ABSTRACT
Objective To explore the values of electromyography to examine birth injuries.Methods 34 cases of birth injuries were studied,the electromyography and motor nerve conduction of brachial plexcy were recorded.Then,the location and severity of birth injuries were determined.Results Among 34 cases,according to the location of injuries,there were 10 cases of upper trunk injuries,7 cases of upper and middle trunk injuries,5 cases of middle and lower trunk injuries,5 cases of lower trunk injuries,and 7 cases of whole brachialplexus injuries.On the other hand,according to the severity of injuries,there were one case of complete injuries and 33 cases of incomplete injuries which included 2 cases of severe injuries and 31 cases of slight injuries.Conclusion Electromyography is the reliable method to identify the location and severity of brachial plexus injuries,and this examination is necessary to diagnose birth injuries with great clinical values.
