Pelvic floor muscle displacement during jumps in continent and incontinent women: An exploratory study

Technologies for Evaluation of Pelvic Floor Functionality: A Systematic Review

Pelvic floor dysfunction is a common problem in women and has a negative impact on their quality of life. The aim of this review was to provide a general overview of the current state of technology used to assess pelvic floor functionality. It also provides literature research of the physiological and anatomical factors that correlate with pelvic floor health. This systematic review was conducted according to the PRISMA guidelines. The PubMed, ScienceDirect, Cochrane Library, and IEEE databases were searched for publications on sensor technology for the assessment of pelvic floor functionality. Anatomical and physiological parameters were identified through a manual search. In the systematic review, 114 publications were included. Twelve different sensor technologies were identified. Information on the obtained parameters, sensor position, test activities, and subject characteristics was prepared in tabular form from each publication. A total of 16 anatomical and physiological parameters influencing pelvic floor health were identified in 17 published studies and ranked for their statistical significance. Taken together, this review could serve as a basis for the development of novel sensors which could allow for quantifiable prevention and diagnosis, as well as particularized documentation of rehabilitation processes related to pelvic floor dysfunctions.

Do pelvic floor muscle function parameters differ in women according to continence status? A systematic review

BACKGROUND

Current literature highlights the difficulty in identifying which pelvic floor muscle (PFM) functions are correlated with urinary incontinence (UI).

AIM

In this study, we compared parameters of PFM function (strength, endurance, tone, control, reaction, and/or coordination) according to continence status in women (presence or absence, type and/or severity of urinary incontinence).

EVIDENCE ACQUISITION

A systematic review was conducted following the 2020 PRISMA guidelines. Three databases (Pubmed, Web of Science, and LiSSa) were searched from inception to December 31, 2021. Assessment of risk of bias was performed using the Joanna Briggs Institute critical appraisal checklist.

EVIDENCE SYNTHESIS

The initial research yielded 4733 studies. Forty-two studies met the inclusion criteria, including 4015 participants. No statistical association was found between PFM function and the presence or absence of UI, the different type of UI or the different levels of severity of UI. The heterogeneity in methodologies and analyzes of the results only with the P-value are important limitations of this review.

CONCLUSION

It appears that muscle function is not always associated with presence or absence of UI. No association is found between PFM function and type or severity of UI. These results reinforce the need to carry out a bio-psycho-social evaluation of UI that does not only focus on PFM functions. As such, the results reported herein can be considered a resource for more specific research.

Sports Medicine and the Pelvic Floor

ABSTRACT

The female athlete is seen as a specialist population meaning female considerations, such as pelvic floor dysfunction, are not widely taught within sports medicine. Females have unique anatomical characteristics compared with males including a wider pelvic diameter and an additional orifice in the form of the vagina. Furthermore, symptoms of pelvic floor dysfunction are prevalent among female athletes and transitional periods in their lifespan. They also are a barrier to training and performance. Therefore, it is essential that sports medicine practitioners understand how to identify and manage pelvic floor dysfunction. This report aims to describe the anatomy and function of the pelvic floor, outline the types and rates of pelvic floor dysfunction, discuss evidence-based management, and raise awareness of perinatal bodily changes. Practical recommendations are made to aid sports organizations and sports medicine practitioners in supporting the female athlete and in using a proactive approach to manage the perinatal athlete.

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 Among Elite Track and Field Athletes According to Their Event Specialization: A Cross-Sectional Study

Background

Physical effort in sports practice is an important trigger for urinary incontinence (UI). Among high-impact sports, all track and field events require continuous ground impacts and/or abdominal contractions that increase intra-abdominal pressure and impact on the pelvic floor musculature. However, studies to date have not taken into account the specific sports tasks that elite track and field athletes perform according to the competitive events for which they are training.

Methods

This cross-sectional study describes the prevalence, type, and severity of UI among elite track and field athletes considering their event specialization and training characteristics. A total of 211 female and 128 male elite track and field athletes answered an online questionnaire including anthropometric measures, medical history, training characteristics, and UI symptoms. To determine self-reported UI, the International Consultation on Incontinence Questionnaire-UI Short-Form (ICIQ-UI-SF) was used. To determine UI type and severity, the incontinence questionnaire and incontinence severity index were used, respectively.

Results

The ICIQ-UI-SF showed that 51.7% of female and 18.8% of male athletes had UI, with stress UI (SUI) being the most frequent type (64.4%) for female and urge UI for male athletes (52.9%). Of athletes who were not identified as having UI according to the questionnaires, 24.6% of female and 13.6% of male athletes experienced urine leakage during training, mainly during jumping. Although training characteristics (experience, volume, and resting) were not related to UI, female athletes specializing in vertical jumps showed significantly lower UI prevalence compared to those specializing in horizontal jumps (χ² [1] = 4.409, p = 0.040), middle-distance running (χ² [1] = 4.523, p = 0.033), and sprint/hurdles events (χ² [1] = 4.113, p = 0.043). These female athletes also displayed the lowest training volume. No differences were shown for males (p > 0.05).

Conclusions

Over half of the elite track and field female athletes have self-reported UI, especially SUI, and prevalence is higher when considering urine leakage events during training. Training characteristics and specialization were not related to UI identified by questionnaires, but female athletes specializing in vertical jump events showed the lowest prevalence and training volume. Males showed significantly lower prevalence, without correlation with their specialization. Sport professionals should increase UI detection among elite athletes and design-specific approaches that consider their physical demands to make visible, prevent, or improve pelvic floor dysfunction in this population.

Therapeutic exercise to improve pelvic floor muscle function in a female sporting population: a systematic review and meta-analysis

BACKGROUND

Despite the high prevalence of pelvic floor dysfunction (PFD) among women who participate in sports, and the efforts made to affect these pathologies through pelvic floor muscle (PFM) training, its effects on PFM function remain unclear.

OBJECTIVE

To evaluate the effects of therapeutic exercise programmes on PFM function and quality of life in female athletes and physically active women.

DATA SOURCES

The following databases were searched: MEDLINE, SCIELO, LILACS, SPORTDiscus, SCOPUS, CINHAL, SCIELO, PEDro, ScienceDirect and COCHRANE from January 2010 to May 2020.

STUDY SELECTION

Study selection criteria included clinical trials that recruited either female athletes or physically active women, and evaluated the effects of therapeutic exercise programmes on PFM function.

DATA SYNTHESIS

Ten studies met the eligibility criteria, capturing a total of 246 participants, of which 180 were apparently healthy individuals and 66 suffered from PFD.

RESULTS

Meta-analysis revealed significant improvements in maximal voluntary contraction of the PFMs and reduction of urine leakage after the exercise programmes, although no effects were found for vaginal resting pressure.

LIMITATIONS

Most of the studies reviewed had a small sample size and a high risk of bias.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

Data suggest the benefits of therapeutic exercise on PFM function, PFD symptoms and quality of life after therapeutic exercise programmes in women who participate in sports. Incorporating therapeutic exercises designed to increase PFM function into physical activity routines could be beneficial for both healthy women and those suffering from PFD. However, due to the stated limitations, firm conclusions cannot be made. Systematic Review Registration Number PROSPERO CRD42020167243.

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.

The pathophysiology of stress urinary incontinence: a systematic review and meta-analysis

Introduction and hypothesis

To evaluate the evidence for pathologies underlying stress urinary incontinence (SUI) in women.

Methods

For the data sources, a structured search of the peer-reviewed literature (English language; 1960–April 2020) was conducted using predefined key terms in PubMed and Embase. Google Scholar was also searched. Peer-reviewed manuscripts that reported on anatomical, physiological or functional differences between females with signs and/or symptoms consistent with SUI and a concurrently recruited control group of continent females without any substantive urogynecological symptoms. Of 4629 publications screened, 84 met the inclusion criteria and were retained, among which 24 were included in meta-analyses.

Results

Selection bias was moderate to high; < 25% of studies controlled for major confounding variables for SUI (e.g., age, BMI and parity). There was a lack of standardization of methods among studies, and several measurement issues were identified. Results were synthesized qualitatively, and, where possible, random-effects meta-analyses were conducted. Deficits in urethral and bladder neck structure and support, neuromuscular and mechanical function of the striated urethral sphincter (SUS) and levator ani muscles all appear to be associated with SUI. Meta-analyses showed that observed bladder neck dilation and lower functional urethral length, bladder neck support and maximum urethral closure pressures are strong characteristic signs of SUI.

Conclusion

The pathology of SUI is multifactorial, with strong evidence pointing to bladder neck and urethral incompetence. While there is also evidence of impaired urethral support and levator ani function, standardized approaches to measurement are needed to generate higher levels of evidence.
