脳卒中後尿失禁に対する電針：系統的スコーピングレビュー

Electroacupuncture has gained considerable prominence in treating poststroke urinary incontinence. However, there is no systematic review on current topics and clinical findings on electroacupuncture for poststroke urinary incontinence. This scoping review was conducted to systematically summarize and overview the prevalent themes and research evidence of electroacupuncture for poststroke urinary incontinence.

PubMed, the Cochrane Library, Web of Science, Embase, CNKI, VIP, Wan Fang Data, and SinoMed databases were searched from inception to June 1, 2023. Relevant literature on electroacupuncture for poststroke urinary incontinence were identified. Two researchers filtered studies and extracted the information independently. Quantitative analysis and descriptive approach were used. The scoping review was conducted according to the PRISMA-ScR checklist.

A total of 58 publications were included, comprising 49 clinical studies, 2 reviews, 5 systematic reviews, and 2 conference abstracts. Chinese researchers conducted all the clinical studies and published them from 2008 to 2022. Electroacupuncture had definite therapeutic effects in treating poststroke urinary incontinence from various outcome measures. In the treatment of acupuncture for poststroke urinary incontinence, multiple commonly employed or recommended acupuncture points were identified in the context of electroacupuncture, including EX-HN1, BL23, RN3, RN4, BL32, SP6, GV20, RN6, and BL35. Notably, all the studies demonstrated promising outcomes, characterized by a statistically significant reduction in the severity of urinary incontinence and the commendable efficacy of electroacupuncture intervention.

Electroacupuncture as a secure and efficacious alternative intervention showed substantial therapeutic potential in treating poststroke urinary incontinence. Further exploration necessitates additional large-scale, well-designed studies and international collaboration to facilitate the comprehensive clinical evaluation of electroacupuncture therapy in poststroke urinary incontinence.
