Acute Effect of a Half-Marathon over the Muscular Function and Electromyographic Activity of the Pelvic Floor in Female Runners with or without Urinary Incontinence: A Pilot Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:ijerph20085535. [PMID: 37107817 PMCID: PMC10138407 DOI: 10.3390/ijerph20085535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 04/08/2023] [Accepted: 04/13/2023] [Indexed: 05/11/2023]
Abstract
OBJECTIVE to verify the acute effect of running a half marathon on pelvic floor muscle (PFM) function and electromyographic (EMG) activity in female runners with and without urinary incontinence. METHODS This is a cross-sectional pilot study. The sample was divided into two groups: runners with urinary incontinence (with UI) and runners without urinary incontinence (without UI). A semi-structured form and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) were used for data collection. The EMG and PFM function were evaluated using the PERFECT method before and immediately after running a half marathon. RESULTS A total of 14 runners were included (8 with UI; 6 without UI). Runners with and without UI did not show significant differences for EMG and PERFECT. The acute effects of the half marathon on runners without UI were reduced PFM function in terms of strength (p = 0.00), reduced endurance (p = 0.02), and reduced repetition (p = 0.03), and an increase in EMG measured by the median frequency (p = 0.02). Runners with UI showed reduced PFM function in terms of strength (p = 0.05) and repetition (p = 0.01). CONCLUSION there was no difference in the acute effects of the half marathon on PFM function and EMG in women with and without UI.

Abstract
Introduction Maintaining continence and providing support to the abdominal contents and sexual functioning are among the primary roles of pelvic floor muscles. The pelvic floor muscles work in synergy with the abdominal muscle to perform these functions. Abdominal muscle activation in the sagittal plane is influenced by the lumbar spine posture. As pelvic floor dysfunction is common among post-menopausal women, this study aims to find out the relationship between lumbar posture and electromyographic (EMG) activity of the rectus abdominis (RA) muscle and vaginal pressure (VP) as a functioning of the pelvic floor muscles among osteoporotic post-menopausal females. Methods A total of 78 osteoporotic post-menopausal women were recruited and allocated into three groups depending on lumbar lordotic angle, namely normal lordosis (n=26) hyperlordosis (n=26), and hypolordosis (n=26). All the subjects were recorded for RA EMG activity and VP for pelvic floor function in the quiet standing (QS) position, and voluntary dynamic tasks such as maximal coughing (MC) and Valsalva maneuver (VM). Data were analyzed using one-way analysis of variance (ANOVA) and post hoc analysis. A 5% probability level was considered statistically significant, i.e., p<0.05. Results The results showed a significant reduction in the RA activity and VP during the dynamic tasks (MC and VM) among subjects with the altered lumbar lordotic angle (p<0.05). The reduction in RA activity and VP was found to be significantly higher (p<0.05) in subjects with hyperlordotic lumbar spine than in those with hypolordotic lumbar spine as compared to normal lordosis during QS, MC, and VM. Conclusion We conclude that osteoporotic post-menopausal women with different lumbar lordotic angle show variations in RA activity and pressure generated by the vagina as a function of the pelvic floor during voluntary dynamic tasks.

Abstract
Purpose: Postoperative physiotherapy in conjunction with pelvic organ prolapse (POP) surgery is still under-investigated and controversial. In this randomized controlled trial, pelvic floor muscle training (PFMT) and abdominal training were compared with a control condition (standard in-hospital treatment). Method: Eighty-one women were randomized to one of three groups. The Prolapse Quality of Life questionnaire, two-dimensional ultrasound, Pelvic Organ Prolapse Quantification System scale, the PERFECT (power, endurance, repetitions, fast contractions, every contraction timed) scheme, electromyography, Sahrmann scale, and pressure biofeedback unit (PBU) were used to measure quality of life (QOL), POP, and pelvic floor and abdominal muscle function. A mixed-model analysis of variance and the Kruskal-Wallis test was used for analysis. Results: Beneficial effects (p < 0.05) were found for the PFMT group - increased power, number of fast contractions, amount of movement, endurance, and Sahrmann and PBU measures - compared with the control group. Abdominal training led to a significant (p < 0.05) increase in bulging and discomfort, number of pelvic floor muscle contractions, and Sahrmann and PBU measures compared with the control condition; both groups showed significantly increased urinary frequency (p < 0.05). Conclusions: Postoperative physiotherapy did not have a beneficial effect on QOL or POP symptoms. PFMT and abdominal training had beneficial effects on pelvic floor muscle function and abdominal muscle measures. Additional abdominal training led to increased symptoms.

Abstract
Objectives: This study evaluated if imagining interrupting the flow of urine really elicits contractions of the pelvic floor muscles (PFM) in stress-incontinent postpartum women. Methods: A total of 21 postpartum women with recent vaginal deliveries performed four trials of Kegel’s exercises, each prompted by a different contraction technique. PFM activities were measured with a surface electromyography via a vaginal electrode. Inferential statistics of repeated-measures one-way analysis of variance with Bonferroni post hoc analysis were performed to compare the effective recruitment of the PFMs across the four trials. Results: PFM activities significantly varied across the four trials ( p<0.001), with ‘imagination of interrupting urine flow’ eliciting the least muscular activity (25.40±10.98) and ‘abdominal bracing with hip adduction’ elicited the highest activity (49.67±11.33). Conclusion: Findings showed that utilizing many contraction techniques during Kegel’s education is more effective compared to educating patients with one contraction technique. Level of Evidence: Level 2.

Abstract
Purpose There may be a strong association among stress urinary incontinence (SUI), low back pain (LBP), and core muscle endurance (CME) in married women. This study is aimed at evaluating the prevalence and clinical association between SUI, CME, and LBP among married women in Saudi Arabia. Methods The study was based on a case-control research design, conducted among 143 women with LBP (mean age, 32 ± 7.4 years) and 160 healthy women (mean age, 31.7 ± 6.7 years). SUI, CME, and functional disability were assessed using the international consultation on the Incontinence Questionnaire-Short Form (ICIQ-SF), prone plank test (PP), and Oswestry Disability Index for LBP-United Arab Emirates edition (ODI-UAE). Results The prevalence of SUI was found to be 60% in the LBP group while 20% in the control group. CME revealed a stronger negative correlation with SUI in the LBP group (rs = −0.75) than in the control group (rs = −0.63). Conclusions The prevalence of SUI was observed higher in women with LBP than healthy women. CME exhibited a stronger association with SUI than LBP among women with LBP compared to healthy women in Saudi Arabia. Therefore, the role of CME in SUI development or vice versa among married women with LBP may be subjected to further research.

Abstract
STUDY OBJECTIVE To determine the overall frequency of urinary incontinence in pregnant adolescents, focusing particularly on the presence of symptoms of stress urinary incontinence (SUI) and coital incontinence (CI), and to describe the biological, sociodemographic, clinical, urinary, reproductive, sexual, and lifestyle factors associated with incontinence. DESIGN A cross-sectional, descriptive study. SETTING The outpatient clinic for high-risk pregnancies at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) in Recife, Pernambuco, in the Northeast of Brazil. PARTICIPANTS A convenience sample of 103 pregnant adolescents who attended for prenatal consultations during the study period. INTERVENTIONS Data were collected on the participants' characteristics and information based on the Incontinence Severity Index (ISI) questionnaire. MAIN OUTCOME MEASURES Frequency of urinary incontinence and possible correlations between the women's characteristics and SUI and CI symptoms. RESULTS Mean age (±standard deviation) was 16.76 ± 1.8 years. Urinary incontinence was present in 60.1% of the patients. Of these, 37.8% had SUI and 33.9% CI. In addition, 30.8% of the patients with CI also had SUI. There were statistically significant associations between CI and the occurrence of SUI prior to pregnancy (100%; PR: 1.77; 95% CI: 1.48-2.13; P = .011), between SUI and chronic coughing (60%; PR = 1.95; 95% CI: 1.23-3.09; P = .009), and between CI and height (41.9%; PR = 1.00; 95% CI: 0.27-1.00; P = .036). CONCLUSION Urinary incontinence is a dysfunction that may affect pregnant adolescents, with symptoms possibly beginning as early as the first trimester of pregnancy.

Postural Sensorimotor Control on Anorectal Pressures and Pelvic Floor Muscle Tone and Strength: Effects of a Single 5P ® LOGSURF Session. A Cross-Sectional Preliminary Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18073708. [PMID: 33918217 PMCID: PMC8037751 DOI: 10.3390/ijerph18073708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 03/24/2021] [Accepted: 03/30/2021] [Indexed: 11/23/2022]
Abstract
Pelvic floor dysfunction (PFD) is a functional condition present most frequently in women. Despite pelvic floor muscle training being considered by the International Continence Society (ICS) as the first-line treatment in uncomplicated urinary incontinence, other more comprehensive postural methods as 5P® LOGSURF have emerged. This preliminary cross-sectional study explores the effects of a single 5P® LOGSURF session on pelvic floor muscle (PFM) tone and strength (MVC), resting anal tone, intrarectal pressure, and deep abdominal muscles activation. Thirty women were included (11 without PFD and 19 with PFD). Primary outcome measures were PFM tone, PFM MVC and resting anal tone and secondary measures outcomes were intrarectal pressure and deep abdominal activation. All outcome measures were collected before, throughout and after a single 30′ 5P® LOGSURF session. The findings from this study suggest that PFM tone (PFD group: p = 0.09, d = 0.72; non-PFD group: p = 0.003, d = 0.49) and PFM MVC (PFD group: p = 0.016; non-PFD group: p = 0.005) decreased in both groups after a single 5P® LOGSURF session, with a medium effect size for women with PFD. Contrarily, deep abdominal muscle MVC increased (PFD group: p < 0.001; non-PFD group: p = 0.03). Intrarectal pressure and resting anal tone decreased in both groups throughout the session. These results suggest that 5P® LOGSURF method may be interesting if is performed by women with mild symptoms of PFD or healthy women to achieve a decrease in PFM tone in women who manifested pain to intracavitary techniques or practices. Further research with higher sample sizes and long-term are necessary for generalizing.

Abstract
The management of pelvic floor dysfunctions might need to be based on a comprehensive neuro-musculoskeletal therapy such as The Rolf Method of Structural Integration (SI). The aim of the study was to evaluate the pelvic floor muscle (PFM) after the tenth session of SI by using surface electromyography (sEMG). This was a randomized, interventional study. Thirty-three healthy women were randomly assigned to the experimental (SI) or control group. The outcome measures included PFM bioelectrical activity, assessed using sEMG and endovaginal probes. An intervention in the SI group included 60 min of SI once a week, and teaching on how to contract and relax PFMs; in the control group, only the teaching was carried out. In the SI group, a significant difference was found between the PFM sEMG activity during “pre-baseline rest” (p < 0.014) and that during “rest after tonic contraction” (p = 0.021) in the supine position, as were significant increases in “phasic contraction” in the standing position (p = 0.014). In the intergroup comparison, higher PFM sEMG activity after the intervention “phasic contraction” (p = 0.037) and “pre-baseline rest” (p = 0.028) was observed in the SI group. The SI intervention significantly changes some functional bioelectrical activity of PFMs, providing a basis for further research on a new approach to PFM facilitation, particularly in clinical populations.

Abstract
BACKGROUND Although pelvic floor muscle training is widely recommendedin the literature as the gold standard for the treatment of pelvic floor dysfunctions, such as urinary incontinence, interest in other exercise regimens is increasing. However, it is unknown whether other exercise regimens increase pelvic floor muscle strength. METHODS This was a systematic review of randomized clinical trials found in PEDro, tridatabase, Cochrane and PubMed on the efficacy of nonspecific exercises, such as Pilates, the Paula method, and hypopressive exercises, in strengthening pelvic floor muscles in adults without underlying neurological disorders and with or without pelvic floor dysfunction. RESULTS Seven studies were analyzed, and the results demonstrated that Pilates, the Paula method, and hypopressive exercises are ineffective in increasing pelvic muscle strength unless they are performed in conjunction with pelvic floor muscle training. The protocol was registered in the PROSPERO database (www.crd.york.ac.uk/prospero/) under the number CRD42019123396. CONCLUSION Considering the available studies, we have concluded that Pilates, the Paula method and hypopressive exercises performed alone do not increase pelvic floor muscle strength. Pelvic floor muscle training continues to be the gold standard for increasing pelvic muscle strength.

Abstract
There is an ongoing discussion regarding abdominal muscle (AbM) and pelvic floor muscle (PFM) synergism. Therefore, this study aimed to investigate the cocontraction between AbMs and PFMs in women with or without pelvic floor dysfunction (PFD). The following databases were searched up to December 21, 2018: MEDLINE, EMBASE, LILACS, PEDro and CENTRAL. We included any study that assessed the cocontraction between PFMs and AbMs in women with and without PFD. Two reviewers independently screened eligible articles and extracted data. The outcomes were extracted and analyzed as continuous variables with random effect models. Twenty studies were included. A meta-analysis did not show differences in women with and without PFD. However, a sensitivity analysis suggested cocontraction of the transversus abdominis (TrA) during PFM contraction in healthy women (standardized mean difference (SMD) -1.02 [95% confidence interval (CI) -1.90 to -0.14], P=0.02; I2= not applicable; very low quality of evidence). Women with PFD during contraction of PFMs showed cocontraction of the obliquus internus (OI) (SMD 1.10 [95% CI 0.27 to 1.94], P=0.01; I2= not applicable; very low quality of evidence), and obliquus externus (OE) (SMD 2.08 [95% CI 1.10 to 3.06], P<0.0001; I2 = not applicable; very low quality of evidence). Increased cocontraction of the TrA may be associated with maximal contraction of PFMs in women without PFD. On the other hand, there is likely an increased cocontraction with the OI and OE in women with PFD.

Abstract
Purpose To characterize the electromyographic activity of abdominal striated muscles during micturition in urethane-anesthetized female mice, and to quantitatively evaluate the contribution of abdominal responses to efficient voiding. Methods Cystometric and multichannel electromyographic recordings were integrated to enable a comprehensive evaluation during micturition in urethane-anesthetized female mice. Four major abdominal muscle domains were evaluated: the external oblique, internal oblique, and superior and inferior rectus abdominis. To further characterize the functionality of the abdominal muscles, pancuronium bromide (25 μg/mL or 50 μg/mL, abdominal surface) was applied as a blocking agent of neuromuscular junctions. Results We observed a robust activation of the abdominal muscles during voiding, with a consistent onset/offset concomitant with the bladder pressure threshold. Pancuronium was effective, in a dose-dependent fashion, for partial and complete blockage of abdominal activity. Electromyographic discharges during voiding were significantly inhibited by applying pancuronium. Decreased cystometric parameters were recorded, including the peak pressure, pressure threshold, intercontractile interval, and voiding duration, suggesting that the voiding efficiency was significantly compromised by abdominal muscle relaxation. Conclusions The relevance of the abdominal striated musculature for micturition has remained a topic of debate in human physiology. Although the study was performed on anesthetized mice, these results support the existence of synergistic abdominal electromyographic activity facilitating voiding in anesthetized mice. Further, our study presents a rodent model that can be used for future investigations into micturition-related abdominal activity.
