Pelvic floor function in elite nulliparous athletes

Pelvic floor disorders among amateur runners

BACKGROUND

Sports and physical activity are known risk factors for pelvic floor dysfunction (PFD). The aim of this study is to examine the impact of amateur running on PFD, quality of life (QoL), and sexual function.

METHODS

Amateur runners were contacted through social media. Their PFD, sexual function, and QoL were evaluated by self-reporting validated questionnaires (PFDI-20, PISQ-12, IIQ-7). They were divided by degree of effort into two categories, 'High effort' and 'Moderate effort'. The differences between the two groups were examined by a Mann-Whitney U Test, T-Test, and Chi-square test.

RESULTS

180 women were included. A high incidence of PFD was found among 'High effort' runners in comparison to 'Moderate effort' runners. In addition, women who scored above the median in the PFDI-20 showed significantly greater impairment in QoL and sexual function. Interestingly, the 'High effort' group reported experiencing higher intensity orgasms compared with women in the 'Moderate effort' group. A correlation was also found between the weekly running distance and the intensity of orgasm experienced (P value = 0.004).

CONCLUSION

'High effort' runners present a higher incidence of PFD in comparison to 'Moderate effort' runners. Professional pelvic floor muscle training counselling should be considered even for amateur runners. Future interventional physical therapy studies should be carried out in order to investigate preventative strategies.

Evolution of the human birth canal

It seems puzzling why humans have evolved such a small and rigid birth canal that entails a relatively complex process of labor compared with the birth canal of our closest relatives, the great apes. This study reviewed insights into the evolution of the human birth canal from recent theoretical and empirical studies and discussed connections to obstetrics, gynecology, and orthopedics. Originating from the evolution of bipedality and the large human brain million years ago, the evolution of the human birth canal has been characterized by complex trade-off dynamics among multiple biological, environmental, and sociocultural factors. The long-held notion that a wider pelvis has not evolved because it would be disadvantageous for bipedal locomotion has not yet been empirically verified. However, recent clinical and biomechanical studies suggest that a larger birth canal would compromise pelvic floor stability and increase the risk of incontinence and pelvic organ prolapse. Several mammals have neonates that are equally large or even larger than human neonates compared to the size of the maternal birth canal. In these species, the pubic symphysis opens widely to allow successful delivery. Biomechanical and developmental constraints imposed by bipedality have hindered this evolutionary solution in humans and led to the comparatively rigid pelvic girdle in pregnant women. Mathematical models have shown why the evolutionary compromise to these antagonistic selective factors inevitably involves a certain rate of fetopelvic disproportion. In addition, these models predict that cesarean deliveries have disrupted the evolutionary equilibrium and led to new and ongoing evolutionary changes. Different forms of assisted birth have existed since the stone age and have become an integral part of human reproduction. Paradoxically, by buffering selection, they may also have hindered the evolution of a larger birth canal. Many of the biological, environmental, and sociocultural factors that have influenced the evolution of the human birth canal vary globally and are subject to ongoing transitions. These differences may have contributed to the global variation in the form of the birth canal and the difficulty of labor, and they likely continue to change human reproductive anatomy.

Long-Term Improvement in Urinary Incontinence in an Elite Female Athlete Through the Laser Treatment: A Case Report

Stress urinary incontinence (SUI) is increasing in elite female athletes (EFAs), affecting competition results and quality of life. Pelvic floor muscle training (PFMT) is the first-line treatment for SUI, and surgery is generally performed when PFMT is insufficient. However, in EFA, there are few cases in which surgery is performed and fewer reports. Therefore, there is no known general treatment strategy for EFA with SUI. In our study, a 23-year-old track-and-field medalist with severe SUI was successfully treated with a vaginal and urethral erbium-doped yttrium aluminum garnet laser (VEL + UEL). After 12 treatments over one year, urinary incontinence decreased from 300 mL or more in the 400 m track run before treatment to 0 mL. She did not experience any more problems during running or competition. There was no recurrence of SUI for three years, and the urethral pressure profile examination confirmed improvement. MRIs showed that the left puborectalis muscle was absent from the first visit. The urethra was oval with an anteroposterior outer diameter of 10 mm and a transverse outer diameter of 13 mm before treatment. However, after three years of treatment, both anteroposterior and transverse diameters became circular, measuring 11 mm. Vaginal wall thickness increased from 8 to 12 mm at the center of the height of the urethra, making it possible to support the urethra, and pretreated adipose tissue space between the urethra and vagina disappeared. It was noted that the uneven and fragile urethra/vagina, the presence of adipose tissue space, and the absence of the left puborectalis muscle may have been the cause of the SUI. One year of VEL + UEL treatment resulted in long-term improvement of SUI; MRI showed changes in the urethra and vagina.

Occupational risk factors associated with lower urinary tract symptoms among female workers: a systematic review

A systematic review was performed aiming to identify the various occupational risk factors of lower urinary tract symptoms (LUTS) among female workers. A systematic, comprehensive literature search of PubMed, Embase and Cochrane Library databases was conducted to identify studies published until 24 November 2021, evaluating the possible occupational risk factors of LUTS among female workers. Two reviewers assessed all articles retrieved through a computerised search for eligibility using predetermined criteria. Data on the first author, publication year, country, study design, participants, identified occupational risk factors, outcome variables and main results were extracted from the selected articles. The Newcastle-Ottawa Quality Assessment Scale guidelines were adopted to estimate the quality scores. Overall, our search yielded a total of 16 articles suitable for review. The occupational risk factors identified in the studies were strenuous physical demand and activity, prolonged sitting, occupational stress, shift work, limited use of the toilet at work and other occupational environments (eg, an unclean and uncomfortable workplace, dangerous job and probability of accidents, feeling pressed for time and awkward position for long periods). The findings of this review may raise awareness regarding the risk of LUTS among female workers with these factors. From an occupational health perspective, the implementation of tailored prevention strategies based on these occupational factors may prevent female workers from developing LUTS.PROSPERO registration numberCRD42022316728.

Urinary Incontinence in Elite Female Athletes

PURPOSE OF REVIEW

To summarize the current understanding on the epidemiology, pathophysiology, and management strategies of urinary incontinence (UI) in female athletes, highlighting findings specific to nulliparous elite athletes.

RECENT FINDINGS

UI occurs in about 20-50% of female athletes of all ages and parity status, around 40% for younger nulliparous athletes, and is more prevalent in high-impact sports. Possible contributing factors to UI in female elite athletes include pelvic floor laxity and bladder neck descent, pelvic floor muscle fatigue, low energy availability, and hypermobility syndrome. In female elite athletes, urinary symptoms negatively affect quality of life, although the effects of symptoms on exercise participation are not well understood. Current management strategies are primarily conservative and centered on behavioral modifications and pelvic floor muscle physiotherapy. UI in female elite athletes appears to be multifactorial. Clarifying how individual factors influence UI in this population will inform athlete counseling, prevention, and treatment strategies.

The "Mother Load" and Return to Sport: A Case Report of Returning to Professional Netball Following Cesarean Section

Background

Increasing numbers of elite female athletes are competing in professional sport, and many wish to become pregnant and return to competitive sport after childbirth. Athletes have a higher risk of pelvic floor dysfunction (PFD) than non-athletes (54% versus 7%) and there is also an increased prevalence in post-partum women compared to nulliparous women (35% versus 2.8-7.9%). Additionally, PFD has been shown to influence athletic performance. High quality evidence for elite athletes is lacking, and there are no exercise guidelines specifically for these women to prepare or effectively guide their safe return to sport (RTS). The purpose of this case report is to detail the management of an elite athlete who presented following cesarean section (CS) with the goal of RTS within 16 weeks.

Case Description

A 27-year-old primiparous Caucasian professional netballer presented at four weeks post- caesarean section (CS) for RTS screening and assessment of pelvic floor muscle (PFM) function. Assessment included readiness and fear of movement screening, dynamic pelvic floor muscle function, structural integrity of the CS wound, levator hiatal dimensions, bladder neck descent, and early global neuromuscular screening. Measures were collected at four weeks, eight weeks, and six months post-partum. The post-partum athlete demonstrated alterations in pelvic floor muscle function, reduced lower limb power and psychological readiness. A functionally staged dynamic and sport specific pelvic floor muscle training program was implemented and adapted to the patient for her early post-partum timeline.

Results

Rehabilitation strategies were effective in achieving the primary outcome of RTS at 16 weeks post-partum with no adverse events reported at 6 months follow-up.

Discussion

This case highlights the need for a holistic and individualised RTS management approach that includes women's and pelvic health risk factors in a professional athlete.

Urinary Incontinence in Competitive Women Weightlifters

ABSTRACT

Wikander, L, Kirshbaum, MN, Waheed, N, and Gahreman, DE. Urinary incontinence in competitive women weightlifters. J Strength Cond Res 36(11): 3130-3135, 2022-Urinary incontinence has the potential to diminish athletic performance and discourage women from participating in sport and exercise. This study determined the prevalence and possible risk factors for urinary incontinence in competitive women weightlifters. This research was a cross-sectional, survey-based study completed by 191 competitive women weightlifters. The frequency and severity of urinary incontinence was determined using the Incontinence Severity Index. Urinary incontinence was defined as an Incontinence Severity Index score >0. The survey questions focused on risk factors, the context and triggers for urinary incontinence, and self-care strategies. Approximately, 31.9% of subjects experienced urinary incontinence within 3 months of completing the survey. Incontinence Severity Index scores were significantly correlated with parity ( r = 0.283, p = 0.01) and age ( r = 0.216, p = 0.01). There was no significant correlation between the Incontinence Severity Index score and the number of years participating in any form of resistance training ( r = -0.010, p = 0.886) or weightlifting ( r = -0.045, p = 0.534), body mass index ( r = 0.058, p = 0.422), or competition total ( r = -0.114, p = 0.115). The squat was the most likely exercise to provoke urinary incontinence. Although the number of repetitions, weight lifted, body position, and ground impact may increase the likelihood of urinary incontinence occurring during a lift, it is difficult to determine which factor has the greatest influence. Some self-care strategies used by competitive women weightlifters who experience urinary incontinence, such as training while dehydrated, have the potential to diminish athletic performance.

Comparison of First Childbirth Characteristics between Elite Judo Athletes and Non-Athletes: The Preliminary Retrospective Case-Control Study

It has been speculated that elite athletes are more likely to have obstetric interventions during labor and delivery. So far, the impact of many years of competitive sports participation on childbirth characteristics has not been well-established. This preliminary retrospective case-control study aimed to determine whether the first labors of elite judo competitors required obstetric interventions more frequently and were longer than those of non-athletes. The study comprised 32 parous women: 16 elite judo athletes and 16 non-athletes. Women were included if they had access to the following obstetric data (from their first childbirth hospital discharge reports and/or first child's health record books): induction and augmentation of labor, mode of delivery, the duration of labor and its second stage, episiotomy, perineal tear, and the neonate's Apgar score. Electronic surveys were completed concerning childbirth characteristics, level of "eliteness" (judo athletes), and recreational physical activity (non-athletes). The statistical analysis showed no significant between-group differences in any of the first childbirth outcomes under analysis. The preliminary results indicate elite judo practice before first pregnancy had no negative impact on the rates of labor induction and augmentation, delivery mode, duration of labor, the rates of episiotomy and perineal tear, and the neonate's Apgar score. Due to the small sample size, the conclusions should be considered with caution.

Effect of exercise on female pelvic floor morphology and muscle function: a systematic review

INTRODUCTION AND HYPOTHESIS

The objective was to synthesize the scientific evidence on the relationship of exercise with morphology and muscle function parameters of the female pelvic floor. The design was a systematic review.

METHODS

Searches were performed in MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, SportDiscuss, and Google Scholar up to April 2021. Observational and experimental studies evaluating the morphology and/or function of the pelvic floor muscles (PFMs) in women were eligible. Studies reporting exercise or sports disciplines as exposure/intervention were included.

RESULTS

Twenty-five studies were included. Compared with the control group, women performing vigorous and high-impact exercises exhibited lower maximum voluntary contraction of the PFM and those performing moderate exercise had better maximum voluntary contraction. Exercise practitioners had a larger hiatal area at rest, during contraction, and during Valsalva, and greater bladder neck descent than the control group.

CONCLUSIONS

The results of this review demonstrate an inverse relationship of PFM maximum voluntary contraction with exercise intensity. Qualitative synthesis showed that the studies found favorable outcomes for the control group in terms of hiatal area during contraction and Valsalva and bladder neck displacement.

Sports Obstetrics: Implications of Pregnancy in Elite Sportswomen, a Narrative Review

Increasing numbers of females are participating in elite sports, with a record number having competed at the Tokyo Olympic Games. Importantly, the ages of peak performance and fertility are very likely to coincide; as such, it is inevitable that pregnancy will occur during training and competition. Whilst there is considerable evidence to promote regular exercise in pregnancy, with benefits including a reduction in hypertensive disorders, gestational diabetes, and reduced rates of post-natal depression, few studies have been conducted which include elite athletes. Indeed, there are concerns that high-intensity exercise may lead to increased rates of miscarriage and preterm labour, amongst other pregnancy-related complications. There is minimal guidance on the obstetric management of athletes, and consequently, healthcare professionals frequently adopt a very conservative approach to managing such people. This narrative review summarises the evidence on the antenatal, intrapartum, and postpartum outcomes in elite athletes and provides recommendations for healthcare providers, demonstrating that generally, pregnant athletes can continue their training, with a few notable exceptions. It also summarises the physiological changes that occur in pregnancy and reviews the literature base regarding how these changes may impact performance, with benefits arising from pregnancy-associated cardiovascular adaptations at earlier gestations but later changes causing an increased risk of injury and fatigue.

Stress Urinary Incontinence Among Young Nulliparous Female Athletes

Urinary incontinence (UI) is described as unintentional voiding of urine that is usually seen in post-partum and post-menopausal women due to the weakening of pelvic floor muscles (PFM). Recent studies have shown an increase in the prevalence of stress urinary incontinence (SUI) among young nulliparous female athletes. The association between UI and high-impact physical activity is due to increased intra-abdominal pressure during high-impact sports exceeding intra-urethral pressure. Usually, the levator ani muscle (LAM) helps in urethral closure. However, weakening or injury of LAM can reduce the pelvic support and cause UI in young female athletes. This study aims to assess the prevalence of SUI among young nulliparous athletes and also explore the association between SUI and athletic sports in young females. We searched PubMed and Google Scholar as databases to find specific articles about the topic. After the inclusion and exclusion criteria were applied, 52 articles were selected for this review. It is found that there is an increased UI prevalence, mainly SUI, among young nulliparous female athletes, especially in volleyball players and long-distance runners. Nulliparous athletes involved in high-impact exercises were found to have an increased cross-sectional area of LAM and puborectalis muscle width. SUI is usually under-reported and underdiagnosed due to lack of knowledge and unawareness, which can negatively affect the personal and social life of young females. PFM training is considered the first line of therapy among nulliparous athletes. However, it is unclear whether the high-impact effects of sports cause UI through PFM fatigue or PFM damage. More research is needed to better understand this effect.

The Association of Physical Activity and Urinary Incontinence in US Women: Results from a Multi-Year National Survey

OBJECTIVES

To evaluate the relationships between physical activity, both work and recreational, and urinary incontinence among women.

METHODS

We assessed women aged 20 years and older in 2008-2018 NHANES (National Health and Nutrition Examination Survey) cycles who answered self-reported urinary incontinence and physical activity questions. Weighted, multivariate logistic regression model was used to determine the association between incontinence and physical activity levels after adjusting for age, body mass index, diabetes, race, parity, menopause and smoking.

RESULTS

A total of 30,213 women were included in analysis, of whom 23.15% had stress incontinence, 23.16% had urge incontinence, and 8.42% had mixed incontinence (answered "yes" to both stress and urge incontinence). Women who engaged in moderate recreational activity were less likely to report stress and urge incontinence (OR 0.79, 95% CI 0.62-0.99 and OR 0.66, 95% CI 0.48-0.90, respectively). Similarly, women who engaged in moderate activity work were less likely to report stress, urge and mixed incontinence (OR 0.84, 95% CI 0.70-0.99; OR 0.84, 95% CI 0.72-0.99; and OR 0.66 95% CI 0.45-0.97, respectively).

CONCLUSIONS

Moderate physical activity and greater time spent participating in moderate physical activity are associated with a decreased likelihood of stress, urge and mixed incontinence in women. This relationship holds for both recreational and work-related activity. We hypothesize that the mechanism of this relationship is multifactorial, with moderate physical activity improving pelvic floor strength and modifying neurophysiological mediators (such as stress) involved in the pathogenesis of incontinence.

Pelvic floor evaluation in CrossFit® athletes and urinary incontinence: a cross-sectional observational study

Athletic urinary incontinence is characterized by urinary loss during sports practice. This condition occurs in the case of CrossFit®, a modality based on high intensity training and functional movements, it can also be considered as having a high impact on the pelvic floor. This study aimed to compare the force and the contraction capacity of the pelvic floor musculature and urinary incontinence between female CrossFit® practitioners (AG) and non-practitioners (CG). We performed a cross-sectional observational study in the period from December 2018 and May 2019. Complaints of urinary incontinence was assessed by the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF); the functional evaluation of the pelvic floor was performed by digital palpation; resting tone, maximum voluntary contraction, fast contractions and sustained contraction of the pelvic floor muscles was tested by electromyography. The prevalence of urinary incontinence was significantly higher in AG compared with CG (p < .001). Nevertheless, we did not find significant differences between the two groups for functional assessment and electromyographic parameters. The AG presented a prevalence 60% of UI, while CG only 9,5 (p < 0,001). Considering this point, tailored prevention strategies seem mandatory in this population, in order to allow early identification and management of urinary incontinence.

The Prevalence of Urinary Incontinence among Adolescent Female Athletes: A Systematic Review

This review aimed to synthesize the most up-to-date evidence regarding the prevalence of urinary incontinence (UI) among adolescent female athletes. We conducted a systematic review of studies regarding UI in female athletes less than 19 years of age. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRIMSA). The electronic databases of PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and Web of Science (WOS) were searched between October and November 2020. After blinded peer evaluation, a total of 215 studies were identified and nine were included. Risk of bias was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. This review identified a prevalence of UI in adolescent female athletes between 18% to 80% with an average of 48.58%. The most prevalent sports were trampolining followed by rope skipping. The prevalence of UI among adolescent female athletes practicing impact sports was significantly prevalent. There is a need for further research, education, and targeted interventions for adolescent female athletes with UI.

Prevalence of Female Urinary Incontinence in Crossfit Practitioners and Associated Factors: An Internet Population-Based Survey

OBJECTIVES

CrossFit comprises a set of high-intensity, high-impact exercises that includes movements that may increase intra-abdominal pressure and cause involuntary loss of urine. There is scant literature about the prevalence of urinary incontinence (UI) in female crossfitters, as well as its associated factors.

METHODS

A population-based Internet survey stored in a website created with information on the benefits and risks of CrossFit for women's health (https://crosscontinencebr.wixsite.com/crosscontinencebr) invited female crossfitters. In total, 551 women answered an online questionnaire, and the demographic variables (age, marital status, and parity), anthropometric data (weight, height, and body mass index), and the presence of UI during exercises were also investigated. The prevalence of UI and its associated factors were calculated using a logistic regression model. The significance level was set at 5%.

RESULTS

The overall prevalence of UI during CrossFit exercises was 29.95%, and most women with UI reported loss of urine during at least one exercise (16.70%). Women with UI were older (33.77 ± 8.03 years) than those without UI (30.63 ± 6.93 years; P < 0.001). Double under (20.15%) and single under (7.99%) were the exercises that were most frequently associated with UI and also the only variables that remained in the final model that caused UI. The duration of CrossFit practice, number of days per week practicing CrossFit, daily time practice, previous vaginal delivery, and mean birth weight were not statistically associated with UI.

CONCLUSIONS

One-third of female crossfitters presented with UI during exercise. Double under was the exercise that was the most associated with UI.

Benefits of Physiotherapy on Urinary Incontinence in High-Performance Female Athletes. Meta-Analysis

Introduction: High performance female athletes may be a risk group for the development of urinary incontinence due to the imbalance of forces between the abdomen and the pelvis. Pelvic floor physiotherapy may be a useful treatment in these patients. Objectives: (1) To identify the scientific evidence for pelvic floor (PF) dysfunctions that are associated with urinary incontinence (UI) in high-performance sportswomen. (2) To determine whether pelvic floor physiotherapy (PT) corrects UI in elite female athletes. Materials and methods: Meta-analysis of published scientific evidence. The articles analyzed were found through the following search terms: (A) pelvic floor dysfunction elite female athletes; (B) urinary incontinence elite female athletes; (C) pelvic floor dysfunction elite female athletes physiotherapy; (D) urinary incontinence elite female athletes physiotherapy. Variables studied: type of study, number of individuals, age, prevalence of urinary incontinence described in the athletes, type of sport, type of UI, aspect investigated in the articles (prevalence, response to treatment, etiopathogenesis, response to PT treatment, concomitant health conditions or diseases. Study groups according to the impact of each sport on the PF: G1: low-impact (noncompetitive sports, golf, swimming, running athletics, throwing athletics); G2: moderate impact (cross-country skiing, field hockey, tennis, badminton, baseball) and G3: high impact (gymnastics, artistic gymnastics, rhythmic gymnastics, ballet, aerobics, jump sports (high, long, triple and pole jump)), judo, soccer, basketball, handball, volleyball). Descriptive analysis, ANOVA and meta-analysis. Results: Mean age 22.69 years (SD 2.70, 18.00–29.49), with no difference between athletes and controls. Average number of athletes for each study was 284.38 (SD 373,867, 1–1263). The most frequent type of study was case-control (39.60%), followed by cross-sectional (30.20%). The type of UI was most often unspecified by the study (47.20%), was stress UI (SUI, 24.50%), or was referred to as general UI (18.90%). Studies on prevalence were more frequent (54.70%), followed by etiopathogenesis (28.30%) and, lastly, on treatment (17.00%). In most cases sportswomen did not have any disease or concomitant pathological condition (77.40%). More general UI was found in G1 (36.40%), SUI in G2 (50%) and unspecified UI in G3 (63.64%). In the meta-analysis, elite athletes were found to suffer more UI than the control women. In elite female athletes, in general, physiotherapy contributed to gain in urinary continence more than in control women (risk ratio 0.81, confidence interval 0.78–0.84)). In elite female athletes, former elite female athletes and in pregnant women who regularly engage in aerobic activity, physiotherapy was successful in delivering superior urinary continence compared to the control group. The risk of UI was the same in athletes and in the control group in volleyball female athletes, elite female athletes, cross-country skiers and runners. Treatment with PT was more effective in control women than in gymnastics, basketball, tennis, field hockey, track, swimming, volleyball, softball, golf, soccer and elite female athletes. Conclusions: There is pelvic floor dysfunction in high-performance athletes associated with athletic activity and urinary incontinence. Eating disorders, constipation, family history of urinary incontinence, history of urinary tract infections and decreased flexibility of the plantar arch are associated with an increased risk of UI in elite female athletes. Pelvic floor physiotherapy as a treatment for urinary incontinence in elite female athletes, former elite female athletes and pregnant athletes who engage in regular aerobic activity leads to a higher continence gain than that obtained by nonathlete women.

Change in levator ani muscle stiffness and active force during pregnancy and post-partum

INTRODUCTION AND HYPOTHESIS

It is assumed changes occur to the biomechanics and viscoelastic response of the levator ani muscle during pregnancy; however, there is limited evidence of this. This study used instrumentation and clinical measures to determine the stiffness and active force capacity of levator ani muscle during pregnancy and post-partum, investigated any associations with delivery outcomes, and explored the biomechanical properties associated with symptoms of pelvic floor dysfunction.

METHODS

This was a prospective observational study, with nulliparous women with a singleton low-risk pregnancy. Data were collected at two stages during pregnancy and post-partum. Measurements included the Australian Pelvic Floor Questionnaire, palpation of active force, and elastometry measurements. Post-partum, 3D/4D ultrasound measurements were included. Repeated measures ANOVAs, pairwise comparisons, Pearson correlation coefficients, and Student's t-tests were used as appropriate.

RESULTS

Fifty-nine women took part in the study. Active force was significantly different over the pregnancy and post-partum, measured with instrumentation (p = 0.002) and palpation (p = 0.006 right, p = 0.029 left). There was no significant change in muscle stiffness during pregnancy. Post-partum muscle stiffness was significantly different between women who gave birth vaginally vs. caesarean section (p = 0.002). Post-partum there were differences in levator hiatal area, symptoms of bladder dysfunction, prolapse symptoms, and sexual dysfunction symptoms.

CONCLUSIONS

Active force of the levator ani muscle was significantly reduced during pregnancy and in the post-partum period, while muscle stiffness reduced only in those who had vaginal deliveries.

Prevalence of Urinary Incontinence in High-Impact Sport Athletes: A Systematic Review and Meta-Analysis

The aim of this study was to systematize the scientific evidence that assessed the prevalence of urinary incontinence in female athletes and determine which modality is most predisposed to stress urinary incontinence. From September to December 2018, a systematic literature search of current interventional studies of stress urinary incontinence of the last ten years was performed using PubMed, EMBASE, Scopus and Web of Science databases. The methodological quality was assessed by the Downs and Black scale, while the data collected from the studies were analyzed through meta-analysis. Nine studies met the eligibility criteria, meaning they included reports of urinary incontinence in different sports. The meta-analysis showed 25.9% prevalence of urinary incontinence in female athletes in different sports, as well as 20.7% prevalence of stress urinary incontinence. The most prevalent high impact sport was volleyball, with the value of 75.6%. The prevalence of urinary incontinence can be high in female athletes, with high-impact sports potentially increasing the risk for stress urinary incontinence. Further research is needed regarding the potential risk factors related to the onset of urinary incontinence.

Game therapy a new approach to treat women facing mixed urinary incontinence: A study protocol

AIMS

To describe a pelvic floor muscle training (PFMT) isolated and associated with game therapy (PFMT + GT) for women facing mixed urinary incontinence (MUI) during climacteric period.

METHODS

To standardize a randomized controlled clinical trial intervention, a protocol was created, in an attempt to decrease women's symptomatology generated by MUI, through pelvic floor and abdomino-loin-pelvic muscles strength, and endurance. This study protocol will be composed of 32 volunteers, divided into two groups of 16. They will perform PFMT isolated or PFMT + GT, twice a week during 8 weeks. Interventions will last 40 minutes and will be divided into warming (5 minutes), training (30 minutes), and 5 minutes will be composed of resting time between exercises (1 minute each). Isolated PFMT sessions will be performed through four modalities of exercises: diaphragmatic, bridge, abdominal (plank), and pelvic mobility. PFMT + GT training will be carried out by using Wii Fit Plus games, such as Lotus Focus, Penguin Slide, Basic Step, and Hula Hoop from Wii equipment. Assessments will occur before, after, and 1 month after interventions. Vaginal manometry, 1-hour Pad Test, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and Patient Global Intervention (PGI) will be used to evaluate the sample.

CONCLUSIONS

It is expected greater increase on pelvic floor muscle (PFM) strength, endurance, vaginal pressure for PFMT + GG. Moreover, it is supposed that PFMT + GT volunteers present better treatment adherence due to games motivational inclusion.

Assessment of pelvic floor muscles in sportswomen: Quality of life and related factors

OBJECTIVES

To evaluate Maximum Voluntary Contraction (MVC) of the Pelvic Floor Muscles (PFM) in sportswomen, to observe the urinary symptoms and their impact on the Quality of Life (QoL).

DESIGN

Observational cross-sectional study.

SETTING

Gyms and teams in the North of Portugal.

PARTICIPANTS

Sportswomen (n = 197).

MAIN OUTCOME MEASURES

The measurement was performed using a manometer. The sportswomen were instructed to perform 3 MVC of the perineum, held for 3 s. The Kings Health Questionnaire (KHQ) was used to evaluate urinary symptoms and the QoL of the sportswomen.

RESULTS

Age significantly influenced (p < 0.05) the QoL in all domains. An increase in BMI was also significantly associated with a decrease in the QoL. MVC values had a highly significant effect on the overall QoL and all domains, including a reduction in urinary symptoms. The weekly time of physical activity was associated with a better QoL in symptomatology. The practice of high-impact activities decreased the QoL (compared to low-impact activities). The vaginal resting pressure values ranged from 1.60 to 59.80 (24.34 ± 11.00).

CONCLUSIONS

Age, BMI and high-impact sports appear to be the leading factors that promote the onset of SUI, which in turn decrease the QoL in sportswomen. There was a positive association between MVC and weekly time of physical activity in the QoL.

Is Physical Activity Good or Bad for the Female Pelvic Floor? A Narrative Review

More women participate in sports than ever before and the proportion of women athletes at the Olympic Games is nearly 50%. The pelvic floor in women may be the only area of the body where the positive effect of physical activity has been questioned. The aim of this narrative review is to present two widely held opposing hypotheses on the effect of general exercise on the pelvic floor and to discuss the evidence for each. Hypothesis 1: by strengthening the pelvic floor muscles (PFM) and decreasing the levator hiatus, exercise decreases the risk of urinary incontinence, anal incontinence and pelvic organ prolapse, but negatively affects the ease and safety of childbirth. Hypothesis 2: by overloading and stretching the PFM, exercise not only increases the risk of these disorders, but also makes labor and childbirth easier, as the PFM do not obstruct the exit of the fetus. Key findings of this review endorse aspects of both hypotheses. Exercising women generally have similar or stronger PFM strength and larger levator ani muscles than non-exercising women, but this does not seem to have a greater risk of obstructed labor or childbirth. Additionally, women that specifically train their PFM while pregnant are not more likely to have outcomes associated with obstructed labor. Mild-to-moderate physical activity, such as walking, decreases the risk of urinary incontinence but female athletes are about three times more likely to have urinary incontinence compared to controls. There is some evidence that strenuous exercise may cause and worsen pelvic organ prolapse, but data are inconsistent. Both intra-abdominal pressure associated with exercise and PFM strength vary between activities and between women; thus the threshold for optimal or negative effects on the pelvic floor almost certainly differs from person to person. Our review highlights many knowledge gaps that need to be understood to understand the full effects of strenuous and non-strenuous activities on pelvic floor health.

Elite athletes get pregnant, have healthy babies and return to sport early postpartum

Objectives

To enhance knowledge on pregnancy and return to sport in the postpartum period in elite female athletes.

Methods

34 Norwegian elite athletes (33.1 years) and 34 active controls (31.5 years) were asked about training and competitive history, pregnancy-related issues, injuries, body dissatisfaction (BD), drive for thinness (DT), eating disorders (ED) and practical experiences, through a questionnaire and interview. Independent samples T-tests or χ² tests for between-group differences and paired-samples T-tests and repeated measures analysis of variance for within group differences were used.

Results

No group differences in fertility problems, miscarriage, preterm birth or low birth weight were found. Both groups decreased training volume all trimesters and the first two postpartum periods compared with prepregnancy, and more athletes returned to sport/exercise at week 0–6 postpartum. We found no group differences in complications during pregnancy and delivery, but athletes reported fewer common complaints. Four athletes experienced stress fracture postpartum. Athletes had higher BD and DT postpartum, while controls reduced DT score. Number of athletes with clinical ED was reduced postpartum, while constant in controls. Athletes were not satisfied with advice related to strength training and nutrition during pregnancy.

Conclusion

Elite athletes and active controls get pregnant easily, deliver healthy babies and decrease training during pregnancy and the first postpartum periods compared with prepregnancy. Most athletes and every third control returned to sport or exercise at week 0–6 postpartum. Athletes report stress fractures and increased BD and DT, but decreased ED postpartum. However, since relatively few athletes were included these findings need further investigation.

Prevalence of urinary incontinence in women powerlifters: a pilot study

INTRODUCTION AND HYPOTHESIS

Increased intra-abdominal pressure is associated with urinary incontinence (UI) as is increasing age, obesity, and participating in sport at an elite level. We aimed to determine the prevalence of UI in competitive women powerlifters and establish if commonly cited risk factors affect the incidence of UI.

METHODS

The authors developed a 17-item questionnaire to investigate the prevalence of UI and the relationship of UI with age, body mass, resistance training experience, and competition grade in competitive women powerlifters. The questionnaire was distributed through three major powerlifting federations in Australia for 16 months. The data of 134 competitive women powerlifters were collected anonymously using Qualtrics, and were analysed using multivariate analysis.

RESULTS

In combination, the age of lifters, resistance training experience, body weight categories, and competition grade accounted for a significant 28% of the variability in the Incontinence Severity Index (ISI) (p < 0.01). However, the ISI was not significantly different among age groups, body weight categories, or competition grade. Approximately, 41% of women powerlifters had experienced UI at some stage in life, and 37% of women powerlifters currently experienced UI during training, competition, or maximum effort lifts. However, the rate of UI experienced during daily life activities was approximately 11%.

CONCLUSIONS

This study showed that competitive women powerlifters experience a higher rate of UI during lifting-related activities than in daily life and that the rate of UI correlates positively with age, body weight categories, resistance training experience, and competition grade.

The effect of high impact crossfit exercises on stress urinary incontinence in physically active women

AIMS

The impact of CrossFit (high energy and intensity exercise) on SUI has not been well described. This study evaluates the incidence of SUI in physically active women, and examines specific exercises that can increase SUI.

METHODS

A cross-sectional study was conducted in women from four CrossFit centers and one aerobic center for comparison. Participants were surveyed regarding baseline demographics, activity levels, severity, and frequency of leakage during CrossFit exercises as well as preventative strategies against SUI. Participants were stratified based on age, body mass index, types of exercises, parity, delivery, and compared using Mann Whitney-U and Chi square.

RESULTS

This study had 105 CrossFit (mean = 36.9 years) and 44 aerobic (mean = 29.0 years) participants. Fifty women reported SUI during exercises, while none of the aerobic women reported SUI during exercise. The top three CrossFit exercises associated to SUI were double-unders (47.7%), jumping rope (41.3%), and box jumps (28.4%). CrossFit women with a history of parity had significantly more episodes of SUI with box jumps, jumping rope, double-unders, thrusters, squats without weights, squats with weights, and trampoline jumping (P < 0.001). The top preventative strategies were emptying the bladder before workouts, wearing dark pants, and performing Kegel exercises during workout. Vaginal delivery (OR 4.94) and total incontinence symptom severity index (OR 1.45) were both significant predictors of SUI during exercise (P < 0.05).

CONCLUSION

There is a significantly higher risk of SUI during CrossFit exercises associated with previous pregnancy and vaginal delivery but also in nulliparous women. In general, women participating in CrossFit have been applying preventative measures for protection of SUI during exercises.

Terminology of Pelvic Floor Muscle Function in Women With and Without Urinary Incontinence: A Systematic Review

BACKGROUND

Pelvic floor muscle function (PFMF) is a target of the physical therapist intervention for women with urinary incontinence (UI). However, possible variations in PFMF terminology might hamper communication among researchers and health care professionals in Women's Health.

OBJECTIVE

The objective of this study was to investigate the terminology of PFMF regarding clear terms, conceptual definitions, and operational definitions.

DATA SOURCES

Data sources include PUBMED, CINAHL, LILACS, and SCIELO.

STUDY SELECTION

Observational studies investigating any PFMF in women with or without UI, published in English, Spanish, or Portuguese from 2005 through 2017, were considered.

DATA EXTRACTION

The risk of bias was assessed by a questionnaire on the quality of observational studies. Data on terminology were extracted as terms, conceptual definitions, and operational definitions of PFMF and were synthesized according to key words, key ideas, and key operationalization, respectively. Consistencies and variations were identified for the most frequently investigated PFMF.

DATA SYNTHESIS

Sixty-four studies were included, and a low risk of bias was identified. All studies presented terms and operational definitions of PFMF, but only 29.7% presented conceptual definitions of those terms. One hundred ninety-six different terms referred to PFMF. According to similarities in terminology, 161 PFMF terms could be grouped under 26 terms; the other 35 were left ungrouped. Therefore, a total of 61 different PFMF terms were identified in the literature.

LIMITATIONS

A limitation in the study was that only observational studies were included.

CONCLUSIONS

A large variation in PFMF terminology was identified, precluding data gathering and meta-analysis. The lack of use of standardized terminology delays the progress of scientific knowledge and evidence-based practice dissemination. Efforts toward creating a collaborative, consensual terminology based on a sound framework are necessary.

Do female elite athletes experience more complicated childbirth than non-athletes? A case-control study

OBJECTIVE

Previous studies have suggested that female athletes might be at higher risk of experiencing complications such as caesarean sections and perineal tears during labour than non-athletes. Our aim was to study delivery outcomes, including emergency caesarean section rates, length of the first and second stages of labour and severe perineal tears, in first-time pregnant elite athletes compared with non-athletes.

METHODS

This is a retrospective case-control study comparing birth outcomes of primiparous female elite athletes engaging in high-impact and low-impact sports compared with non-athletic controls. The athletes had prior to birth competed at a national team level or equivalent. Participant characteristics and frequency of training for at least 3 years before a first pregnancy were collected via a self-administered questionnaire. Information on delivery outcome was retrieved from the Icelandic Medical Birth Registry.

RESULTS

In total, 248 participated, 118 controls, 41 low-impact and 89 high-impact elite athletes. No significant differences were found between the groups with regard to incidence of emergency caesarean section or length of the first and second stages of labour. The incidence of third-degree to fourth-degree perineal tears was significantly higher (23.7%) among low-impact athletes than in the high-impact group (5.1%, p=0.01), but no significant differences were seen when the athletes were compared with the controls (12%; p=0.09 for low-impact and p=0.12 for high-impact athletes).

CONCLUSION

Participation in competitive sports at the elite level was not related to adverse delivery outcome, including length of labour, the need for caesarean section during delivery and severe perineal tears.

Role of chronic exercise on pelvic floor support and function

PURPOSE OF REVIEW

To summarize recent literature about the potential role of chronic exercise on pelvic floor support and function.

RECENT FINDINGS

Stress urinary incontinence is common during physical activity. Scant evidence suggests a dose-response association between higher volumes of exercise and urinary incontinence. Athletes do not appear to have greater pelvic floor muscle strength or worse pelvic floor support compared to nonathletes. Pelvic floor muscle electromyographic activity increases substantially as running speeds increase.

SUMMARY

Based on the current literature, no strong conclusions can be drawn about whether chronic exercise exerts a positive or negative influence on pelvic floor support and function. Adopting longitudinal research methodology that prospectively monitors exercise exposure and subsequent changes in pelvic floor support and function would help to reduce selection bias associated with cross sectional studies on groups of athletes.

EAU Guidelines on Assessment and Nonsurgical Management of Urinary Incontinence

CONTEXT

The European Association of Urology guidelines on urinary incontinence (UI) have been updated in cyclical fashion with successive major chapters being revised each year. The sections on assessment, diagnosis, and nonsurgical treatment have been updated as of mid-2016.

OBJECTIVE

We present a condensed version of the full guideline on assessment and nonsurgical management of UI, with the aim of improving accessibility and increasing their dissemination.

EVIDENCE ACQUISITION

Our literature search was updated from the previous cut-off of July 2010 up to April 2016. Evidence synthesis was carried out by a pragmatic review of current systematic reviews and any newer subsequent high-quality studies, based on Population, Interevention, Comparator, and Outcome questions. Appraisal was conducted by an international panel of experts, working on a strictly nonprofit and voluntary basis, to develop concise evidence statements and action-based recommendations using modified Oxford and GRADE criteria.

EVIDENCE SYNTHESIS

The guidelines include algorithms that summarise the suggested pathway for standard, uncomplicated patients with UI and are more useable in daily practice. The full version of the guideline is available at http://uroweb.org/guideline/urinary-incontinence/.

CONCLUSIONS

These updated guidelines provide an evidence-based summary of the assessment and nonsurgical management of UI, together with a clear clinical algorithm and action-based recommendations. Although these guidelines are applicable to a standard patient, it must be remembered that therapy should always be tailored to individual patients' needs and circumstances.

PATIENT SUMMARY

Urinary incontinence is a very common condition which negatively impacts patient's quality of life. Several types of incontinence exist and since the treatments will vary, it is important that the diagnostic evaluation establishes which type is present. The diagnosis should also identify patients who need rapid referral to an appropriate specialist. These guidelines aim to provide sensible and practical evidence-based guidance on the clinical problem of urinary incontinence.

Occurrence Rates and Predictors of Lower Urinary Tract Symptoms and Incontinence in Female Athletes

Introduction and hypothesis

To assess the prevalence of lower urinary tract symptoms (LUTS) and incontinence in female athletes and to determine the etiological factors.

Methods

An anonymous self-questionnaire was collected from 623 casual female athletes aged 18 to 56 years, who were involved in 12 different sports. The surveys were distributed by hand to the athletes, during their sports fitness tests, in a sports center. We investigated the relationship between urinary disorders and factors such as age, body mass index (BMI), parity, duration of physical exercise, and type of sport.

Results

The prevalence of LUTS was 54.7%, and 30% for urinary incontinence. Changes in urinary frequency were detected in 91 (14.6%) women. Prevalence of dysuria was 13.3%, urinary straining was present in 173 (27.8%) athletes, whereas urinary urgency had an estimated prevalence of 37.2% with 232 athletes suffering from this disorder. Urgency was very common in volleyball players, as was dysuria among hockey and basketball players, whereas straining mainly affected aerobic participants and cyclists. Long training hours and competitive practices were correlated with the onset of LUTS. High-impact sports were more frequently associated with incontinence, while low-impact sports with LUTS. The sport with the main number of incontinent people was football. Urge incontinence affected a lot of athletes, mainly cyclists and football players. Stress incontinence was more frequent in hockey and volleyball players.

Conclusions

LUTS and incontinence are prevalent in female athletes. In many cases, the disorders were present only during sports activities. In this sample, the presence of urinary disorders did not seem to be a barrier during sports or exercise.

Pelvic floor muscle function and urinary incontinence in the female athlete

Urinary incontinence, defined as involuntary leakage of urine, is often considered a disorder of post-partum and post-menopausal women. However, this disorder is not exclusive to older women, as recent research has demonstrated a high prevalence of urinary incontinence among young, nulliparous female athletes. In fact, females participating in repetitive, high-impact sports are at the highest risk for urinary incontinence. In these athletes, the absence of sufficient pelvic floor strength and coordination to withstand sport related increases in intra-abdominal pressure results in physical activity related urinary incontinence, and may be a predictor of urinary incontinence in later adulthood. Pelvic floor dysfunction and urinary incontinence in this population is under-reported and consequently under-diagnosed and under-treated. Therefore, the prevalence is higher than one might expect, and the effects can include decreased performance, change in sport and avoidance of physical activity all together. This manuscript highlights the prevalence of pelvic floor dysfunction and outlines its pathophysiology, diagnosis, treatment, and rehabilitation. We discuss how greater recognition of this disorder by health care providers and routinely querying active females is a critical step in addressing this issue. Identification, education and appropriate rehabilitation can positively affect outcomes in regards to urinary incontinence symptoms and maintain physical activity participation in these athletes.

Pelvic floor dynamics during high-impact athletic activities: A computational modeling study

BACKGROUND

Stress urinary incontinence is a significant problem in young female athletes, but the pathophysiology remains unclear because of the limited knowledge of the pelvic floor support function and limited capability of currently available assessment tools. The aim of our study is to develop an advanced computer modeling tool to better understand the dynamics of the internal pelvic floor during highly transient athletic activities.

METHODS

Apelvic model was developed based on high-resolution MRI scans of a healthy nulliparous young female. A jump-landing process was simulated using realistic boundary conditions captured from jumping experiments. Hypothesized alterations of the function of pelvic floor muscles were simulated by weakening or strengthening the levator ani muscle stiffness at different levels. Intra-abdominal pressures and corresponding deformations of pelvic floor structures were monitored at different levels of weakness or enhancement.

FINDINGS

Results show that pelvic floor deformations generated during a jump-landing process differed greatly from those seen in a Valsalva maneuver which is commonly used for diagnosis in clinic. The urethral mobility was only slightly influenced by the alterations of the levator ani muscle stiffness. Implications for risk factors and treatment strategies were also discussed.

INTERPRETATION

Results suggest that clinical diagnosis should make allowances for observed differences in pelvic floor deformations between a Valsalva maneuver and a jump-landing process to ensure accuracy. Urethral hypermobility may be a less contributing factor than the intrinsic sphincteric closure system to the incontinence of young female athletes.

Exercise and pregnancy in recreational and elite athletes: 2016 evidence summary from the IOC expert group meeting, Lausanne. Part 2-the effect of exercise on the fetus, labour and birth

This is Part 2 of 5 in the series of evidence statements from the IOC expert committee on exercise and pregnancy in recreational and elite athletes. Part 1 focused on the effects of training during pregnancy and on the management of common pregnancy-related symptoms experienced by athletes. In Part 2, we focus on maternal and fetal perinatal outcomes.

Antenatal pelvic floor biometry is related to levator ani muscle injury

OBJECTIVE

To evaluate the relationship between antenatal pelvic floor biometry and levator ani muscle (LAM) injury in Chinese women.

METHODS

Three-dimensional transperineal ultrasound was performed in nulliparous Chinese women with a singleton pregnancy at 9-12 weeks, 26-28 weeks and 36-38 weeks of gestation and again at 12 months after delivery. Hiatal anteroposterior (AP) diameter, transverse diameter and area were measured on the antenatal ultrasound volumes obtained at rest, on Valsalva maneuver and during pelvic floor muscle contraction (PFMC). LAM injury was evaluated using ultrasound volumes obtained during PFMC at 12 months after delivery.

RESULTS

In total, 328 women completed the study. At 12 months after delivery, 38 (14.8% of those who delivered vaginally) women had LAM injury; 28 were unilateral (14 right- and 14 left-sided) and 10 were bilateral. In all three trimesters there was smaller hiatal AP diameter and hiatal area in women with LAM injury when compared with women without injury. On multivariable analysis of the three factors, hiatal AP diameter at rest, hiatal area at rest and operative vaginal delivery, only hiatal AP diameter at rest in all three trimesters was an independent factor of LAM injury. A larger hiatal AP diameter at rest in the first, second and third trimesters reduced the likelihood of LAM injury with odds ratios of 0.21, 0.15 and 0.21, respectively.

CONCLUSIONS

A smaller antenatal hiatal AP diameter at rest is a risk factor for LAM injury. The hiatal AP diameter is relatively simple to measure and the error in measurement is relatively small. A prospective study to confirm this relationship and to explore whether this measurement, performed in the midsagittal plane, is repeatable should be performed. Copyright © 2015 ISUOG.

Health-related quality of life and mental health in older women with urinary incontinence

OBJECTIVES

The purpose of this cross-sectional study was to compare health-related quality of life (QOL) and mental health between older women with and without urinary incontinence.

METHOD

This study is a secondary data analysis using raw data from 1874 women aged 65 years or older who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) IV (2008-2009), a nationally representative sample.

RESULTS

In the pain/discomfort dimension of the EuroQol-5, 25.4% of the participants experienced urinary incontinence and 14.7% did not (p = .001). In the anxiety/depression dimension, urinary incontinence was present in 8.3% of the participants and absent in 3.6% (p = 0.012). In addition, the results of an ANCOVA showed that scores in both the EuroQol visual analogue scale and the EQ-5D index were significantly lower in participants with urinary incontinence relative to those without. The risk of stress and depression in older women with urinary incontinence was approximately 2 and 1.5 times higher, respectively, than that of participants without urinary incontinence.

CONCLUSION

Health-related QOL in older women with urinary incontinence was relatively low, while levels of stress and depression were high. Therefore, in order to improve QOL and mental health in older women, the understanding and management of urinary incontinence interventions is required.

Is pelvic organ support different between young nulliparous African and Caucasian women?

OBJECTIVE

There seems to be substantial variation in the prevalence of pelvic floor disorders between different ethnic groups. This may be due partially to differences in pelvic floor structure and functional anatomy. To date, data on this issue are sparse. The aim of this study was to compare hiatal dimensions, pelvic organ descent and levator biometry in young, healthy nulliparous Caucasian and African women.

METHODS

Healthy nulliparous non-pregnant volunteers attending a local nursing school in Uganda were invited to participate in this study during two fistula camps. All volunteers underwent a simple physician-administered questionnaire and a four-dimensional translabial ultrasound examination. Offline analysis was performed to assess hiatal dimensions, pelvic organ descent, levator muscle thickness and area. To compare findings with those obtained in nulliparous non-pregnant Caucasians, we retrieved the three-dimensional/four-dimensional ultrasound volume datasets of a previously published study.

RESULTS

The dataset of 76 Ugandan and 49 Caucasian women was analyzed. The two groups were not matched but they were comparable in age and body mass index. All measurements of hiatal dimensions and pelvic organ descent were significantly higher among the Ugandans (all P ≤ 0.01); however, muscle thickness and area were not significantly different between the two groups.

CONCLUSIONS

Substantial differences between Caucasian and Ugandan non-pregnant nulliparae were identified in this study comparing functional pelvic floor anatomy. It appears likely that these differences in functional anatomy are at least partly genetic in nature. Copyright © 2015 ISUOG. Published by John Wiley & Sons Ltd.

Effect of Spinal Manipulation on Pelvic Floor Functional Changes in Pregnant and Nonpregnant Women: A Preliminary Study

OBJECTIVE

The aim of this study was to investigate whether a single session of spinal manipulation of pregnant women can alter pelvic floor muscle function as measured using ultrasonographic imaging.

METHODS

In this preliminary, prospective, comparative study, transperineal ultrasonographic imaging was used to assess pelvic floor anatomy and function in 11 primigravid women in their second trimester recruited via notice boards at obstetric caregivers, pregnancy keep-fit classes, and word of mouth and 15 nulliparous women recruited from a convenience sample of female students at the New Zealand College of Chiropractic. Following bladder voiding, 3-/4-dimensional transperineal ultrasonography was performed on all participants in the supine position. Levator hiatal area measurements at rest, on maximal pelvic floor contraction, and during maximum Valsalva maneuver were collected before and after either spinal manipulation or a control intervention.

RESULTS

Levator hiatal area at rest increased significantly (P < .05) after spinal manipulation in the pregnant women, with no change postmanipulation in the nonpregnant women at rest or in any of the other measured parameters.

CONCLUSION

Spinal manipulation of pregnant women in their second trimester increased the levator hiatal area at rest and thus appears to relax the pelvic floor muscles. This did not occur in the nonpregnant control participants, suggesting that it may be pregnancy related.

Value of UVJ-M in the diagnosis of SUI in late pregnancy and postpartum

Stress urinary incontinence (SUI) is a common pelvic floor dysfunctional disorder in which leakage of urine occurs when there is abdominal pressure. The aim of the present study was to determine the value of stress urinary incontinences (SUIs) in late pregnancy and postpartum via detection of the mobility of the ureterovesical junction (UVJ-M) by using transperineal ultrasound. The study involved the continuous and random selection of 120 cases of early pregnant women and single births. The patients were divided into the SUI and non-SUI groups dependent on whether there was leakage of urine when abdominal pressure in the form of coughing, laughing and sneezing, was increased. UVJ-M was measured, the receiver operating characteristic (ROC) curve was drawn up and the threshold value was predicted. The results showed that, the SUI prevalence was 7.5 (9/120), 22.5 (27/120), 43.3 (52/120), and 5.8% (7/100), respectively, in 34, 36, and 38 gestational weeks, and 6 weeks after delivery. The SUI prevalence gradually increased with the gestational weeks, and differences were statistically significant. UVJ-M values increased with the gestational weeks, at 3.43±1.52, 6.77±0.98 and 2.35±1.04 mm, respectively. Statistically significant differences were identified. Results of the ROC analysis, based on measurement of UVJ-M between the late pregnancy and non-SUI groups, revealed that the optimal threshold was 8.66 mm, corresponding to a sensitivity of 89.5% and specificity of 66.7%. In conclusion, UVJ-M ≥6.59 mm was identified as the predicted value of SUI during late pregnancy, and UVJ-M ≥8.66 mm the predicted value of SUI after delivery.

Physical activity and the pelvic floor

Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for women. However, future research is needed to fill the many gaps in our knowledge. Prospective studies are needed in all populations, including potentially vulnerable women, such as those with high genetic risk, levator ani muscle injury, or asymptomatic pelvic organ prolapse, and on women during potentially vulnerable life periods, such as the early postpartum or postoperative periods.

AVALIAÇÃO DO ASSOALHO PÉLVICO DE ATLETAS: EXISTE RELAÇÃO COM A INCONTINÊNCIA URINÁRIA?

Introdução O assoalho pélvico feminino é formado por um conjunto de músculos, fáscias e ligamentos que sustentam os órgãos pélvicos (bexiga, ânus e vagina). A lesão destas estruturas, devido à idade avançada e parto podem levar à incontinência urinária. Entretanto, ainda não se sabe se o exercício de alta intensidade é capaz de lesar este conjunto músculo-aponevrótico, levando à incontinência urinária. Objetivo Comparar a capacidade de contração dos músculos do assoalho pélvico entre mulheres sedentárias e atletas de elite, e verificar se existe associação com a ocorrência de incontinência urinária durante a atividade física. Métodos Estudo caso-controle que incluiu 93 mulheres (49 atletas e 44 sedentárias) convidadas a responder o questionário "International Consultation on Incontinence Questionnaire - Short Form" e realizar avaliação funcional do assoalho pélvico. As atletas (grupo caso) eram praticantes de corrida de longa distância, basquete e ginástica olímpica. As sedentárias (grupo controle) realizavam menos de 150 minutos por semana de atividades moderadas ou vigorosas. A aferição da pressão de contração foi feita por meio de um perineômetro digital de precisão. Resultados Os grupos foram homogêneos quanto à idade e índice de massa corpórea. As atletas apresentaram maiores valores de pressão vaginal máxima (70,1±2,4 cmH2O) quando comparadas às sedentárias (34,3±1,7 cmH2O), (p<0,001). As atletas praticantes de basquete tiveram os maiores valores da pressão vaginal máxima (77,2 cmH2O) quando comparadas às ginastas (65,5 cmH2O) e corredoras (65,4 cmH2O). A prevalência de incontinência urinária nas atletas foi de 76% e somente 16% nas sedentárias (p=0,005). Conclusão Embora a capacidade de contração do assoalho pélvico em atletas de elite seja superior às sedentárias, a prevalência de incontinência urinaria foi elevada neste grupo de praticantes de esporte de alto rendimento e alto impacto.

Levator Plate Upward Lift on Dynamic Sonography and Levator Muscle Strength

OBJECTIVES

To compare digital palpation with levator plate lift measured by endovaginal and transperineal dynamic sonography.

METHODS

Dynamic transperineal and endovaginal sonographic examinations were performed as part of multicompartmental pelvic floor functional assessment. Patients were instructed to perform Kegel contractions while a probe captured a video clip of levator plate movement at rest and during contraction in a 2-dimensional midsagittal posterior view. We measured the distance between the levator plate and the probe on endovaginal sonography as well as the distance between the levator plate and the gothic arch of the pubis on transperineal sonography. The change in diameter (lift) and levator plate lift ratio (lift/rest × 100) were calculated. Pelvic floor muscle strength was assessed by digital palpation and divided into functional and nonfunctional groups according to the Modified Oxford Scale. Mean differences in levator plate upward lift were compared by Modified Oxford Scale scores using Student t tests and analysis of variance.

RESULTS

Seventy-four women were available for analysis. The mean age was 55 (SD, 11.9) years. When measured by vaginal dynamic sonography, mean lift and lift/rest ratio values increased with increasing Modified Oxford Scale score (analysis of variance, P= .09 and .04, respectively). When scores were categorized to represent nonfunctional (0-1) and functional (2-5) muscle strength groups, the mean lift (3.2 versus 4.6 mm; P = .03) and lift/rest ratio (13% versus 20%; P = .01) values were significantly higher in women with functional muscle strength. All patients with lift of 30% or greater detected by vaginal sonography had functional muscle strength.

CONCLUSIONS

A greater levator plate lift ratio detected by dynamic endovaginal sonography was associated with higher muscle strength as determined by the Modified Oxford Scale. This novel measurement can be incorporated into sonographic evaluation of levator ani function.

Correlations of third-trimester hiatal biometry obtained using four-dimensional translabial ultrasonography with the delivery route in nulliparous pregnant women

Purpose:

The goal of this study was to evaluate normal hiatal dimensions in the third trimester in nulliparous Thai pregnant women and to establish which biometric factors were associated with various pregnancy outcomes.

Methods:

Fifty-seven consecutive nulliparous pregnant Thai women in their third trimester were recruited on a voluntary basis from April to October 2014. All subjects underwent four-dimensional (4D) translabial ultrasonography. Hiatal biometric parameters were measured at rest, while performing a Valsalva maneuver, and during contraction. Information about the patients’ eventual deliveries was obtained from their medical records.

Results:

The mean values of the patients’ age, body mass index, and gestational age at the time of examination were 27.4±5.47 years, 26.7±3.48 kg/m², and 36.6±1.49 weeks, respectively. No subjects had vaginal lumps or experienced prolapse greater than stage 1 of the Pelvic Organ Prolapse Quantification system. Ultrasonography showed that the mean values of the hiatal area at rest, while performing a Valsalva maneuver, and during contraction were 13.10±2.92 cm², 17.50±4.81 cm², and 9.69±2.09 cm², respectively. The hiatal area at rest, the axial measurement at rest, and the axial measurement while performing a Valsalva maneuver were significantly associated with the route of delivery (P=0.02, P=0.04, and P=0.03, respectively).

Conclusion:

The route of delivery was associated with hiatal biometric values measured using 4D translabial ultrasonography, based on the results of nulliparous Thai women in the third trimester.
