RESUMEN
PURPOSE: The aim of this study is to identify and critically evaluate literature regarding the clinical efficacy of extracorporeal magnetic innervation (ExMI) in the treatment of female patients with urinary incontinence (UI). METHODS: An analysis was carried out using the following electronic databases: Medline, PubMed, ScienceDirect, and the Cochrane Library (data published between 2008 and 2023). Searches of the above databases were conducted in April 2023. Only randomized clinical studies (RCTs) in English studies were eligible for the study. Randomized controlled trials were included in the review and evaluated with the Downs and Black checklist. RESULTS: Eleven studies met the inclusion criteria. Among these, two studies examined the use of ExMI and PMFT (pelvic floor muscle training) and three studies compared active ExMI versus sham ExMI. Four studies evaluated solely ExMI, and moreover, there was no control group in two of these studies. One study compared the effects of Kegel exercises with ExMI, while another study compared electrostimulation with ExMI. The reviewed studies exhibited significant differences in interventions, populations, and outcome measures. CONCLUSIONS: Extracorporeal magnetic stimulation has shown promise as an effective treatment for female urinary incontinence. Whether used alone or as a component of combination therapy, ExMI has the potential to enhance patients' quality of life (QoL) without significant safety concerns.
RESUMEN
OBJECTIVE: The purpose of this study is to assess the effectiveness of pelvic floor muscle training and extracorporeal magnetic innervation in treatment of urinary incontinence in women with stress urinary incontinence. METHODS: The randomized controlled trial enrolled 128 women with stress urinary incontinence who were randomly allocated to either one out of two experimental groups (EG1 or EG2) or the control group (CG). Subjects in the experimental group 1 (EG1) received 12 sessions of pelvic floor muscle training, whereas subjects in the experimental group 2 (EG2) received 12 sessions of extracorporeal magnetic innervation. Subjects in the control group (CG) did not receive any therapeutic intervention. The following instruments were used to measure results in all study groups at the initial and final assessments: Revised Urinary Incontinence Scale (RUIS), Beck Depression Inventory (BDI-II), General Self-Efficacy Scale (GSES), and King's Health Questionnaire (KHQ). RESULTS: In both experimental groups, a statistically significant decline in depressive symptoms (BDI-II) and an improvement in urinary incontinence severity (RUIS) and quality of life (KHQ) were found in the following domains: "social limitations," "emotions," "severity measures," and "symptom severity scale." Moreover, self-efficacy beliefs (GSES) improved in the experimental group that received ExMI (EG2). No statistically significant differences were found between all measured variables in the control group. Comparative analysis of the three study groups showed statistically significant differences at the final assessment in the quality of life in the following domains: "physical limitations," "social limitations," "personal relationships," and "emotions." Conclusion. Pelvic floor muscle training and extracorporeal magnetic innervation proved to be effective treatment methods for stress urinary incontinence in women. The authors observed an improvement in both the physical and psychosocial aspects.
