Abstract
Introduction and hypothesis: The aim was to investigate the feasibility of using an intravaginal intra-abdominal pressure (IAP) sensor worn by female runners during running to evaluate pelvic floor loading, and the association between IAP and running-induced stress urinary incontinence (RI-SUI).
Methods: Twenty-eight female runners participated in this cross-sectional study (15 with RI-SUI and 13 continent). Participants completed a 37-min treadmill running protocol instrumented with an intravaginal sensor measuring IAP, and a skin-mounted accelerometer measuring pelvic accelerations. Linear regression analyses evaluated the relationship between IAP and pelvic acceleration. One-way ANOVAs assessed the impact of running speed on IAP. Sensor dislodgement was recorded, and effect sizes (Cohen's d) were calculated for the comparison of IAP and accelerometry outcomes between runners with and without RI-SUI.
Results: Intra-abdominal pressure showed high variance and the sensor was expelled in almost 15% of participants. Positive associations were found between pelvic acceleration and both absolute peak and normalized IAP but explained only between 12% and 18.6% of the variance in the models. Pelvic acceleration during running was not associated with cumulative IAP. Peak IAP significantly increased with running speed. Although IAP tended to be higher in runners with RI-SUI than in continent runners (Cohen's d between 0.14 and 0.74), pelvic accelerations tended to be lower (Cohen's d between 0.02 and 0.55).
Conclusions: There is high variance in IAP recorded during running using an intravaginal sensor. Faster speeds increase pelvic floor loading. Runners with RI-SUI may experience higher IAP than continent runners, warranting investigation. Recruitment should include a 15% data loss rate owing to sensor expulsion.
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
