ABSTRACT
OBJECTIVE: Overactive bladder (OAB) is a common condition in older women, characterized by urinary urgency, frequency, and nocturia. This study compared the efficacy and safety of thread-embedding acupuncture (TEA) and sham TEA in postmenopausal women with OAB.
METHODS: In this multicenter, randomized, controlled trial, 68 postmenopausal women with OAB were allocated in a 1:1 ratio to receive TEA or sham TEA (manual acupuncture without thread embedding) once weekly for 8 weeks, followed by an 8-week follow up. The primary outcome was the mean daily voiding frequency over 3 days. Secondary outcomes included other bladder diary parameters, the Overactive Bladder Symptom Score (OABSS), and the King’s Health Questionnaire score.
RESULTS: At week 8, both groups showed reductions in 24-hour micturition frequency; however, after adjustment for baseline values using ANCOVA, no significant between-group difference was observed in the primary outcome. Repeated measures analysis demonstrated no significant group-by-time interactions for secondary outcomes, although significant improvements over time were observed in both groups. At follow-up, nighttime voiding remained significantly reduced from baseline in the TEA group, whereas this reduction was not statistically significant in the sham group; however, the between-group difference did not reach statistical significance. No serious adverse events were reported.
CONCLUSION: TEA and manual acupuncture were effective and safe in reducing OAB symptoms in postmenopausal women, with no significant differences between interventions. Larger, long-term studies are needed to clarify specific benefits of TEA.
