Abstract

In an article which is to appear shortly in the Archives of Neurology, an instrument, called a "chronomyometer," for testing muscles whose nerve supply has been interfered with, is to be described. Evidence will be presented to show that when a nerve injury is complete and the patient is seen months after injury nonoperative treatment and careful electrical examinations are the procedures of choice, within certain limits. If, however, the nerve injury is complete and the patient is seen early, the method here described would seem to make early exploration of the nerve the method of choice.

When one explores an injured nerve and finds the nerve intact but thinned out or greatly thickened at some point, the question arises: Are axis cylinders passing through this area? If they are regenerating, the nerve should not be cut and resutured, but if they are not regenerating and sufficient time has elapsed
