Clinical and electrodiagnostic features of sciatic neuropathies.Phys Med Rehabil Clin N Am. 2013 Feb; 24(1):107-20.PM
Sciatic neuropathy is the second most common neuropathy of the lower extremity and a common cause of foot drop. This article reviews the anatomy, clinical features, pathophysiology, and electrodiagnostic assessment of sciatic neuropathies. There are multiple potential sites of pathology, determined in part by the mechanism of insult, including trauma, compression, masses, inflammation, and vascular lesions. Diagnosis is augmented by careful electrodiagnostic studies and imaging to help distinguish sciatic neuropathy from other sources of pathology. Electrodiagnostic studies may also help in assessing for early recovery and in determining prognosis.
