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

OBJECTIVE: To evaluate the effectiveness of nonpharmacological conservative therapies for women with 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 comparing a nonpharmacological conservative therapy to inert (eg, placebo, usual care) or nonconservative (eg, 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 (eg, 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 postintervention scores for data that included similar interventions and outcomes. Standardized mean differences 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 Physiotherapy Evidence Database scale and the certainty of evidence with Grading of Recommendations, Assessment, Development, and Evaluations criteria. RESULTS: Of 5776 retrieved studies, 38 randomized controlled trials 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 nonconservative treatments in both the short (standardized mean difference -1.69, 95% confidence interval -2.54, -0.85; high certainty) and intermediate-terms (standardized mean difference -1.82, 95% confidence interval -3.13, -0.52; moderate certainty), while predominantly psychological approaches resulted in no difference in pain intensity (standardized mean difference -0.18, 95% confidence interval -0.56, 0.20; moderate certainty) and a slight difference in sexual function (standardized mean difference -0.28, 95% confidence interval -0.52, -0.04; moderate certainty). The level of evidence regarding the meta-analysis of the effects of acupuncture on pain intensity (standardized mean difference 1.08, 95% confidence interval -1.38, 3.54, nonstatistically 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. CONCLUSION: This systematic review with meta-analysis revealed that multimodal physical therapy is effective in women with chronic pelvic pain with a high certainty of evidence.

Are pelvic pain and increased pelvic floor muscle tone associated in women with persistent noncancer pelvic pain? A systematic review and meta-analysis.

BACKGROUND: The association between pelvic pain and pelvic floor muscle (PFM) tone in women with persistent noncancer pelvic pain (PNCPP) is unclear. AIM: To synthesize the evidence of the association between pelvic pain and PFM tone in women with PNCPP. METHODS: A systematic review was conducted via MEDLINE, Emcare, Embase, CINAHL, PsycINFO, and Scopus to identify relevant studies. Studies were eligible if pelvic pain and PFM tone outcome measures were reported among women aged >18 years. The National Heart, Lung, and Blood Institute's Quality Assessment Tool for Observational Cohort and Cross-sectional Studies was used to assess study quality. Studies were pooled by assessment of PFM tone via a random effects model. Associations between the presence of pelvic pain and PFM tone were assessed with odds ratio (OR), while linear associations were assessed with Pearson or Spearman correlation. OUTCOMES: Pelvic pain measures (intensity, threshold, and frequency) and resting PFM tone in women with PNCPP, as evaluated by any clinical assessment method or tool. RESULTS: Twenty-four studies were included in this review. The presence of pelvic pain was significantly associated with increased PFM tone as assessed by digital palpation (OR, 2.85; 95% CI, 1.66-4.89). Pelvic pain intensity was inversely but weakly associated with PFM flexibility when evaluated through dynamometry (r = -0.29; 95% CI, -0.42 to -0.17). However, no significant associations were found between pelvic pain and PFM tone when measured with other objective assessment methods. CLINICAL IMPLICATIONS: Pelvic pain and increased PFM tone may not be directly associated; alternatively, a nonlinear association may exist. A range of biopsychosocial factors may mediate or moderate the association, and clinicians may need to consider these factors when assessing women with PNCPP. STRENGTHS AND LIMITATIONS: This review was reported according to the PRISMA guidelines. All possible findings from relevant theses and conference abstracts were considered in our search. However, nonlinear associations between pelvic pain and increased PFM tone were not assessed as part of this review. CONCLUSION: Pelvic pain may be linearly associated with increased PFM tone and decreased PFM flexibility when measured with digital palpation or dynamometry; however, this association was not observed when other aspects of PFM tone were assessed through objective methods. Future studies are required using robust assessment methods to measure PFM tone and analyses that account for other biopsychosocial factors that may influence the association.

A systematic review of diagnostic tests to detect pelvic floor myofascial pain.

INTRODUCTION AND HYPOTHESIS: Myofascial pain arising from pelvic floor muscles occurs in women with vaginismus, interstitial cystitis and endometriosis but is often overlooked. The aim is to examine alternative diagnostic tests to detect pelvic floor myofascial pain compared with standardized vaginal palpation of pelvic floor muscles as the reference test. METHODS: A systematic review was prospectively conducted (PROSPERO-CRD42020183092) according to PRISMA guidelines. Databases searched included Ovid Medline 1946-, Embase 1957-, Scopus 1960-, Cochrane Combined, Clinical trials, Google Scholar (top 200 articles), Web of Science, TRIP, BIOSIS, DARE, CINHAL, EmCare, PEDro, ProQuest and EBSCOhost up to July 2020. Articles were independently screened by two authors and assessed for bias using QUASDAS-2 tool. RESULTS: A total of 26,778 articles were screened and 177 were selected for full text review, of which 5 were selected for final analysis. Five studies included 9694 participants of which 1628 had pelvic floor myofascial pain. Only one study reported data to calculate sensitivities and specificities of the index test, which utilized a score of > 40 on the Central Sensitization Inventory to detect women with pelvic floor myofascial pain and revealed a sensitivity of 34.8% and a specificity of 84.9% compared to the reference test. CONCLUSIONS: This systematic review did not reveal any diagnostic test superior to the pre-defined reference test. There is a lack of consensus on the definition of pelvic floor myofascial pain and a lack of a validated diagnostic criteria which must be addressed to progress with meaningful research in this field.

Reduced pain thresholds and signs of sensitization in women with persistent pelvic pain and suspected endometriosis.

INTRODUCTION: Endometriosis is a gynecological disorder that may cause considerable pelvic pain in women of fertile age. Determining pain mechanisms is necessary in order to optimize the treatment of the disease. The objective of the study was to evaluate pain thresholds in women with persistent pelvic pain with and without confirmed endometriosis, and healthy, unaffected controls, and analyze how pain thresholds in these cohorts related to duration of pelvic pain, quality of life, and symptoms of anxiety and depression. MATERIAL AND METHODS: Pain thresholds for heat, cold and pressure were assessed with quantitative sensory testing on six locations on a reference group of 55 healthy women and on 37 women with persistent pelvic pain who had been admitted for diagnostic laparoscopy on the suspicion of endometriosis. Validated instruments were applied to assess quality of life and symptoms of anxiety and depression. Data were analyzed by means of uni- and multivariate analysis of variance and Spearman's rank-order correlation. RESULTS: The women with persistent pelvic pain had significantly lower pain thresholds compared with the reference women. In the women with pain, no differences were observed in pain thresholds between women with (n = 13) and women without (n = 24) biopsy-proven endometriosis. The duration of pelvic pain correlated significantly positively with reduced pain thresholds, ie, the longer the duration, the more sensitization. In the persistent pelvic pain group, pain thresholds for heat correlated significantly with the Short Form Health Survey 36 dimension of bodily pain, and thresholds for cold correlated with Short Form Health Survey 36 bodily pain and with symptoms of depression. CONCLUSIONS: Our results showed widespread alterations in pain thresholds in women with persistent pelvic pain that are indicative of central sensitization and a time-dependent correlation. Women with pelvic pain and suspicion of endometriosis should probably be treated more thoroughly to prevent or at least minimize the concomitant development of central sensitization.

Psychological interventions for endometriosis-related symptoms: a systematic review with narrative data synthesis.

Endometriosis impacts the physical, psychological and quality of life domains of women. Despite the medical and/or surgical management of endometriosis, the presence of persistent pelvic pain and psychological distress often continues, suggesting a role for psychological interventions in treatment planning. The present study aimed to conduct the first systematic review, with narrative data synthesis, on psychological interventions for endometriosis-related symptoms. The study also aimed to determine the effectiveness of current interventions in resolving psychological and pain-related loss of function associated with endometriosis and to identify gaps in the literature requiring further research. A total of 15,816 studies were retrieved through database searching and handsearching, with two researchers identifying 11 full-text studies that met inclusion criteria. Three studies of 'moderate' quality were identified, although the overall quality of studies was found to be 'weak', with a 'high' risk of bias. The findings regarding the effectiveness of psychological interventions for endometriosis-related symptoms remain inconclusive. Further research into psychological interventions for women with endometriosis that employ evidence-based protocols with high intervention integrity is recommended.

Empowered management for pelvic pain: The experiences of women with persistent pelvic pain participating in an online self-directed self-management program while they wait for interprofessional care.

BACKGROUND: Persistent pelvic pain is pain sensed in or around the pelvis and is often associated with negative cognitive, behavioral, sexual, and emotional consequences. The lack of interprofessional persistent pelvic pain management programs that address the complex interplay of biopsychosocial factors result in lengthy wait times and negative health outcomes. Limited access to evidence informed self-management educational resources contributes to poor coping strategies. Evidence shows that self-management education and strategies support patients while they wait for care. However, very few studies explore the patient's lived experience of participating in an online educational program designed for persistent pelvic pain. OBJECTIVES: This study aims to understand the experience of women with persistent pelvic pain participating in an online, self-management education program ("Pelvic Pain Empowered Management" program) while awaiting care at an interprofessional pelvic pain clinic. DESIGN: A descriptive qualitative approach was used to explore the experiences of women participating in an online educational program designed for cis women with persistent pelvic pain. METHODS: We conducted semi-structured interviews with 11 women, transcribed the data verbatim using NVivo software (NVivo 12, QSR International Pty Ltd.), and analyzed inductively using previously established methods. RESULTS: We identified four main themes relevant to women's experiences of the program: (1) the program shaped expectations around upcoming pelvic pain appointments, (2) the program content is relevant and resonates with people with lived experience of persistent pelvic pain, (3) the program enhanced understanding of persistent pelvic pain, and (4) the program empowered people with skills and strategies to better manage their persistent pelvic pain. CONCLUSION: Our findings highlight how self-directed online patient education can be leveraged while persistent pelvic pain patients wait for care to support them in setting expectations around care and in engaging in pain self-management.

The accessibility of pelvic health physiotherapy for adolescents with persistent pelvic pain: a qualitative framework analysis.

BACKGROUND: Physiotherapy, with a specific focus on pelvic health, is one service used in the multidisciplinary management of adolescent persistent pelvic pain (PPP). However, there has been little investigations into the accessibility of physiotherapy for adolescents with PPP. OBJECTIVE: This qualitative study aimed to detail the experiences of adolescents with PPP accessing a tertiary hospital physiotherapy service. METHODS: Two focus groups included six adolescent females diagnosed with PPP that had either a) been referred and attended the physiotherapy clinic (n = 5), or b) been referred to physiotherapy but yet to attend their appointment (n = 1 plus one support person). Focus group transcripts were deductively thematically analyzed according to four domains from the patient-centered healthcare accessibility framework. RESULTS: The domain of 'Approachability and ability to perceive' was impacted by limited information and poor patient health literacy. 'Acceptability and ability to seek' was hindered by adolescent mental health struggles and failures of previous PPP management. 'Availability and accommodation, and ability to reach' was influenced by lengthy referral processes, and reliance on familial support for transport. 'Acceptability and ability to engage' was facilitated by engaging clinicians and group environments, however, adolescents became dependent on physiotherapy for pain management. CONCLUSION: Physical, social, and environmental factors influence the accessibility of physiotherapy for adolescents with PPP. Healthcare services should consider the specific needs of adolescents with PPP for optimizing accessibility.

A cross-sectional study of traditional Chinese medicine practitioner's knowledge, treatment strategies and integration of practice of chronic pelvic pain in women.

BACKGROUND: Chronic pelvic pain (CPP) in women is persistent, intermittent cyclical and non-cyclical lower abdominal pain, lasting for more than 6 months. Traditional Chinese Medicine (TCM) is a popular treatment option for women's health conditions, but little is known about how treatment for CPP is delivered by TCM practitioners. The aim of this survey was to explore practitioners understanding and treatment of women with CPP, and how they integrate their management and care into the health care system. METHOD: An online cross-sectional survey of registered TCM practitioners in Australia and New Zealand between May and October 2018. Survey domains included treatment characteristics (e.g. frequency), evaluation of treatment efficacy, referral networks, and sources of information that informed clinical decision making. RESULTS: One hundred and twenty-two registered TCM practitioners responded to this survey, 91.7% reported regular treatment of women with CPP. Treatment decisions were most-often guided by a combination of biomedical and TCM diagnosis (77.6%), and once per week was the most common treatment frequency (66.7%) for acupuncture. Meditation (63.7%) and dietary changes (57.8%) were other commonly used approaches to management. The effectiveness of treatment was assessed using multiple approaches, most commonly pain scales, (such as the numeric rating scale) and any change in use of analgesic medications. Limitations to TCM treatment were reported by over three quarters (83.7%) of practitioners, most commonly due to cost (56.5%) and inconvenience (40.2%) rather than safety or lack of efficacy. Sources informing practice were most often Integration within the wider healthcare system was common with over two thirds (67.9%) receiving referrals from health care providers. CONCLUSION: TCM practitioners seeing women with various CPP symptoms, commonly incorporate both traditional and modern diagnostic methods to inform their treatment plan, monitor treatment progress using commonly accepted approaches and measures and often as a part of multidisciplinary healthcare for women with CPP.

Peripheral, Central, and Cross Sensitization in Endometriosis-Associated Pain and Comorbid Pain Syndromes.

Endometriosis-associated pain and the mechanisms responsible for its initiation and persistence are complex and difficult to treat. Endometriosis-associated pain is experienced as dysmenorrhea, cyclical pain related to organ function including dysuria, dyschezia and dyspareunia, and persistent pelvic pain. Pain symptomatology correlates poorly with the extent of macroscopic disease. In addition to the local effects of disease, endometriosis-associated pain develops as a product of peripheral sensitization, central sensitization and cross sensitization. Endometriosis-associated pain is further contributed to by comorbid pain conditions, such as bladder pain syndrome, irritable bowel syndrome, abdomino-pelvic myalgia and vulvodynia. This article will review endometriosis-associated pain, its mechanisms, and its comorbid pain syndromes with a view to aiding the clinician in navigating the literature and terminology of pain and pain syndromes. Limitations of our current understanding of endometriosis-associated pain will be acknowledged. Where possible, commonalities in pain mechanisms between endometriosis-associated pain and comorbid pain syndromes will be highlighted.

Treatment strategy for postoperative persistent pain of endometriosis / 대한산부인과학회지

OBJECTIVE: This study was designed to establish the treatment strategy on postoperative persistent pain of endometriosis. METHODS: During a 12-month period from March 2000 to February 2001, 62 patients had postoperative persistent pelvic pain. 62 patients of them were treated with GnRH analogue for 6 months. If they were not responsive to those treatment, It were recommended high dose progesterone treatment for 6 months after trigger point injection to differentiate from trigger point pain. and then for remained pain, Nonsteroidal antiinflammatory drugs (NSAIDs) and tricyclic antidepressants (TCAs) were supplied for 6 months. Finally, contineously remained pelvic pain was treated by mistletoe extract. RESULTS: 62 patients had a postoperative persistent pelvic pain. GnRH analogue were supplied to 62 patients, and then 23 patients had persistent pain. These 23 patients undertook lidocaine injection on trigger point to differentiate from trigger point pain. Two patients were responsive to injection. Remained 21 patients were treated with high dose progesterone for 6 months. Thereafter unresponded 14 patients were supplied with NSAIDs and TCAs. Finally, remained 5 patients that were uncontrolled with previous treatments were injected with mistletoe extract. Three patients were controlled with mistletoe extract. CONCLUSION: Most of persistent pain after laparoscopic operation of endometriosis were successfully controlled by sequential treatment of GnRH analogue, trigger point injection, high dose progesterone, NSAIDs and TCAs, and mistletoe extract injection.
