Abstract
The use of wire electrodes inserted intramuscularly has become quite common in electromyographic studies. Such electrodes have the advantages, relative to needle electrodes, of small size and great flexibility, resulting in minimum discomfort. The usual techniques for inserting these electrodes, [1], [2], necessitate forming a hook on the end of the electrode. This hook serves to keep the electrode in the hypodermic needle during insertion, and to anchor the electrode in the muscle during withdrawal of the needle.
