The influence of electrocution on the evolution of rigor mortis was studied on rats. Our experiments showed that: (1) Electrocution hastens the onset of rigor mortis. After an electrocution of 90 s, a complete rigor develops already 1 h post-mortem (p.m.) compared to 5 h p.m. for the controls. (2) Electrocution hastens the passing of rigor mortis. After an electrocution of 90 s, the first significant decrease occurs at 3 h p.m. (8 h p.m. in the controls). (3) These modifications in rigor mortis evolution are less pronounced in the limbs not directly touched by the electric current. (4) In case of post-mortem electrocution, the changes are slightly less pronounced, the resistance is higher and the absorbed energy is lower as compared with the ante-mortem electrocution cases. The results are completed by two practical observations on human electrocution cases.
在大鼠身上研究了电击对尸僵演变的影响。我们的实验表明：（1）电击会加速尸僵的出现。电击90秒后，死后1小时就会出现完全尸僵，而对照组则在死后5小时出现。（2）电击会加速尸僵的消退。电击90秒后，在下午3时出现首次显著消退（对照组为下午8时）。（3）在未直接接触电流的肢体中，尸僵演变的这些变化不太明显。（4）在死后电击的情况下，与生前电击相比，变化稍不明显，电阻更高，吸收的能量更低。通过对人体电击案例的两项实际观察完善了这些结果。
