RESUMEN
Objective:To study the Clinical efficacy of combined therapy of adenosylcobalamin and transcutaneous eletrical nerve stimulation(TENS)in the treatment of postherpetic neuralgia(PHN).Method:Sixty patients with PHN were randomly divided into 3 groups:group A treated with TENS.group B treated with adenosylcobalamin,group C treated with adenosylcobalamin and TENS based on the management of groups A and B.The three groups had all been treated for 10d.Result:In observation,visual analogue scale(VAS)and 5 grade pain scores of group C were lower than those of groups A and B;VAS and 5 grade pain scores differences of group C were higher than those of groups A and B:The effective rate of group C(100%)was higher than that of groups A and B respectively.The differences were significant(P<0.05).Conclusion:Combined therapy of adenosylcobalamin and TENS is effective for the treatment of PHN and can alleviate pain and improve sleep.
