To investigate the application effects of pelvic floor myoelectric stimulation combined with biofeedback therapy on female post-stroke urinary incontinence patients.

A total of 71 female post-stroke urinary incontinence patients admitted to the Second Affiliated Hospital of Xinjiang Medical University from July 2021 to July 2022 were included. They were divided into the experimental group (35 cases) and the control group (36 cases) using a random number table. The control group underwent conventional treatment, while the experimental group received pelvic floor myoelectric stimulation combined with biofeedback therapy plus the conventional treatment. After undergoing the two different treatment methods, the surface electromyography values of pelvic floor muscles (baseline during quiet rest, maximum value during fast contraction, average value during endurance contraction), scores on the International Consultation on Incontinence Questionnaire-Short Form (ICI-Q-SF), and General Self-Efficacy Scale (GSES) were compared between the two groups. For normally distributed data, t-tests were used; for non-normally distributed data, the Mann-Whitney U test was employed.

Compared with the control group, the experimental group had a lower pre-baseline mean value of surface electromyography of the pelvic floor muscles during the pre-resting phase [(5.22±2.76) μV vs (6.27±2.75) μV], a higher mean endurance contraction value during the slow twitch endurance contraction phase [(19.84±6.22) μV vs (14.90±5.00) μV], the differences were statistically significant (t=-3.124, 3.694, P=0.003, <0.001); however the maximum muscle contraction in the experimental group was significantly higher than that in the control group during the rapid contraction phase [(53.81±17.49) μV vs (45.16±17.70) μV], the difference was statistically significant (t=2.071, P=0.042). The GSES score in the experimental group was higher than that of the control group [23.00 (20.00,27.00) vs 17.00 (15.00, 21.00)], and the ICI-Q-SF assessment score in the experimental group was lower than that of the control group [8.00 (5.00,9.00) vs 9.00 (6.25, 11.00)], the differences were statistically significant (Z=-3.959, -1.974, P＜0.001, =0.048).

Pelvic floor myoelectric stimulation combined with biofeedback therapy can effectively alleviate the symptoms of urinary incontinence in female post-stroke patients.
