In terms of the recovery of nerve conduction and amplitude , the results in EA plus WN group -LSB- ( @ + / -@ ) m/s , ( @ + / -@ ) , microVx@ @ -RSB- were better than the other two groups -LSB- ( @ + / -@ ) m/s , ( @ + / -@ ) microV X @ @ , ( @ + / -@ ) m/s , ( @ + / -@ ) microV X @ @ -RSB- ( P < @ ) .
