Effectiveness of non-pharmacological conservative therapies for chronic pelvic pain in women: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the effectiveness of non-pharmacological, conservative therapies for women with chronic pelvic pain (CPP). DATA SOURCES: A systematic search of electronic databases (Amed, CINAHL, PsycINFO, SportDiscuss, Medline, PubMed, Embase, and Cochrane Central Register of Controlled Trials) was performed in January 2023, and updated in December 2023. STUDY ELIGIBILITY CRITERIA: Randomized controlled trials (RCTs) comparing a non-pharmacological, conservative therapy to inert (e.g., placebo, usual care) or non-conservative (e.g., surgical, pharmacological) treatment were included. Conservative therapies of interest to this review were: multimodal physical therapy, predominantly psychological approaches, acupuncture, and other tissue-based monotherapies (e.g., electrophysical agents, manual stretching). STUDY APPRAISAL AND SYNTHESIS METHODS: All study data were aggregated, and analyses of the included studies were performed. Effects on pain; sexual measures; psychological and physical function; health-related quality of life; symptom severity/bother; pelvic floor muscle function and morphometry; perceived improvement; and adverse events were analyzed. Meta-analyses (random effects model) were conducted using post-intervention scores for data that included similar interventions and outcomes. Standardized mean differences (SMD) were calculated. A narrative summary of findings that could not be included in the meta-analysis is provided. The quality of the evidence was assessed with the PEDro scale and the certainty of evidence with Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria. RESULTS: Of 5776 retrieved studies, 38 RCTs including 2168 women (mean age 35.1±8.6) were included. Meta-analyses revealed that multimodal physical therapy resulted in lower pain intensity compared to inert or non-conservative treatments in both the short (SMD -1.69, 95% CI -2.54,-0.85; high certainty) and intermediate-terms (SMD -1.82, 95% CI -3.13, -0.52; moderate certainty), while predominantly psychological approaches resulted in no difference in pain intensity (SMD -0.18, 95% CI -0.56, 0.20; moderate certainty) and a slight difference in sexual function (SMD -0.28, 95% CI -0.52,-0.04; moderate certainty). The level of evidence regarding the meta-analysis of the effects of acupuncture on pain intensity (SMD 1.08, 95% CI -1.38, 3.54, non-statistically significant results in favor of control treatment) precluded any statement of certainty. A limited number of trials investigated individual tissue-based monotherapies, providing a restricted body of evidence. CONCLUSIONS: This systematic review with meta-analysis revealed that multimodal physical therapy is effective in women with CPP with a high certainty of evidence.

Can pelvic floor muscle function before surgery determine the outcome of surgical treatment of stress urinary incontinence in women?

AIM: The study aimed to determine whether pelvic floor muscle (PFM) function before surgery may correlate with the success of surgical interventions for treating stress urinary incontinence (SUI). Our hypothesis was that addressing identified variables in preoperative rehabilitation could potentially improve surgical outcomes. METHODS: This prospective observational study was conducted at a single center and enrolled women qualified to mid-urethral tape insertion for SUI between 2020 and 2022. Digital palpation and manometry (Peritron™ 9300 V) were used to evaluate PFM function. The following parameters were acquired: vaginal resting pressure, vaginal pressure during maximal voluntary contraction (MVC), the area under the curve during a 10-second MVC, moreover the ability to perform correct PFM contraction, reflexive PFM contraction during cough and relaxation were assessed. All measurements were performed before the surgical treatment and during follow-up assessments at 1, 3, and 6 months postoperatively. The primary endpoint of the study was defined as objective cure, characterized by a negative cough stress test (CST), along with a subjective assessment based on the Urogenital Distress Inventory-6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7). RESULTS: The study involved 57 eligible female participants, all of whom completed the 6-month follow-up. Objective cure was observed in 75.44% of cases, while subjective cure was reported in 33%. There was no association between PFM parameters and surgical outcomes. CONCLUSION: The success of surgical treatment of SUI 6 months postsurgery is not related to preoperative pelvic floor muscle function.

Impact of preoperative pelvic floor muscle function on the success of surgical treatment of pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to identify the potential characteristics of pelvic floor muscles (PFM) in the preoperative assessment that could be associated with post-surgical prolapse severity. We hypothesized that the same variables, if identified, could be addressed in preoperative rehabilitation to improve surgical results. METHODS: This was a single-center prospective observational study that included women who underwent surgical pelvic organ prolapse repair between 2020-2022. Genital prolapse was evaluated according to the Pelvic Organ Prolapse Quantification (POP-Q) system. All the participants underwent a PFM assessment, including a vaginal digital assessment and manometry (Peritron™ 9300 V) before surgery and at 1-, 3-, and 6-month follow-ups. Several PFM variables were recorded: vaginal resting pressure, vaginal pressure during maximal voluntary contraction (MVC), area under the curve during a 10-second MVC, ability to correctly contract the PFMs, and reflexive activation during cough and relaxation. The primary endpoint of the analysis was objective surgical success defined as POP-Q 0 or 1 at the 6-month follow-up. Additionally, a change in pelvic floor muscle function was recorded during postoperative visits. RESULTS: A total of 106 females were included in the study. Fifty-one were lost during the 6-month follow-up, which is a major limitation of the study. None of the examined parameters evaluating PFM were associated with surgical success. No statistically significant difference was found in MVC and PFM endurance before and after surgery. Post-surgery, a significant change was observed in the vaginal resting pressure and the ability to correct PFM activation and relaxation. CONCLUSIONS: Preoperative PFM function is not associated with surgical success 6 months after surgery.

The effects of one-time soft tissue therapy on pelvic floor muscle electromyographic signals in women with urinary incontinence: A randomized intervention trial.

AIMS: To investigate the effects of one-time soft tissue therapy (STT) on pelvic floor muscle (PFM) electromyographic signals in women with stress and/or mixed urinary incontinence. METHODS: An intervention study conducted with 63 women with stress and/or mixed urinary incontinence. Participants were randomly assigned to either the one-time STT group (experimental group) or the control group. The same teaching model for voluntary contraction and relaxation of the PFM was used for all participants. Electromyographic signals from the PFM during functional tasks were the primary clinical outcome measures at baseline and immediately after the intervention. Electromyographic signals were analyzed using root mean square amplitude. RESULTS: There was no significant difference between groups in electromyographic PFM signals in prebaseline rest (mean difference: -0.146 [95% confidence interval (CI): -0.44 to 0.148; p = 0.470]), phasic contractions (mean difference: 0.807 [95% CI: 0.123-1.491; p = 0.459]), tonic contractions (mean difference: 1.06 [95% CI: 0.255-1.865; p = 0.302]), endurance contractions (mean difference: 0.896 [95% CI: 0.057-1.735; p = 0.352]) and postbaseline rest (mean difference: -0.123 [95% CI: -0.406 to 0.16; p = 0.591]) immediately after the one-time STT intervention. CONCLUSION: A one-time STT intervention does not appear to effectively alter electromyographic signal of the PFM in women with urinary incontinence. Due to the limitations of the study, further research is needed to confirm these results.

Not all lasers are the same: a scoping review evaluating laser therapy for vulvodynia.

INTRODUCTION: Lasers are commonly used for treating various vaginal/vulvar conditions. To date, there is to our knowledge no available literature review on the effects of different types of lasers for the treatment of women with vulvodynia, a condition that causes chronic pain in the vulvar area. OBJECTIVES: We sought to review the literature and summarize the existing published evidence regarding the effects of lasers for the treatment of women with vulvodynia. METHODS: A scoping review with a systematic search was conducted that included studies investigating the use of laser treatment in women with vulvodynia. The National Heart, Lung, and Blood Institute Study Quality Assessment Tools were used for the quality assessment. The type of laser, effects on pain and function, and participants' perceived improvement as well as adverse events were analyzed. RESULTS: Eight studies investigating laser therapy were included in the analysis: 1 randomized controlled trial, 5 before-after studies, 1 nonrandomized intervention study, and 1 case report. Several types of laser therapies were identified, ranging from mild noninvasive photobiomodulation to more invasive ablative procedures. Of the 6 studies that included pain outcomes, 3 studies showed statistically significant improvements from baseline to follow-up, and 3 demonstrated a reduction in pain from subjectively interpreted data. Similarly, each of the 2 studies investigating sexual function also reported an improvement (based only on subjective interpretation). Of the 2 studies with a comparison group, neither study was adequately powered to detect between-group differences. Furthermore, 57%-78% of participants reported improvement, with 1 study showing a greater statistically significant improvement in the low-level laser therapy patient group compared to the sham laser group. Outcomes and adverse events varied depending on the type of laser used. CONCLUSIONS: Although these studies demonstrated some benefits of laser therapy for the treatment of vulvodynia, these findings should be interpreted with caution given the scarcity of the included studies that were robust and sufficiently powered. Future research should focus on conducting well-designed randomized controlled trials to evaluate the efficacy of different types of lasers in the treatment of vulvodynia.

Telerehabilitation for persistent Pelvic Girdle Pain within a biopsychosocial framework - A case report.

BACKGROUND: Persistent pregnancy-related pelvic girdle pain (PGP) and the resulting consequences may considerably influence a woman's quality of life. The complexity of this condition requires a whole-person centered approach. In response to COVID-19 outbreak, telerehabilitation has emerged as a promising alternative to traditional in-person visits. PURPOSE: The aim of this report was to present the potential of telerehabilitation for persistent postpartum PGP within the biopsychosocial framework. CASE DESCRIPTION: A 26-year-old female presented with persistent pregnancy-related PGP of 8 months duration after her first vaginal delivery. The video-consults were performed using telerehabilitation platform. The patient received six telerehabilitation consults of 45 min duration over five weeks. Assessment of physical and psychosocial factors, cognitively focused strategies including pain neurophysiology education, sensory-motor remapping exercises, and graded increase of activity were administered. Rehabilitation was divided into the following phases: assessment, desensitization, graded exposure, and supported independence. OUTCOMES: The Pelvic Girdle Questionnaire (PGQ) score was significantly reduced from 72.2 during the assessment to 15.3 at discharge. This change was significantly more substantial than the minimal clinically important change estimated for the PGQ. CONCLUSION: Physiotherapists can utilize telerehabilitation to assist them with enacting appropriate care measures for persistent PGP within a biopsychosocial framework.

Prevalence and factors associated with postpartum pelvic girdle pain among women in Poland: a prospective, observational study.

BACKGROUND: Pelvic girdle pain (PGP) is a type of pregnancy-related lumbopelvic pain. This study aimed to examine the prevalence, severity, and factors associated with postpartum PGP in a selected group of postpartum women in Poland. METHODS: This was a prospective, observational study. In phase 1, 411 women were recruited 24-72 h postpartum. The prevalence of PGP was assessed by a physiotherapist using a series of dedicated tests. Pelvic floor muscle function and presence of diastasis recti were assessed via palpation examination. Age, education, parity, mode of delivery, infant body mass, body mass gain during pregnancy, the use of anesthesia during delivery and were recorded. In a phase 2, 6 weeks postpartum, the prevalence of PGP and its severity were assessed via a self-report. RESULTS: In phase 1 (shortly postpartum), PGP was diagnosed in 9% (n = 37) of women. In phase 2 (6 weeks postpartum), PGP was reported by 15.70% of women (n = 42). The univariable analyses showed a higher likelihood of PGP shortly postpartum in women who declared PGP during pregnancy (OR 14.67, 95% CI 4.43-48.61) and among women with abdominal midline doming (OR 2.05, 95% CI 1.04-4.06). The multivariable regression analysis showed significant associations in women with increased age (OR 1.12, 95% CI 1.01-1.21) and declaring PGP during pregnancy (OR 14.83, 95% CI 4.34-48.72). CONCLUSION: Although the prevalence of postpartum PGP among women in Poland is lower than reported in other countries, it is experienced by almost every tenth women shortly postpartum and every sixth can report similar symptoms 6 weeks later. Age, PGP during pregnancy and abdominal midline doming were associated with experiencing PGP shortly postpartum.

High-Intensity Laser Therapy (HILT) as an Emerging Treatment for Vulvodynia and Chronic Musculoskeletal Pain Disorders: A Systematic Review of Treatment Efficacy.

High-intensity laser therapy (HILT) has been gaining popularity in the treatment of chronic musculoskeletal pain, including vulvodynia. The objective of this study was to critically appraise and synthesize the available evidence on the efficacy of HILT for reducing pain and improving function in vulvodynia and other chronic primary musculoskeletal pain conditions. Electronic databases and the grey literature were searched. Effects on pain intensity, function, and adverse events were assessed. One study investigating HILT in the treatment of vulvodynia and 13 studies on the treatment of chronic musculoskeletal pain were selected. The study assessing vulvodynia showed favorable results for reducing pain. Regarding chronic musculoskeletal pain, 12 out of the 13 studies selected consistently showed that HILT was more effective than the placebo/active comparator for reducing pain and improving function. The available effect sizes for pain showed large to huge effects. Similar effects were observed for function except for two studies showing moderate effects. The GRADE score was moderate. Conclusions: There are insufficient data to support the use of HILT in vulvodynia, but the promising results encourage further research. HILT appears to be effective in musculoskeletal pain conditions. More high-quality studies are needed to identify effective laser protocols.

The Association between Postpartum Pelvic Girdle Pain and Pelvic Floor Muscle Function, Diastasis Recti and Psychological Factors-A Matched Case-Control Study.

There is uncertainty regarding the association between abdominal morphology, pelvic floor function, and psychological factors in women with postpartum pelvic girdle pain (PGP). The aim of this case-control study was to evaluate the differences between women with and without persistent PGP regarding pelvic floor function, diastasis recti, and psychological factors 6−24 weeks postpartum. Pelvic floor manometry, palpation examination of abdominal muscles, the International Consultation on Incontinence Questionnaire Short Form, The Depression, Anxiety and Stress Scale­21, and the Pain Catastrophizing Scale were used. The PGP group presented with lower vaginal resting pressure (p < 0.001), more tenderness (p = 0.018) and impaired voluntary activation of pelvic floor muscles (p ≤ 0.001). Women with pain also had more distortion on the level of the anterior abdominal wall (p = 0.001) and more severe diastasis recti (p = 0.046) when compared to pain-free controls. Lower vaginal resting pressure was the strongest factor explaining PGP (OR 0.702, 95%CI 0.502−0.981). There were no differences in terms of the pelvic floor strength, endurance, severity of urinary incontinence and reported distress between the groups. Women with PGP 6−24 weeks postpartum differ in pelvic floor and abdominal muscle function from the pain-free controls. Vaginal resting pressure may be an important factor in pelvic girdle pain shortly postpartum. Further studies are needed to see a trend in changes over time.

Effect of Manual Therapy Compared to Ibuprofen on Primary Dysmenorrhea in Young Women-Concentration Assessment of C-Reactive Protein, Vascular Endothelial Growth Factor, Prostaglandins and Sex Hormones.

BACKGROUND: The study aimed to assess if manual therapy, compared to ibuprofen, impacts the concentration of inflammatory factors, sex hormones, and dysmenorrhea in young women Methods: Thirty-five women, clinically diagnosed with dysmenorrhea, were included in the study. They were divided into group A-manual therapy (n = 20) and group B-ibuprofen therapy (n = 15). Inflammatory factors such as vascular endothelial growth factor (VEGF), C-reactive protein (CRP), prostaglandin F2α (PGF2α), E2 (PGE2) and sex hormones levels were measured. Dysmenorrhea assessed with the numerical pain rating scale (NPRS), myofascial trigger points, and muscle flexibility were examined before and after the interventions. RESULTS: The difference in the level of 17-ß-estradiol after manual and ibuprofen therapy was significant, as compared to baseline (p = 0.036). Progesterone levels decreased in group A (p = 0.002) and B (p = 0.028). The level of CRP was negatively correlated with sex hormones. Decrease in dysmenorrhea was significant in both groups (group A p = 0.016, group B p = 0.028). Non-significant differences were reported in prostaglandins, VEGF and CRP levels, in both groups. CONCLUSIONS: There were no significant differences in CRP, prostaglandins and VEGF factors after manual or ibuprofen therapy. It has been shown that both manual therapy and ibuprofen can decrease progesterone levels. Manual therapy had a similar effect on the severity of dysmenorrhea as ibuprofen, but after manual therapy, unlike after ibuprofen, less muscles with dysfunction were detected in patients with primary dysmenorrhea.

Association Among Pelvic Girdle Pain, Diastasis Recti Abdominis, Pubic Symphysis Width, and Pain Catastrophizing: A Matched Case-Control Study.

OBJECTIVE: Pregnancy-related pelvic girdle pain (PGP) may persist or occur postpartum and negatively affects women's lives. There is uncertainty regarding the association between the structures of the bony pelvis, diastasis recti abdominis (DRA), pain processing, and PGP and to what extent these factors should be considered during physical therapy. This study aimed to evaluate the differences between women with and without PGP shortly after delivery regarding the separation of a pubic symphysis, DRA, and pain catastrophizing. METHODS: Women diagnosed with PGP 24 to 72 hours after vaginal delivery were matched to pain-free controls according to age and parity. Ultrasound evaluations of diastasis recti (interrecti distance [IRD]) during rest and curl-up task and pubic symphysis (interpubic width) were performed. The Pain Catastrophizing Scale was used to assess the level of catastrophizing. A special Cox regression model was used to fit a conditional logistic regression for a 1:2 matched case-control study. RESULTS: Thirty-five women with clinically diagnosed PGP and 70 matched controls were included in the study. The PGP group had a significantly higher pre-pregnancy body mass index than the control group. After adjusting for body mass index in multiple conditional logistic regression, the interpubic distance (odds ratio = 1.64; 95% CI = 1.22 to 2.20) and IRD during curl-up (odds ratio = 2.01; 95% CI = 1.08 to 3.74) were significantly associated with PGP. Pain catastrophizing and IRD at rest were not associated with PGP in univariable or multivariable analysis. CONCLUSIONS: Pain catastrophizing is similar for women with and without PGP early postpartum. However, the degree of the pubic symphysis and rectus abdominis separation during the curl-up task are positively associated with PGP shortly after delivery. IMPACT: This study indicates that a reconsideration of the way we look at DRA is warranted. The development of a more comprehensive assessment including objective measurements and a biopsychosocial understanding is needed to inform directions for further postpartum physical therapy.

Compliance with gestational weight gain recommendations in a cross-sectional study of term pregnancies - how far reality falls from the standard?

OBJECTIVES: During pregnancy, two aspects are critical in the context of adverse perinatal outcomes (APO): preconception obesity and gestational weight gain. This study aimed to assess compliance with the 2009 IOM guidelines, compare GWG with and without correcting for gestation duration, and observe the relationship between pre-pregnancy BMI and GWG and neonatal birth weight. MATERIAL AND METHODS: This is a cross-sectional study conducted from 2015-2018 at the St. Sophia's Specialist Hospital in Warsaw, Poland. Self-reported pre-pregnancy and predelivery weight were collected. RESULTS: The presented data set amounts to 7820 records. Analysis of weight gain compliance with IOM recommendations showed that only 41-44% (depending on the calculation method) of women had weight gain in accordance with IOM guidelines (22-23% - below; 33-37% - above). Overweight and obese women with diabetes are more likely to comply with IOM than women without diabetes. In contrast, women with normal-weight and underweight with diabetes are less likely to achieve IOM weight gain in pregnancy than women without diabetes. Women who have GWG below recommendations significantly more often gave birth to SGA neonates, and women who exceeded GWG standards significantly more often gave birth to LGA neonates. CONCLUSIONS: Less than half of women had GWG within the recommended norms. Statistically significant differences were found in methods of calculation of GWG, but it was not found clinically significant. Correction for pregnancy duration when calculating GWG reclassifies two percent of patients. We underestimate the risk of crossing the line between overweight and obesity during pregnancy.

Is PREHAB in Pelvic Floor Surgery Needed? A Topical Review.

Pelvic organ prolapse and urinary incontinence affect approximately 6-11% and 6-40% of women, respectively. These pathologies could result from a weakness of pelvic floor muscles (PFM) caused by previous deliveries, aging or surgery. It seems reasonable that improving PFM efficacy should positively impact both pelvic floor therapy and surgical outcomes. Nonetheless, the existing data are inconclusive and do not clearly support the positive impact of preoperative pelvic floor muscle training on the improvement of surgical results. The restoration of deteriorated PFM function still constitutes a challenge. Thus, further well-designed prospective studies are warranted to answer the question of whether preoperative PFM training could optimize surgical outcomes and if therapeutic actions should focus on building muscle strength or rather on enhancing muscle performance.
