Median and Ulnar 14-cm Antidromic Sensory Studies to the Third and Fifth Digits-A Comparison of Amplitude.

There are multiple reports of peripheral nerve injury following the implantation or removal of surgical hardware. Electrodiagnostic testing can be useful in assessing the chronicity, severity, and recovery of such a nerve injury. The purpose of this study is to establish a normative data set to allow for comparison of median and ulnar antidromic sensory peak-to-peak amplitude values.
