[Electroacupuncture at points for erectile dysfunction after stroke: a randomized controlled trial].

Objective: To observe the clinical effect of electroacupuncture at points in patients with erectile dysfunction after stroke.

Methods: A total of 58 patients with erectile dysfunction after stroke were randomly divided into an observation group (29 cases, 1 case dropped off, 1 case discontinued) and a control group (29 cases, 1 case dropped off). Both groups were given basic treatment, including routine medical treatment, routine acupuncture treatment, rehabilitation training and pelvic floor biofeedback electrical stimulation treatment. The observation group was treated with electroacupuncture at points, and the control group was treated with shallow acupuncture combined with electroacupuncture at the control points (8 points at 20 mm horizontally beside points), continuous wave, frequency in 50 Hz, current intensity in 1-5 mA, 5 times a week for 4 weeks. The 5-item version of the international index of erectile function (IIEF-5) score, erectile dysfunction effect on quality of life (ED-EQoL) score and pelvic floor muscle contraction amplitude were compared between the two groups before and after treatment.

Results: After treatment, the IIEF-5 scores and the contraction amplitude of fast muscle fiber, comprehensive muscle fiber and slow muscle fiber in the two groups were higher than those before treatment (<0.05), the ED-EQoL scores were lower than those before treatment (<0.05), and the changes of above indexes in the observation group were larger than the control group (<0.05).

Conclusion: Electroacupuncture at points can improve the erectile function of patients with erectile dysfunction after stroke, increase the contraction amplitude of pelvic floor muscles, and promote the quality of life of patients.
