Although pregnant women are anecdotally said to "waddle" during gait, researchers have not quantified the kinematics of these gait alterations. The purpose of this study was to examine the effects of pregnancy on thoracic and pelvic kinematics during gait.Data were collected on 29 pregnant subjects in the mid-second and third trimesters and on 40 control women. Three-dimensional kinematic data were collected on subjects walking at their freely-chosen speed. Right foot heel-strike (RHS) and left foot toe-off (LTO) were determined from force plate data. Thoracic and pelvic angles at RHS, step width, mediolateral translation of the C7 and L4 vertebrae, and the ranges of motion (ROMs) of the thorax and pelvis over the gait stride were determined. A series of MANCOVAs were performed with trimester (second, third, and control) as the independent variable and velocity as the covariate (α=0.05). Post-hoc analyses were performed when appropriate.Increased lateral translation of the C7 and L4 vertebrae (third trimester>second trimester>control, p<0.05) was noted, accompanied by an increased step width in the third trimester (p=0.03). At heel strike, pregnant women had greater thoracic extension (third trimester>second trimester>control, p<0.05) and greater anterior pelvic tilt (third trimester>control; p<0.05). Sagittal plane thoracic ROM was less in the third trimester compared to controls (p<0.01).Pregnant women demonstrated a lateral shifting of the body during gait, which accompanied a greater step width. The increased thoracic extension and anterior pelvic tilt, along with decreased sagittal plane ROM are likely adaptations to increased abdominal size.Copyright © 2014 Elsevier Ltd.

As foot constitutes the base of support for the whole body, the pregnancy-related anthropometric changes can result in adaptive plantar pressure alterations. The present study aimed to investigate how pregnancy affects foot loading pattern in gait, and if it is related to body adjustments to growing foetus that occur in the course of pregnancy.

To characterize the association between thoracic (T) and lumbar (L) spinal curvature and pelvic floor (PF) symptoms (pelvic organ prolapse, urinary incontinence [UI], fecal incontinence [FI]).

The purpose of this study was to assess the prevalence of postural changes in women who had urinary incontinence (UI) with myofascial dysfunction (MD) and women who had UI without MD in the pelvic floor muscles (PFM).

This study sought to characterize central sensitization further among women with chronic pelvic pain by identifying temporal summation using a cotton-tipped applicator test that can be used at the bedside.A total of 36 women (18 with chronic pain and allodynia; 18 without pain) were recruited. Both groups were randomly assigned to receive 3 strokes of a benign stimulus on the abdomen at differing frequencies: 10, 30, or 100 seconds. Each group included 6 women. Pain was assessed using a rating scale of 1 to 10. Data were analyzed using the multivariate approach to repeated measures analysis of variance.The pattern of pain scores differed significantly between women with and without chronic pain (P = 0.002). Women with chronic pelvic pain and allodynia showed a statistically significant increase in pain with successive strokes of the cotton-tipped applicator (P = 0.012 for stroke 1 vs. 2, P = 0.026 for stroke 2 vs. 3, and P = 0.005 for stroke 1 vs. 3).Women with chronic pelvic pain and allodynia showed significant worsening of pain with successive strokes of a cotton-tipped applicator. This finding indicates that pain wind-up and central sensitization are present in women with chronic pelvic pain and allodynia. Identification of summation is further evidence of neuroplasticity, which is helpful in innovative therapies for chronic pelvic pain.Copyright © 2019 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.

The aim of this study was to assess pelvic floor muscle (PFM) strength in different body positions in nulliparous healthy women and its correlation with sexual activity.Fifty healthy nulliparous women with mean age of 23 years were prospectively studied. Subjective evaluation of PFM was assessed by transvaginal digital palpation (TDP) of anterior and posterior areas regarding the vaginal introitus. A perineometer with inflatable vaginal probe was used to assess the PFM strength in four different positions: supine with extended lower limbs (P1); bent-knee supine (P2); sitting (P3); standing (P4).Physical activity, 3 times per week, was reported by 58% of volunteers. Sexual activity was observed in 80% of women and 82% of them presented orgasm. The average body mass index (BMI) was 21.76 kg/m2, considered as normal according World Health Organization (WHO). We observed that 68% of volunteers were conscious about the PFM contraction. TDP showed concordance of 76% when anterior and posterior areas were compared (p = 0.00014). There was not correlation between PFM strength and orgasm in subjective evaluation. The PFM strength was significantly higher in standing position when compared with the other positions (p < 0.000). No statistical difference was observed between orgasm and PFM strength when objective evaluations were performed.There was concordance between anterior and posterior areas in 76% of cases when subjective PFM strength was assessed. In objective evaluation, higher PFM strength was observed when volunteers were standing. No statistical correlation was observed between PFM strength and orgasm in nulliparous healthy women.

In 2004, Patricia Skilling developed a new squatting-based pelvic floor rehabilitation method based on strengthening the three reflex pelvic muscles and ligaments hypothesized to control the closure and micturition reflexes. We adapted these methods to test our hypothesis that day/night enuresis was due to the inability of these muscles/ligaments to control an inappropriately activated micturition reflex.The trial commenced as a randomized control trial to be conducted over 4 months, but was converted to a prospective trial at 4 weeks by order of the Ethics Committee. A total of 48 children, 7.6 ±2.5 years, 34 females, 14 males, had strictly supervised exercises twice daily, 10 squats, 10 bridge, fitball exercises involving proprioception exercises with surface perineal electromyogram (EMG) once a week.Eligibility criteria were daytime urine leakage plus night-time bedwetting. Exclusion criterion was refusal to sign consent forms. Assessment was done by intention to treat. The criterion for cure was complete dryness.At 1 review (4 weeks) 12/24 in the treatment group reported total cure of wetting; 41/48 children (86%) were cured of both daytime/nighttime enuresis (p <0.001) at 4 months. There were no adverse events. Secondary outcomes were concomitant cure of constipation, fecal incontinence, urinary retention as predicted by the underlying integral theory of incontinence.We believe our methods accelerated normal childhood strengthening of muscles/ligaments which control inappropriate activation of the micturition reflex which we hypothesize is the basis for daytime/nighttime enuresis. This is a simple treatment, needs diligent application and validation by others.Copyright by Polish Urological Association.

To evaluate the effect of ankle positions on pelvic floor muscles in women. Multiple databases were searched from inception-July 2017. Study quality was rated using the grading of recommendations, assessment, development, and evaluation system and the "threats to validity tool". Four studies were eligible for inclusion. Meta-analysis revealed significantly greater resting activity of pelvic floor muscles in neutral ankle position (-1.36 (95% CI -2.30, -0.42)  =  0.004) and induced 15° dorsiflexion (-1.65 (95% CI -2.49, -0.81)  =  0.0001) compared to induced 15° plantar flexion. Significantly greater maximal voluntary contraction of pelvic floor was found in dorsiflexion compared to plantar flexion (-2.28 (95% CI -3.96, -0.60)  =  0.008). Meta-analyses revealed no significant differences between the neutral ankle position and 15° dorsiflexion for either resting activity (0.30 (95% CI -0.75, 1.35)  =  0.57) or maximal voluntary contraction (0.97 (95% CI -0.77, 2.72)  =  0.27). Pelvic floor muscle-training for women with urinary incontinence could be performed in standing with ankles in a neutral position or dorsiflexion to facilitate greater maximal pelvic floor muscle contraction. As urethral support requires resting contraction of pelvic floor muscles, decreased resting activity in plantar flexion identified in the meta-analysis indicates that high-heel wearers with urinary incontinence might potentially experience more leakage during exertion in a standing position. Implications for rehabilitation Pooled analyses revealed that maximal voluntary contraction of pelvic floor muscle is greater in induced ankle dorsiflexion than induced plantar flexion. As pelvic floor muscle strengthening involves achieving a greater maximal voluntary contraction, pelvic floor muscle training for women with stress urinary incontinence could be performed in standing either with ankles in a neutral position or dorsiflexion. Decreased resting activity in plantar flexion identified in the meta-analysis indicates that high-heel wearers with stress urinary incontinence might potentially experience more leakage during exertion in a standing position. Women with stress urinary incontinence should be advised to wear flat shoes instead of high-heels and should be cautioned about body posture and ankle positions assumed during exercise and daily activities.

To examine the relationships between prenatal physical activity and prenatal and postnatal urinary incontinence (UI).

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.

Introduction: The aim of the study was to assess the influence of the implemented therapeutic programme, which consisted of body posture correction and of change of habits, on the pelvic floor muscle function in women with stress urinary incontinence. Material and methods: The 60 women were randomly divided into two groups: the study population and the clinical control group (subjects received envelopes with numbers of the group: 1- study population aged 38.3 ± 5.54, 2- clinical control group aged 35.5 ± 4.7. We used the following research methods: A personal questionnaire with subjects’ demographics and with questions related to the type of work, physical activity, childbirths and any issues related to the pelvic floor (pre-test), Pelvic floor muscle assessment with the use of the PERFECT Scheme and the Oxford scale palpation examination, sEMG with intravaginal electrode and manometry with an intravaginal probe—pre-test and post-test. Subjective assessment of body posture in the sagittal plane according to the McKenzie methodology. Results: In both groups, VRP (resting vaginal pressure) and resting PFM tension were significantly reduced. The strength and endurance of PFM, tension during MVC and VSP (intravaginal pressure during contraction) increased, with no difference between the groups. SUI decreased significantly, and quality of life improved significantly in both groups. Conclusions: Education of the pelvic floor and changing habits significantly affected the activity of PFM and improved the quality of life in the group of patients with SUI. The posture correction therapy with manual therapy and stretching exercises did not increase this effect.

The aim of this study was to evaluate the impact of Global Postural Re-education (GPR) on stress urinary incontinence symptoms and to compare it to Pelvic Floor Muscle Training (PFMT).Fifty-two women with stress urinary incontinence were distributed into two groups: Group 1 (G1) was submitted to weekly sessions of GPR for three months and Group 2 (G2) performed Pelvic Floor Muscle Training four times a week for three months. Patients were evaluated through the King's Health Questionnaire, a three-day voiding diary including daily pad use and a Functional Evaluation of the Pelvic Floor (FEPF), before treatment (T0), at the end of treatment (T1) and six months after treatment (T2).The number of leaking episodes dropped significantly in both groups at the end of treatment and at six months follow-up, with a significantly greater decrease in G1. Daily pad use dropped significantly in both groups. At the end of treatment, 72% of the patients in G1 and 41% of the patients in G2 needed no pads and at six-month follow-up, 84% and 50%, respectively. FEPF improved significantly in both groups, with no significant difference between the groups (P=0.628). The King's Health Questionnaire demonstrated significant improvement in both groups and in all domains. The GPR group presented higher adherence to treatment, with no dropouts.GPR could represent an alternative method to treat stress urinary incontinence in women, should the results be long lasting.Copyright © 2010 Elsevier Ireland Ltd.

Hypopressive exercise (HE) can be viewed as a mind-body activity, characterized by the integration of breath control and stretching postures. Proponents of HE claim that this type of training can offer potential therapeutic or health benefits. To date, there is no existing comprehensive published overview on HE. This scoping review aims to map and summarize the current literature reporting data on HE and identify key knowledge gaps and future research directions. This review considered studies that report on the immediate, short-, or long-term practice of HE regardless of condition, sex, age, and/or level of practice or physical condition. Any context or setting was considered for inclusion. This review was performed in accordance with the methodological framework proposed by the Joanna Briggs Institute and by Arksey and O'Malley. MEDLINE, CINAHL, SPORTDiscus, Scopus, and Web of Science were searched from inception up to July 2023. Literature was mapped following the Patterns-Advances-Gaps-Evidence for Practice Recommendations framework to identify patterns and inform practice. In total, 87 studies were identified that reported on the following themes: (1) therapeutic application of a short- or long-term HE programs (= 56); (2) physiologic and physical responsiveness to a short- or long-term HE programs (= 22); (3) psychologic and behavioral response to a short-term HE program (= 14); and (4) acute or immediate physiological responses (= 21). Literature gaps included poor methodological design, incomplete reporting of intervention, lack of male participants, and exploration of muscle groups distinct from the pelvic floor and abdominal muscles. There is a need for high-quality randomized controlled trials, adherence to reporting guidelines on exercise, and the use of active control groups to verify clinical significance, the dose response, and health applications of HE.

Background: As the effectiveness on stress urinary incontinence (SUI) prevention of pelvic floor muscle training (PFMT) for pregnant women has been inconclusive, we are planning to conduct a trial to evaluate a video program designed for prevention of SUI developed through combining PFMT with global postural reeducation (GPR). Methods: As a randomized controlled trial, eligible participants will be randomized (1:1) into an exercise group and a control group to perform PFMT regularly following video guidance or with no intervention, respectively. The experimental stage will be from the 16th gestation week (GW) to the 12th month postpartum, with eight appointments at the 16th, 28th, 37th GW, delivery, the 6th week and the 3rd, 6th, and 12th month postpartum. Data will be collected regarding urinary leakage symptoms, the stress test, the modified Oxford Scale, pelvic floor ultrasound, perineal laceration classification at delivery, neonatal Apgar score, and questionnaires (PISQ-12, ICIQ-UI SF, I-QOL, OABSS). The primary outcome is the occurrence of the symptomatic SUI and positive stress test at the 6th week postpartum. Discussion: This protocol is anticipated to evaluate the efficacy of the intervention via video app for the design of a future randomized control trial (RCT). Trial registration: The trial has been registered at Chinese Clinical Trial Registry (registration number: ChiCTR2000029618).

Background: There is a risk of pelvic floor dysfunction (PFD) from baby delivery. Many clinical guidelines recommend pelvic floor muscle training (PFMT) as the conservative treatment for PFD because pelvic floor muscles (PFMs) play a crucial role in development of PFD. However, there is disagreement about the method and intensity of PFM training and the relevant measurements. To pilot the study in PFM training, we designed a Pelvic Floor Workout (PEFLOW) for women to train their pelvic through entire body exercises, and we planned a trial to evaluate its effectiveness through comparing the outcomes from a group of postpartum women who perform PELFLOW at home under professional guidance online with the control group. Methods/design: The randomized controlled trial was projected to be conducted from November 2021 to March 2023. A total of 260 postpartum women would be recruited from the obstetrics departments of the study hospital and women would be eligible for participation randomized into experimental or control groups (EG/CG) if their PFM strength are scaled by less than Modified Oxford grading Scale (MOS) to be less than grade 3. Women in EG would perform a 12-week PEFLOW online under the supervision and guidance of a physiotherapist, while women in CG would have no interventions. Assessments would be conducted at enrollment, post intervention (for EG) or 18th to 24th week postpartum (for CG), and 1 year postpartum. Assessment would be performed in terms of pelvic floor symptoms, including MOS, cough stress test, urinary leakage symptoms, pelvic organ prolapse quantitation (POP-Q), and vaginal relaxation, clinic examinations including Pelvic floor electrophysiological test, Pelvic floor ultrasound and Spine X-ray, overall body test including trunk endurance test, handgrip test, body composition test, and questionnaires including International Physical Activity Questionnaire Score-Short Form(IPAQ-SF), Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20), Pelvic Floor Impact Questionnaire-7 (PFIQ-7), the 6-item Female Sexual Function Index (FSFI-6), and the Pittsburgh Sleep Quality Index (PSQI). Primary analysis will be performed to test our main hypothesis that PEFLOW is effective with respect to strengthen PFM strength. Discussion: This trial will demonstrate that pelvic floor-care is accessible to most women and clinical practice on PFD may change relevantly should this study find that Online PEFLOW approach is effective to improve PFMs. Trial registration: ClinicalTrials.gov, NCT05218239.
