Answer

If the patient has had previous episodes of radicular symptoms or previous spinal surgery, it may be useful both from a diagnostic perspective and from a medicolegal standpoint to perform initial electrodiagnostic studies as soon as possible after the appearance of new symptoms in order to differentiate later developments from preexisting disease.
