Effect of pelvic floor muscle training on pelvic floor muscle function and lower urinary tract symptoms in stroke patients: a systematic review.

Background: Pelvic floor muscle (PFM) dysfunction and lower urinary tract symptoms (LUTS) are common in stroke patients. Although pelvic floor muscle training (PFMT) is a promising intervention, its effects on stroke patients have not been fully studied.

Objective: The goal of this study was to conduct a systematic review of the effect of PFMT on PFM and urinary function of stroke patients.

Methods: The databases AMED, MEDLINE, CINAHL, Cochrane Library, and PEDro were searched for title/abstract on PFMT and stroke. RCTs and quasi-experimental trials that compared the effects of PFMT to a control intervention in stroke patients were included. The RoB 2.0 and ROBINS-I were used to assess the methodological quality of the included studies. The Standardized mean difference (SMD) and its 95% confidence interval (CI) were calculated.

Results: The current review included three RCTs and one quasi-experimental study, all of which were moderate to high quality. The analysis revealed that PFMT significantly improved PFM contraction (SMD: 0.92; 95% CI, 0.47 to 1.38; < .0001), dynamic endurance (SMD: 0.61; 95% CI, 0.06 to 1.16; = .030), daytime frequency (SMD: -0.81; 95% CI, -1.37 to -0.25; = .004), ICIQ-SF (SMD: -1.64; 95% CI, -2.39 to -0.89; < .0001), and LUTS (SMD: -1.82; 95% CI, -2.67 to -0.96; < .0001). Differences in PFM strength, static endurance, nocturia, UI frequency, and 24-hour pad weight were insignificant or non-existent between the two groups.

Conclusion: This review demonstrates that PFMT improves PFM contraction, PFM dynamic endurance, daytime frequency, and overall LUTS in stroke patients. To validate these findings, well-designed RCTs with large sample sizes and reliable outcome measures should be conducted.
