Therapeutic effect of biofeedback stimulation combined with hypogastric plexus blocking on chronic pelvic pain / 实用医学杂志

ABSTRACT

Objective To study the clinical effect of biofeedback stimulation combined with hypogastric plexus blocking on chronic pelvic pain.Methods Sixty of patients with chronic pelvic pain(CPP)were randomly divided into the biofeedback stimulation group(BF group,n = 20),the continuous abdominal block group(NB group,n = 20)and the combination group(BF-NB Group,n = 20). The BF group was treated with biofeedback electrical stimulation for 2 months,while the NB group was treated with continuous hypogastric plexus blocking for 2 weeks and the BF-NB group was pre-treated with 2 weeks of hypogastric plexus blocking and then underwent biofeedback electrical stimulation for 2 months. We recorded the visual analogue scale(VAS)scores before treatment,2,4,8 weeks and 3 months after the treatment and adverse events.Results The VAS scores of the BF-NB group at 2,4,8 weeks and 3 months after treatment were significantly lower than those before treatment and the other groups(P<0.05).The significantly effective rate and total effective rate of the BF-NB group were signifi-cantly higher than those before treatment of the BF group and the NB group(P < 0.05). There was no significant difference in rate of adverse events between the BF-NB group and the NB group(P>0.05).Conclusion The bio-feedback electrical stimulation combined with the hypogastric plexus block is a safe and effective method to relieve chronic pelvic pain.
