Efeitos da técnica de eletroestimulação parassacral em mulheres com bexiga neurogênica hiperativa pós Acidente Vascular Encefálico

Abstract

Objective: The aim of this study was to evaluate the effects of the parasacral electrostimulation technique in women with hyperactive neurogenic bladder after stroke. Methodology: The sample consisted of 11 female patients, aged between 40 and 70 years, who had ischemic or hemorrhagic stroke for over a month, with overactive bladder. Before and after the intervention, participants were assessed for the impact of urinary leakage by the ICIQ-SF questionnaire; quality of life by WHOQOL-bref and three-day voiding diary. The women received treatment for 12 sessions twice a week using the Neurodyn transcutaneous electrical nerve stimulation device (TENS) (IBRAMED®, Brazil). The patient was positioned prone and the electrodes placed on either side of S2 and S3 in the sacral region and fixed to the skin with tape. TENS current (F = 10Hz, 200ms) was applied for 30 minutes. The current intensity was increased respecting the patients' sensory threshold. To compare the variables before and after the intervention, the t-test was applied. Results: A significant reduction in the ICIQ-SF questionnaire values (p <0.001) and a significant reduction in frequency (p = 0.007) and urinary losses (p <0.001) after the intervention. In the quality of life domains, there was a substantial improvement in the psychological (p = 0.006) and environment (p = 0.018) domains, with no changes in the physical (p = 0.309) and social relationships (p = 0.871) domains. Conclusion: After the intervention there was a significant reduction in the impact of urinary leakage, frequency and urinary leakage and improvement of quality of life in the psychological and environmental domains. Therefore, the research results support the choice of parasacral electrostimulation in women with post-stroke hyperactive neurogenic bladder, as it has positive results in the management of this clinical condition.
