Abstract

objective: To investigate the characteritics and the value of the electroghysiological exam of the obsteric brachial plexus palsy. Methods:In 27 patients with obstetric brachial plexus palsy, NCV and EMG were measured on a regular basis. Result: with 9 cases of Erb's palsy(33.3%),l 1 eases of upper and middle trunk palsy(40.7%) and 7 cases of total plexus palsy(26%) in the 27 cases investigated. The abnormity rate of both NCV and EMG in infants under 3 morths is 100%. In the follow-up check-ups within the next 3 to 6 months, the abnormity rate of EMG is higher than that of NCV. Conclusion: Erb's palsy and upper-middle trunk palsy count for a majority of cases of obstetric brachial plexus palsy, NCV and EMG display different characteristics and have different value at different stages of obstetric brachial plexus palsy.
