In terms of the recovery of nerve conduction and amplitude , the results in EA plus WN group [ ( 50.9 + / -4.6 ) m/s , ( 8.8 + / -2.9 ) , microVx1 000 ] were better than the other two groups [ ( 43.7 + / -3.1 ) m/s , ( 4.2 + / -1.9 ) microV X 1 000 , ( 43.8 + / -3.3 ) m/s , ( 4.5 + / -2.2 ) microV X 1 000 ] ( P < 0.05 ) .
