1. A method for localizing a needle to a nerve, the method comprising: inserting the needle into a patient; using the inserted needle to electrically stimulate the nerve, with a known current intensity, so as to evoke a nerve response; electronically detecting the nerve response through an electrode placed on the patient; analyzing the electronically detected nerve response so as to identify at least one attribute of the same; confirming that the inserted needle is in the immediate proximity of the nerve based upon known current intensity and at least one identified attribute of the electronically detected nerve response; and detecting neuropathies in the nerve based upon at least one identified attribute of the detected nerve response.
