Electrodiagnostic evaluation of lower extremity mononeuropathies

This article discusses the anatomy of lower limb mononeuropathies and reviews the general approach to evaluating patients in the electrodiagnostic laboratory with suspected mononeuropathies of the lower limb. Through illustrative cases of patients presenting with a floppy foot, buckling knee, or painful foot, the approaches using nerve conduction studies and needle electromyography are reviewed, and the pattern of findings of peroneal, tibial, sciatic, femoral, and obturator neuropathies is shown.
