Key result
Early EMG testing in children with Erb's palsy revealed high-voltage polyphasic motor unit potentials, suggesting brachial plexus injury occurred several weeks before delivery.

Early EMG may indicate prenatal injury in some Erb's palsy cases; leaves open timing attribution and requires prospective validation before clinical or medicolegal use.
Case Report (n=79)
Early EMG testing in congenital brachial paralysis can help identify prenatal injuries, which has significant clinical and medicolegal implications.
Paradiso et al. (1997) conducted a case report in Erb's palsy (n=79). Early EMG testing was evaluated on EMG pattern and clinical features of injury. Early EMG testing in children with Erb's palsy revealed high-voltage polyphasic motor unit potentials, suggesting brachial plexus injury occurred several weeks before delivery.
