Clinical examination versus routine and paraspinal electromyographic studies in predicting the site of lesion in brachial plexus injury.

Purpose: To study the role of clinical examination, routine electromyography (EMG), and paraspinal EMG individually and in combination to predict the site of lesion in brachial plexus injury.

Methods: Forty cases of brachial plexus injury were evaluated clinically. They then were subjected to routine and paraspinal EMG.
