Answer

The value of electrodiagnostic studies for superficial peroneal nerve injury varies in the literature. In many cases, findings from electrodiagnostic tests are normal because these dynamic syndromes frequently improve or resolve at rest; however, in some instances, these tests may reveal an unrecordable evoked response or a prolonged distal latency of a segment of the nerve and thus help better define the zone of compression. Such tests also help in the evaluation of concomitant radiculopathy or peripheral neuropathy.
