Effectiveness of Hypopressive Exercises in Women with Pelvic Floor Dysfunction: A Randomised Controlled Trial

Effects of Hypopressive Exercise on Dynamic Neuromuscular Control in Female Roller-Skaters

The effects of hypopressive exercise (HE) on dynamic balance have never been studied. We aimed to study the effects of a HE program on dynamic balance, posterior chain kinematics and expiratory peak flow on female competitive roller skaters over a 6-week training period. Twenty competitive female roller-skaters (13-22 years of age, SD 2.25) performed a 30-minute HE session once weekly before the regular roller-skating practice for 6 weeks. The HE program consisted of breathing and postural awareness exercises in addition to 5 basic HE poses performed three times each. Dynamic neuromuscular control was assessed with the Y-Balance Test (YBT), posterior back chain kinematics with the sit and reach test and peak expiratory flow rate with a digital spirometer. Paired t-test revealed significant differences between the measurement periods for all YBT leg directions and composite score (p ≤ 0.01). Significant differences were also revealed between baseline and after the intervention for the sit and reach test (p ≤ 0.01) and peak expiratory flow (p = 0.01). No differences in forced expiratory volume in the first second were found (p = 0.04). These preliminary findings suggest that a 6-week HE program could be a feasible neuromuscular option for training dynamic balance, posterior back chain kinematics and peak expiratory flow in female roller-skaters.

Effects of hypopressive exercises on pelvic floor and abdominal muscles in adult women: A systematic review of randomized clinical trials

INTRODUCTION

Hypopressive exercises (HE) are postural and breathing exercises that activate deep muscles in the abdomen and pelvic floor. Despite this, there is still no consensus in the literature on its real effectiveness. The objective was to analyze the effects of HE on the abdominal and pelvic floor muscles in women with or without dysfunctions in these regions.

METHODS

This is a systematic review of randomized clinical trials found in the PEDro, PubMed, Cochrane, LILACS, and Embase databases. We include studies that evaluate the effects of HE (with or without other techniques) on the pelvic floor and abdominal region for 8 weeks or more, in women over 18 years old, with or without dysfunction in these regions, with the presence of a control group (active or passive).

RESULTS

HE were effective in improving strength, tone, and reducing symptoms of pelvic floor dysfunctions, in magnitude less than (in two studies) or equal (in one study) to the pelvic floor muscle training (PFMT). When HE were performed with PFMT in the same group, no additional benefits were found. Only one study evaluated abdominal muscles activation, where HE were effective in improving postural control and activation of the transversus abdominis muscle.

CONCLUSIONS

The HE presented positive results to the evaluated parameters. However, the information is still preliminary and scarce. There are methodological divergences regarding the execution, follow-up and standardization of the method, which could affect the results. According to the existing information, HE cannot yet be reliably indicated for the treatment of the pelvic floor, despite pointing out relevant results in some studies. More randomized clinical trials and long-term studies are needed to analyze the effects of HE not only for pelvic floor, but also for other regions, such as abdominal muscles and related dysfunctions.

[Home therapeutic adherence of pelvic floor muscle exercises in urinary incontinence]

Background

Urinary incontinence (UI) is a medical and social problem that has a great impact on the quality of life of women. Pelvic floor muscle strengthening exercises have been shown to be a form of conservative treatment. However, there is still high failure in this treatment.

Objective

To analyze the factors associated with low home therapeutic adherence to pelvic floor exercises in patients with UI.

Material and methods

An analytical cross-sectional prolective study was carried out in women aged 20-85 years, with UI and under conservative treatment with pelvic floor muscle exercises. They were questioned about their demographic data; the Morisky Green therapeutic adherence questionnaire and the Likert-type satisfaction scale were applied on the results of the questionnaire.

Results

235 women with UI and with a prescription for pelvic floor muscle exercises, with a median of 55 (46-64) years, were analyzed. The lack of adherence to pelvic floor exercises was observed in 130 (55.32%), whose causes were their work (37.69%), forgetfulness (23.08%) and lack of interest (12.08%). The risk factors for non-adherence were having 3 or less children (OR 1.81 [95% CI 1.10-3.23], p = 0.02), and not feeling satisfied with the exercises (OR 6.70 [95% CI 3.75-11.97], p < 0.001.

Conclusion

The factors associated with low home therapeutic adherence to pelvic floor exercises in patients with urinary incontinence were having 3 or less children and not being satisfied with the results.

Predictive value of abdominal wall scar score for pelvic floor function rehabilitation, vaginal microecology and complications after cesarean section

Objective

To explore the predictive value of the abdominal wall scar score for pelvic floor function rehabilitation, vaginal microecology and complications after cesarean section.

Methods

A total of 120 pregnant women who underwent cesarean section in our hospital from January to December 2022 were selected. The patients were divided into observation group (score ≥ 60, n = 52) and control group (score < 60, n = 68) according to the preoperative score of abdominal wall scar and whether the score exceeded 60. The pelvic floor function rehabilitation, vaginal microecology and complications were compared between the two groups, and the score of abdominal wall scar was evaluated by receiver operating characteristic (ROC) curve. The predictive value of pelvic floor function rehabilitation, vaginal microecology and complications after cesarean section was evaluated.

Results

There were significant differences between the two groups in postpartum class I and class II muscle fiber strength and pelvic floor muscle potential (P < 0.05). ROC curve showed that the AUC of abdominal scar score in predicting pelvic floor function rehabilitation was 0.806 (95% CI [0.684-0.927]), the specificity was 80.17%, and the sensitivity was 79.76%. There was significant difference in the abnormal rate of leukocte estrase (LE) and Acetylaminoglucosidase (NAG) between the two groups (P < 0.05). ROC curve showed that the AUC of abdominal scar score in predicting vaginal microecology was 0.871 (95% CI [0.776-0.966]), the specificity was 85.09%, and the sensitivity was 82.36%. There was significant difference in the incidence of postpartum complications between the two groups (P < 0.05). ROC curve showed that the AUC of abdominal scar score in predicting complications was 0.844 (95% CI [0.735-0.953]), the specificity was 82.27%, and the sensitivity was 81.15%.

Conclusion

The abdominal scar score has a certain effect on predicting the recovery of pelvic floor function, vaginal microecology and complications after cesarean section. Therefore, it can help the medical staff to adjust the treatment measures in time, which can be used as a means of preoperative auxiliary examination.

Impact and Influence of Urinary Incontinence on Physical Activity Levels

Background

The benefits of physical activity are numerous on both physical and mental levels. Urinary incontinence (UI) can influence physical activity level; among US women, nearly two out of three view this problem as a barrier to physical activity, meaning that they do not exercise, exercise less, or even have to change their activity routines to accommodate this pelvic floor dysfunction.

Objective

To determine whether UI influences the pattern of physical activity and whether a greater impact of urinary symptoms could influence the level of physical activity.

Design setting and participants

An observational study was carried out with women in 2021 and 2022 in Spain.

Outcome measurements and statistical analysis

The main dependent variable was level physical activity, as measured by the International Physical Activity Questionnaire (IPAQ). The Urogenital Distress Inventory (UDI-6) scale was used to determine the presence of UI and its impact. Sociodemographic, health status, lifestyle and obstetric data were obtained. Bivariate and multivariate analyses were performed using binary logistic regression, obtaining adjusted odds ratio (aOR) with its 95% confidence interval (95% CI).

Results and limitations

A total of 1446 women participated, of whom 55.8% (807) had UI and 25.7% (371) reported low physical activity. Mixed incontinence (aOR: 1.53; 95% CI: 1.09-2.15) overall and a greater intensity of urinary symptoms (UDI-6 score; aOR: 1.014; 95% CI: 1.01-1.02) in the group of women with incontinence were statistically associated with a higher frequency of low physical activity. Other variables related to low physical activity were age, body mass index, pelvic pain, and income level (p < 0.001).

Conclusions

Mixed-type UI is associated with low-level physical activity or inactivity in the whole group of women, while among women with UI, the greater impact of the symptoms increases the probability of low physical activity or inactivity.

Patient summary

In this report, it is analyzed how urinary incontinence affects physical activity. It was found that women who suffer from mixed-type urinary incontinence have a low level of physical activity or inactivity, while those who experience a greater impact of urinary incontinence symptoms have an increased likelihood of having low physical activity or inactivity.

The state of pelvic floor muscle dynamometry: A scoping review

AIMS

To discuss the advantages and limitation of the different pelvic floor muscle (PFM) dynamometers available, both in research and industry, and to present the extent of variation between them in terms of structure, functioning, psychometric properties, and assessment procedures.

METHODS

We identified relevant studies from four databases (MEDLINE, Compendex, Web of Science, and Derwent Innovations Index) up to December 2020 using terms related to dynamometry and PFM. In addition, we conducted a hand search of the bibliographies of all relevant reports. Peer-reviewed papers, conference proceedings, patents and user's manuals for commercial dynamometers were included and assessed by two independent reviewers.

RESULTS

One hundred and one records were included and 23 PFM dynamometers from 15 research groups were identified. From these, 20 were considered as clinical dynamometers (meant for research settings) and three as personal dynamometers (developed by the industry). Overall, significant heterogeneity was found in their structure and functioning, which limits development of normative data for PFM force in women. Further research is needed to assess the psychometric properties of PFM dynamometers and to standardize assessment procedures.

CONCLUSION

This review points up to the heterogeneity of existing dynamometers and methods of assessing PFM function. It highlights the need to better document their design and assessment protocol methods. Additionally, this review recommends standards for new dynamometers to allow the establishment of normalized data.

Are hypopressive and other exercise programs effective for the treatment of pelvic organ prolapse?

INTRODUCTION AND HYPOTHESIS

Pelvic floor muscle training (PFMT) is effective for the treatment of pelvic organ prolapse (POP), but other exercise programs have also been promoted and used. The aim of this review was to evaluate the effect of hypopressive and other exercise programs besides PFMT for POP.

METHODS

A literature search was conducted on Ovid Medline, EMBASE, CINAHL, Cochrane, PEDro, and Scopus databases from January 1996 to 30 December 2021. Only randomized controlled trials (RCTs) were included. The keywords were combinations of "pelvic organ prolapse" or "urogenital prolapse," and "exercise therapy," "hypopressive exercise," "Kegel," "pelvic floor muscle training," "pelvic floor muscle exercises," "Pilates," "treatment," "yoga," "Tai Chi." Methodological quality was assessed using the PEDro rating scale (0-10).

RESULTS

Seven RCTs containing hypopressive exercise, yoga or breathing and hip muscle exercises in an inverted position were retrieved and analyzed. PEDro score ranged from 4 to 7. There was no additional effect of adding hypopressive exercise to PFMT, and PFMT was more effective than hypopressive exercise alone. The studies that included the term "yoga" included regular PFMT and thus can be classified as PFMT. Hip exercises in an inverted position added to PFMT vs PFMT alone showed better improvement in some secondary outcomes but not in the primary outcome, POP stage.

CONCLUSIONS

There are few RCTs assessing the effects of other exercise programs besides PFMT in the treatment of POP. To date, there is no evidence that other exercise programs are more effective than PFMT for POP.

Effects of hypopressive exercises on post-partum abdominal diastasis, trunk circumference, and mechanical properties of abdominopelvic tissues: a case series

BACKGROUND

Abdominal diastasis (AD) is highly prevalent at post-partum. Although several conservative approaches have been proposed, an effective and protocolized treatment is lacking for this condition.

OBJECTIVE

To identify modifications of inter-rectus abdominis distance (IRAD), trunk circumferences and mechanical properties of the AD, transversus abdominis and the pelvic floor (PF) muscles, after the application of hypopressive exercises (HE) and at a two-month follow-up in postpartum AD.

METHODS

Twelve volunteers with post-partum AD followed a four-week (three times a week) tailored program of HE. The main outcome was the IRAD, assessed at four specific supraumbilical points (3, 6, 9, and 12 cm). Abdominal circumference and respiratory expansion were measured at three different locations (axillar, xiphoid, and umbilical), and the mechanical properties of abdomino-pelvic tissues were also assessed using tonometry (MyotonPRO). Four evaluations were performed for all outcomes: at baseline, post-intervention, at a 1-month follow-up, and at a 2-month follow-up.

RESULTS

The IRAD of participants was reduced (p < .05), furthermore, some participants displayed no AD after the intervention period. In addition, the abdominal circumference increased, mainly at follow-up, whereas the thoracic respiratory expansion decreased a median of 2 cm. The tension and stiffness of the LA decreased, when assessed at 3 and 6 cm supraumbilical. Finally, the tension and elasticity of TA/IO and of the PF, and also the elasticity of the PF decreased after the intervention period. No complaints were identified in relation to the HE program or assessments.

CONCLUSION

A program of HE showed positive results for the reduction of post-partum AD. Different study designs should be performed to better explain the effects of HE for AD.

Rumba Dance Combined with Breathing Training as an Exercise Intervention in the Management of Stress Urinary Incontinence in Postmenopausal Women: A Randomized Controlled Trial

Purpose: Stress urinary incontinence (SUI) refers to involuntary leakage from the urethra, synchronous with exertion/effort, sneezing or coughing, which has a negative effect on quality of life. Studies have shown that mild-to-moderate physical activities reduce the risk of SUI by multiple mechanisms. The objective of this study was to determine whether the Rumba dance combined with breathing training (RDBT) can reduce the severity of incontinence and improve the quality of life of patients with SUI. Methods: A randomized clinical trial was conducted with women who were sedentary, were postmenopausal, reported mild-to-moderate SUI on a 1-h pad test, were not already engaged in Rumba dance and did not receive estrogen replacement therapy. The patients were randomly assigned to the RDBT group (n = 13) or the control group (n = 11). The intervention included 90 min of RDBT three times per week for 16 weeks, and the vaginal resting pressure (VRP), pelvic floor muscle (PFM) strength and endurance, 1-h pad test, International Consultation on Incontinence Questionnaire—Urinary Incontinence Short Form (ICIQ—UI SF), and the Incontinence Quality of Life Questionnaire (I—QOL) were measured or completed at baseline and 16 weeks. None of the participants reported adverse events. Results: The mean (±SD) age of the participants was 55.75 ± 5.58 years. After 16 weeks, in the RDBT group, the urine leakage on the 1-h pad test was significantly decreased −2.91 ± 0.49 from the baseline (p = 0.000). The VRP increased from 76.00 ± 16.23 cmH2O to 95.09 ± 18.90 cmH2O (p = 0.000), the PFM endurance of class I (−3.15 ± 1.99% vs. −0.46 ± 0.97%, p = 0.000) and class II (−0.69 ± 0.95% vs. −0.23 ± 0.44%, p = 0.065) increased, and the grades of PFM strength of class I and class II were significantly enhanced (p < 0.01). Finally, the severity of self-reported incontinence (ICIQ—UI SF) significantly decreased from 6.12 ± 2.15 to 3.81 ± 1.68 (p = 0.000), and quality of life (I—QOL) improved from 75.73 ± 11.93 to 83.48 ± 7.88 (p = 0.005). Conclusion: A 16-week RDBT program can increase PFM strength and endurance to reduce the severity of incontinence symptoms and improve the quality of life in patients with SUI, demonstrating the feasibility of recruiting and retaining postmenopausal women with SUI into a RDBT therapeutic program.

Knowledge of women during the third trimester of pregnancy regarding pelvic floor disorders

INTRODUCTION AND HYPOTHESIS

The objective was to examine knowledge regarding pelvic floor disorders (PFDs) among women during the third trimester of pregnancy.

METHODS

A cross-sectional study was conducted at a large teaching medical center in Israel between June and September 2020. Women in their third trimester (N = 649) were asked to complete the validated Hebrew and Arabic versions of the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). The PIKQ instrument examines the knowledge of two major PFDs: urinary incontinence (UI) and pelvic organ prolapse (POP). The study population included women over 18 years of age, in the third trimester, who speak and read Hebrew or Arabic fluently. Two separate scores were calculated, one for each section of the PIKQ. The association of questionnaire scores with the different independent variables was examined using Student's t test or one-way ANOVA. Correlations were examined using Pearson's or Spearman's correlation coefficient.

RESULTS

The Hebrew version was filled out by 405 women, and 244 women completed the Arabic version. The average questionnaire scores were 7.65 ± 2.8 and 5.32 ± 2 for the UI and POP sections respectively. Significantly higher average scores in both the UI and the POP sections were noted among health care workers (UI: 10.19 ± 2.3 vs 7.34 ± 2.6, p < 0.001; POP: 8.27 ± 2.7 vs 4.97 ± 2.6, p < 0.001), women with higher education (p < 0.001 in both parts) and those with higher incomes (p < 0.001 for both parts).

CONCLUSIONS

Knowledge of PFD among women in the third trimester of pregnancy in Israel was found to be low. Founding educational programs for targeted groups may improve both the knowledge of PFD and the quality of life for these women.

Kegel Exercise Training Program among Women with Urinary Incontinence

A common condition with a large global prevalence and a persistent medical taboo for many people is urinary incontinence. Around one in three women globally are impacted by it. The most frequently suggested physical therapy treatment for women with stress incontinence or urge incontinence is Kegel exercise (also called pelvic floor muscle training). This study aims to assess the effects of a Kegel exercise training program among women with urinary incontinence. The study was conducted at three government hospitals in Egypt's Port Said city's outpatient gynecological clinic. The intervention design was quasi-experimental. In total, 292 women with urine incontinence who visited the research sites made up the subjects. The necessary data were gathered using an interview questionnaire. Improvements in urinary incontinence and quality of life were positively correlated with daily Kegel exercise practice. Urinary incontinence has statistically significant positive correlations with age (p = 0.026), respiratory rate (p = 0.007), and body mass index (p = 0.026) as women grow older. Urinary incontinence, being single, and increasing pulse, however, had adversely significant negative correlations (p = 0.031 and 0.020, respectively). Urinary incontinence affects women's overall wellbeing, particularly in the emotional and social spheres, as well as their quality of life and their ability to participate in normal everyday activities. Following the adoption of the Kegel exercise training program, there was a substantial improvement in both urine incontinence and quality of life.

Efficacy of electro-acupuncture in postpartum with diastasis recti abdominis: A randomized controlled clinical trial

Background

Electro-acupuncture (EA) has promising effects on diastasis rectus abdominis (DRA), defined as a separation of the two muscle bellies of rectus abdominis. To study, there is scant knowledge or scarce high-quality evidence.

Objective

We aimed to evaluate the long-term efficacy and safety of EA in treating DRA during postpartum. It was assumed that the improvement of DRA was more obvious in the EA group than in the control group.

Design

Randomized, controlled, blinded trial (Clinical Trial Registration: ChiCTR2100041891).

Setting

Hangzhou Hospital of Traditional Chinese Medicine in China.

Participants

Females aged 20-45 years without a past medical history of pathological rectus abdominal dissection were recruited from DRA inclusion criteria from 42 days to 1 year postpartum.

Intervention

110 participants were randomly assigned in a 1:1 ratio to a control group with no EA intervention (n = 55), and EA group (n = 55). The EA group received ten sessions of EA combined with physical exercise or only physical exercise for 2 weeks with a 26-week follow-up.

Measurements

Outcomes were assessed at baseline, week 2, and week 26. The primary outcome was the change of the inter recti distance (IRD) and electromyographic evaluation of the pelvic floor. Secondary outcomes included elasticity of linea alba (LA), paraumbilical subcutaneous adipose tissue (SAT) measurement, body mass index (BMI), percentage body fat (F%), dyspepsia symptoms, menstrual symptoms, quality of life (QoL), pain performance of patients with lower back pain, postnatal depression symptoms (PDS), postpartum self-image, and DRA-related symptom assessment including urine leakage, frequency, and urgency, constipation, sexual dysfunction, and chronic pelvic pain.

Results

A total of 110 maternal (55 in each group) were recruited. The mean difference in IRD from baseline to week 2 and week 26 in all states of the two groups were reduced compared with those before treatment, with statistical significance (P < 0.05). The mean of IRD at the horizontal line of the umbilicus in the end-expiratory state was smaller in the EA group than in the control group, but the difference was not statistically significant (P > 0.05) at week 2. The mean of IRD at the horizontal line of the umbilicus in head-up and flexed knee state was smaller in the EA group than in the control group, and the difference was statistically significant (P < 0.05) at week 26. Five (9.1%) and thirteen (23.64%) adverse events were reported in EA and control groups, respectively. No serious adverse events were reported.

Limitation

The frequency intensity of EA parameters was selected between 4 and 6 because of individual tolerance differences.

Conclusion

EA is an effective approach to improve IRD, electromyographic evaluation of the pelvic floor, BMI, the elasticity of LA, paraumbilical SAT, and symptoms of DRA, with durable effects at 26 weeks.

The Impact of Hypopressive Abdominal Exercise on Linea Alba Morphology in Women Who Are Postpartum: A Short-Term Cross-Sectional Study

OBJECTIVE

The purpose of this study was to determine the acute effect of an abdominal hypopressive exercise (AHE) on linea alba morphology among women who are primiparous and to compare this effect with that of other common abdominal exercise modalities.

METHODS

A cross-sectional study of 46 women 3 months after first delivery was conducted. B-mode ultrasound imaging of the interrectus distance (IRD) and linea alba distortion was performed 2 cm below (I-point) and above (S-point) the umbilicus and at the mid-point between the umbilicus and xiphoid process (X-point). Images were recorded at rest and during an AHE performed in a supine position, a semi curl-up (SCU), an abdominal drawing-in maneuver (ADIM), and a SCU performed after an initial ADIM (ADIM+SCU).

RESULTS

The SCU exercise narrowed the IRD at the X- and S-points. Compared with SCU, AHE and ADIM widened the IRD at the S- and X-points. No significant differences were found when comparing the IRD at rest, during AHE and during ADIM, but AHE tended to narrow I-point IRD more than ADIM but to widen S-point IRD more than ADIM+SCU. No participant showed linea alba distortion during the AHE or ADIM. When compared, SCU increased the occurrence of distortion with respect to AHE and ADIM. The isolated hypopressive posture did not change the IRD or linea alba distortion.

CONCLUSION

Among women who were postpartum, AHE seemed to narrow IRD below the umbilicus compared with ADIM without either of these 2 modalities generating linea alba distortion, as SCU or ADIM+SCU does. Thus, although no significant differences were found when comparing the IRD at rest and during AHE, the AHE could improve the tensile response of the linea alba without increasing the IRD.

IMPACT

This is believed to be the first study to describe linea alba changes during AHE in women who are postpartum. AHE and ADIM seem to show different effects on infraumbilical IRD. The lack of distortion suggests that linea alba may undergo tensile loading at all levels.

Women’s Experiences with Compliance with Pelvic Floor Home Exercise Therapy and Lifestyle Changes for Pelvic Organ Prolapse Symptoms: A Qualitative Study

In this study, we aimed to investigate women’s experiences with compliance with prescribed pelvic floor muscle exercises (PFMEs) and lifestyle changes 6–12 months after completing an individual pelvic floor physiotherapy program. This study was targeted to understanding factors affecting adherence to PFMEs and lifestyle changes to deal with pelvic organ prolapse (POP) symptoms. We designed this research as a descriptive qualitative study. We conducted this study from December 2016 to September 2017 in Madrid, Spain. Twenty-six women with symptomatic POP selected using a purposive sampling method participated in six focus groups and three one-to-one semi-structured interviews. Three authors coded and inductively analyzed transcript contents with iterative theme development. A thematic analysis revealed three main themes: (1) symptoms change; (2) PFMEs and lifestyle changes performance; and (3) a health practitioner–patient relationship. Women identified as adherent reported improvement in physical symptoms and emotional and general state as a result of the new knowledge achieved. Fear also promoted compliance with performing PFMEs and adopting lifestyle changes. Likewise, PFMEs preference and routine, integration of PFMEs and lifestyle changes into activities of daily living, support guides, therapeutic alliance, individual supervision, follow-up, and feedback were also identified as adherence facilitators. One of the biggest barriers that we identified was responsibility. Compliance with prescribed PFMEs and lifestyle changes can be improved with effective individual, women-centered, and supervised physiotherapy programs reducing symptoms, including exercises aligned with women’s preferences that are easy to integrate in daily living, promoting knowledge and awareness of their condition, providing written or electronic guidelines, with routine follow-up visits offering both positive feedback and clear and consistent messages, and enhancing therapeutic alliance.

Effects of Hypopressive Exercise on Posterior Back Chain Kinematics and Pulmonary Function in Professional Female Basketball Players

CONTEXT

Hypopressive exercise (HE) has been used as an alternative lumbo-pelvic injury prevention program and claimed to be a means of respiratory and flexibility improvement. However, the possible effects of HE on athletic populations and physical performance remain unclear.

OBJECTIVE

Examine the effects of a HE program on posterior back chain kinematics, thoracic mobility, pulmonary function, and lower lumbar pain in female basketball players over an 8-week training period.

DESIGN

Prospective (1) baseline, (2) midpoint (4 wk), and (3) after 8 weeks.

SETTING

Sports field.

PARTICIPANTS

A total of 17 professional female basketball players (mean age 20.7 y, SD: 3.50; body mass index, 21.71, SD: 1.69).

INTERVENTION

Participants performed 8 HE weekly sessions of 30 minutes.

MAIN OUTCOME MEASURES

Back chain kinematics was assessed with the sit and reach and finger to floor test, and back pain was assessed through numerical rating scale. Respiratory parameters were assessed by spirometry and through thoracic mobility.

RESULTS

The analysis of variance revealed significant differences between the 3 measurement periods for thoracic mobility (P > .01); forced expiratory volume in the first second (P < .05) while no statistical differences were found for the rest of spirometry outcomes. Significant differences were also revealed between baseline and after the intervention for the sit and reach test (P > .01), peak expiratory flow (P = .01), and forced expiratory volume in the first 25 seconds (P = .04). Also, significant differences between weeks were found in levels of lumbar pain (P = .003) and the finger to floor test (P = .002).

CONCLUSIONS

These preliminary findings suggest that a HE program can improve posterior back chain and chest wall kinematics as well as lower lumbar pain levels. However, no gains seem to be observed for the majority of pulmonary variables except for peak expiratory flow and forced expiratory volume in the first seconds.

What Influences Women to Adhere to Pelvic Floor Exercises after Physiotherapy Treatment? A Qualitative Study for Individualized Pelvic Health Care

Conservative treatment of pelvic floor dysfunction (PFD) includes therapeutic exercise for pelvic floor muscle (PFM) training or other complementary exercise modalities, such as hypopressive exercises. However, the long-term effectiveness of the conservative treatment depends on a patient's adherence to the exercises and the integration of professional health advice into their daily life. The objective of this study was to establish the adherence experience of women with diagnosed PFD in home-based exercises after an intensive face-to-face physiotherapy treatment. A qualitative study from an interpretive paradigm was developed. Semi-structured individual and group interviews were performed 6 months after finishing individual physiotherapy treatment. The interviews were recorded, fully transcribed and analyzed thematically by creating categories. Thirty-one women were interviewed. The women reported that their adherence to home PFM exercises depended on the exercise program itself, its efficacy, their personal experiences with the exercises, intrinsic factors such as self-awareness or beliefs, and extrinsic factors, such as professional or instrumental feedback. Thus, therapeutic adherence could be more likely with effective physiotherapy programs that include mutually agreed home exercises and simple movements women can build into their daily lives. Improving awareness and knowledge of the pelvic region and the importance of PFM treatment as well as consideration for potential worsening of PFD will also encourage women to adhere to the exercises.

The Main Role of Diaphragm Muscle as a Mechanism of Hypopressive Abdominal Gymnastics to Improve Non-Specific Chronic Low Back Pain: A Randomized Controlled Trial

Background: Chronic low back pain (LBP) has been stated as one of the main health concerns in the XXI century due to its high incidence. Objective: The objective of this study was to determine the effects of an 8-week program of hypopressive abdominal gymnastics (HAG) on inspiratory muscle strength, diaphragm thickness, disability and pain in patients suffering from non-specific chronic LBP. Methods: A total of 40 patients with chronic LBP were randomly divided into two groups. The experimental group carried out an 8-week supervised program of HAG (two sessions/week), whereas the control group did not receive any treatment. Outcomes were measured before and after the intervention, comprising diaphragm thickness during relaxed respiratory activity, maximal inspiratory pressure (PI_max), pain intensity (NRS), pressure pain threshold and responses to four questionnaires: Physical Activity Questionnaire (PAQ), Roland–Morris Disability Questionnaire (RMQ), Central Sensitization Inventory (CSI) and Tampa Scale of Kinesiophobia-11 Items (TSK-11). Results: Statistically significant differences (p < 0.05) were observed for greater thickness of the left and right hemi-diaphragms at inspiration, as well as higher PI_max and decreased NRS, CSI and RMQ scores in the intervention group. After treatment, the increases in the thickness of the left and right hemi-diaphragms at inspiration and PI_max, as well as the decrease in the NRS and RMQ scores, were only predicted by the proposed intervention (R² = 0.118–0.552). Conclusions: An 8-week HAG intervention seemed to show beneficial effects and predicted an increase in diaphragm thickness and strength during inspiration, as well as a reduction in pain intensity, central sensitization and disability, in patients suffering from chronic non-specific LBP with respect to non-intervention.

Are There Any Differences in Abdominal Activation between Women and Men during Hypopressive Exercises?

This study analyzes the effects of hypopressive exercises on the abdominal thickness of healthy subjects and compares the performance between women and men. We conducted a transversal observational study in 98 subjects (63% women). The muscle thickness is analyzed in transversus abdominis, internal oblique, external oblique, and rectus abdominis with ultrasound imaging at rest and during the hypopressive exercise (HE) in supine and standing position. Comparisons between rest and hypopressive exercise are carried out in the two different positions and between women and men. In the supine position, there is a significant activation of the transversus abdominis and internal oblique during hypopressive exercise (p < 0.001), and it is similar in both sexes, the external oblique is only activated significantly by men (p < 0.001) and rectus abdominis had no significant activation (p > 0.05). Our results show that standing transversus abdominis and external oblique significantly increased their thickness during HE with higher effects in men. Internal oblique also increased significantly, but with higher effects in women, and rectus abdominis had no significant increase. Men had similar effects to women during HE, with an activation of the deepest abdominal muscles. The unequal anatomy and the position could explain the different results obtained between the sexes.

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

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.

The Rolf Method of Structural Integration and Pelvic Floor Muscle Facilitation: Preliminary Results of a Randomized, Interventional Study

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.
