The surface electromyogram (EMG) of the masseter muscle and interocclusal force were recorded in six human subjects during fast and slow clenches. The simple linear force/EMG relation that applies for steady bite-force levels was inadequate to explain their relationship under conditions of changing force: a second component of force, its rate of change, was necessary. EMG/force equations for fast and slow clenches were broadly similar. The rate of change factor may account for the apparent EMG/force lag observed in earlier studies.
在六名人类受试者进行快速和慢速紧咬时，记录了咬肌的表面肌电图（EMG）和咬合间力。适用于稳定咬合力水平的简单线性力/肌电图关系不足以解释在力变化条件下它们之间的关系：力的第二个组成部分，即其变化率，是必要的。快速和慢速紧咬的肌电图/力方程大致相似。变化率因素可能解释了早期研究中观察到的明显的肌电图/力滞后现象。
