Electrodiagnostic evaluation is arguably the best method for assessing a potential peroneal nerve insult. It is clinically difficult to isolate and test the short head of the biceps, the evaluation of which is critical in determining whether a lesion is proximal to the knee and whether it involves the sciatic nerve, the lumbosacral plexus, or nerve roots. In patients with exercise-induced symptoms, electrodiagnostic tests should be performed before and after exercise. Such tests include sensory and motor conduction studies, as well as needle EMG.
