Biofeedback versus electrical stimulation for sexual dysfunction: a randomized clinical trial

Abstract

Sexual dysfunction is a common problem in the general population. We compared the effects of biofeedback and electrical stimulation on the symptoms of sexual pain dysfunction in women with urinary stress incontinence. We carried out a parallel randomized clinical trial in an outpatient department for physical medicine and rehabilitation at a university hospital. Based on DSM-5 criteria for sexual dysfunction, 22 patients with sexual dysfunction and stress incontinence were included and randomly allocated to each study arm. The primary outcome measure was the total score on the Female Sexual Function Index. Each group underwent pertinent treatment for 100min, two times a week for 6weeks. Both groups showed favorable outcomes in increasing Female Sexual Function Index mean scores and their domains. However, for improving sexual function, women in the biofeedback group benefited more than those receiving electrical stimulation. Biofeedback raised desire, arousal, lubrication, orgasm, and satisfaction scores more than electrical stimulation (all p ≤ 0.025). Both interventions decreased pain during or following vaginal penetration similarly (p =0.985). Both biofeedback and electrical stimulation increased the Female Sexual Function Index score. However, to improve sexual function, women undergoing biofeedback seem to benefit more than those receiving electrical stimulation. We recommend considering the prescription of biofeedback for the treatment of sexual dysfunction because of its efficacy, lack of adverse effects, and easy application.
