English Standardized experimental nerve crush attempts should include the number, duration, and intensity (amount of pressure) of crushes. The authors have developed a new crushing device, a clamp with which predetermined forces can be applied to nerves. This allows the exertion of different, standardized forces to crush a nerve within a scale that produces second-degree injuries. The main advantages of the clamp are that it is small, although very robust, is purely mechanical, and is easy to handle. The jaws of the clamp are not serrated, so that pressure on the nerve is uniformly transmitted. To avoid unintended nerve damage, the edges of the jaws are smoothly rounded off. The closure of the clamp is mechanized by a spring. As the spring is exchangeable, any number of different preloads are available. The force can be varied, according to different requirements, and is applicable to variantly thick nerves in any experimental animal, thus enhancing standardization, and making cross-over comparisons of experimental study results possible.
