肌肉兴奋性提供了新的视角。斯蒂芬以及其他作者展示强度-持续时间曲线的图表，也可以通过将其转换到双对数坐标轴的坐标系中而转化为直线。
