Acute Effect of Transcranial Direct Current Stimulation in Pelvic Floor Muscle Function in Young Healthy Women: Initial Findings of a Randomized Controlled Trial.
Introduction and hypothesis: Transcranial direct current stimulation (tDCS) can enhance muscle function in healthy individuals. However, it is unknown if tDCS associated with pelvic floor muscle training (PFMT) can improve pelvic floor muscle function (PFMF) in healthy women. The aim of this study was to investigate the acute effect of a single session of tDCS in PFMF compared with sham-tDCS in healthy women.
Methods: A double-blind, cross-over, randomized clinical trial was conducted with healthy, nulliparous and sexually active women. PFMF was assessed by bidigital palpation (PERFECT scale) and intravaginal pressure by a manometer (Peritron™). Participants randomly underwent two tDCS sessions (active and sham) 7 days apart. The electrode was positioned equal for both protocols, the anode electrode in the supplementary motor area (M1) and the cathode electrode in the right supraorbital frontal cortex (Fp2). The current was applied for 20 min at 2 mA in active stimulation and for 30 s in sham-tDCS. The tDCS applications were associated with verbal instructions to PFMT in a seated position. After each tDCS session PFMF was reevaluated.
Results: Twenty young healthy women (aged 23.4 ± 1.7 years; body mass index 21.7 ± 2.2 kg/m2) were included. No difference was observed in power, endurance, and intravaginal pressure of PFMF (p > 0.05). The number of sustained contractions improved from 3.0 (2.0-3.5) to 4.0 (3.0-5.0) after active-tDCS (p = 0.0004) and was superior to sham-tDCS (p = 0.01).
Conclusion: The number of sustained contractions of PFM improved immediately after a single active-tDCS session, with a difference compared with the post-intervention result of sham-tDCS in healthy young women.
期刊介绍:
The International Urogynecology Journal is the official journal of the International Urogynecological Association (IUGA).The International Urogynecology Journal has evolved in response to a perceived need amongst the clinicians, scientists, and researchers active in the field of urogynecology and pelvic floor disorders. Gynecologists, urologists, physiotherapists, nurses and basic scientists require regular means of communication within this field of pelvic floor dysfunction to express new ideas and research, and to review clinical practice in the diagnosis and treatment of women with disorders of the pelvic floor. This Journal has adopted the peer review process for all original contributions and will maintain high standards with regard to the research published therein. The clinical approach to urogynecology and pelvic floor disorders will be emphasized with each issue containing clinically relevant material that will be immediately applicable for clinical medicine. This publication covers all aspects of the field in an interdisciplinary fashion
