The effect of pelvic floor muscle training on sexual function, depressive symptoms, and pelvic floor muscle performance in women with overactive bladder: a randomized controlled
摘要
Pelvic floor muscle training (PFMT) improves urethral pressure, reduces detrusor muscle overactivity, and helps suppress the micturition reflex, thus contributing to symptom control. This study aimed to investigate the effects of pelvic floor muscle training on sexual function, depressive symptoms, and pelvic floor muscle performance in women with overactive bladder (OAB).
MethodsThis study was conducted with 64 women (32 women: intervention group, 32 women: control group) who applied to Erzurum City Hospital Urology Polyclinic between December 1, 2021 and December 1, 2024. The study data were collected by Personal Information Form, Urinary Diary Follow-up Form, Overactive Bladder Questionnaire (OAB-V8), Female Sexual Function Index (FSFI), Sexual Quality of Life Scale-Woman (SQoL-F), Epidemiological Research Center Depression Scale (CES-D), Pelvic Floor Muscle Training Intervention Follow-up Form, Digital palpation (pelvic floor muscle strength measurement). In the intervention group, PFMT was performed for 6 weeks with biofeedback with the Simplex Device in accordance with the given PFMT intervention procedure.
ResultsFollowing the 6-week intervention, women receiving PFMT demonstrated significantly lower OAB symptom severity and depressive symptoms and significantly higher sexual function, sexual quality of life, pelvic floor muscle strength, contraction strength, and MVC% than women in the control group. They also showed significantly higher sexual quality of life, pelvic floor muscle contraction strength, maximum voluntary contraction (MVC%), and pelvic floor muscle strength (all p < 0.05). No significant between-group difference was observed in pelvic floor muscle relaxation values (p > 0.05).
ConclusionWomen receiving PFMT demonstrated lower OAB symptom severity and depressive symptom scores and higher sexual quality of life and pelvic floor muscle performance measures. Because female sexual function (FSFI) was the predefined primary outcome, findings related to secondary outcomes should be interpreted as exploratory.
