Electrophysiological features in the management of meralgia paraesthetica.

Meralgia paraesthetica is a condition which presents with pain and paresthesia over the anterolateral thigh, due to entrapment of the lateral femoral cutaneous nerve. Our local experience of 12 cases highlights the usefulness of antidromic sensory nerve conductions in the diagnostic and prognostic aspects of this condition. Follow-up studies suggest that patients with initial reduction rather than absent sensory amplitudes on the affected side more likely to experience symptomatic improvement over an 8 to 24 month period.
