Ulnar neuropathy Electrodiagnosis EMG Sensitivity Specificity KEY POINTS. The most common locations for Ulnar mononeuropathy are at the retroepicondylar (RTC). groove and the humeroulnar arcade. Precise localization of the Ulnar nerve below and above the elbow with submaximal stimulations improves accuracy of the distance measurement. The factors that can lead to spuriously low nerve conduction velocity (NCV) across the elbow include a cold elbow and falsely low distance measurements. Multiple internally consistent abnormalities should be present to ensure accurate diagnosis of Ulnar neuropathy at the elbow.
