RESUMO
Objective To explore clinical value of intraoperative extra strong electrical stimulation in the treatment of birth brachial plexus palsy. MethodsFrom July 2008 to September 2011,intraoperative extra strong electrical stimulation was applied in 9 cases of incomplete birth brachial plexus palsy after neurolysis.The latency and amplitude of compound muscle action potentials before and after electrical stimulation were recorded and the extent of improvement was compare.ResultsThe latency was improved in 7 cases with 8.02％ in average,amplitude in 8 cases with 185.97％ in average.The related nerve recover partial motor function in 8 cases in 2 weeks after operation.ConclusionIntraoperative extra strong electrical stimulation is a effective assistant technique to promote motor functional recovery of birth brachial plexus palsy.
