Pelvic floor myofascial pain severity and pelvic floor disorder symptom bother: is there a correlation?

Younger Age Is Associated With Pelvic Floor Muscle Dysfunction in Women With Urinary Symptoms

IMPORTANCE

Recent articles have highlighted the existence of pelvic floor myofascial dysfunction in women presenting with pelvic floor disorders.

OBJECTIVE

The aim of the study was to evaluate whether younger age is associated with pelvic floor muscle dysfunction in women with lower urinary tract symptoms, including urinary urgency, frequency, nocturia, and urinary incontinence.

STUDY DESIGN

This retrospective cohort study included women seeking an initial outpatient urogynecology evaluation for urinary symptoms from 8/2018 to 2/2022. The primary outcome was the presence of pelvic floor muscle dysfunction, defined as a diagnosis of levator myalgia/spasm. Multivariable logistic regression was used to evaluate the association.

RESULTS

Four hundred twenty-one women with lower urinary tract symptoms were included, and 115 (27.3%) were diagnosed with pelvic floor muscle dysfunction. Women with pelvic floor dysfunction were 13 years younger, less likely to report any incontinence (60% vs 71.9%, P = 0.026) and urgency incontinence (8.7% vs 17.3%, P = 0.04). There was no difference in reported urgency, frequency, or nocturia. Women with pelvic floor dysfunction were more likely to report dysuria (19.1% vs 9.5%, P = 0.012), dyspareunia (39% vs 7.5%, P < 0.001), vulvodynia (11.3% vs 2.3%, P < 0.001), and pelvic pain (25.2% vs 7.2%, P < 0.001). The odds of pelvic floor muscle dysfunction in women <40 years old was 2.34 times greater than women ≥40 years old, after adjusting for other factors (adjusted odds ratio 2.341, 95% confidence interval [1.102, 4.972]).

CONCLUSIONS

Younger women with lower urinary tract symptoms were significantly more likely to have pelvic floor muscle dysfunction compared to older women with similar symptoms, even after controlling for other associated characteristics.

Pelvic myofascial pain is associated with restriction of sexual activity in women with pelvic pain: a cross-sectional study

Background Dyspareunia and restriction of sexual activity are often reported by patients with chronic pelvic pain, but less is known about which conditions or factors contribute most to these symptoms. Methods This is a cross-sectional study of consecutive new patients who presented to a chronic pelvic pain and endometriosis referral clinic between January 2013 and December 2015. Patients completed a detailed questionnaire prior to their first visit and underwent a comprehensive standardised pelvic examination at their first visit. Patients were grouped according to description of sexual activity as 'normal activity without pain', 'normal activity but painful', 'severely restricted by pain', or 'absent due to pain.' Primary outcome was restriction of sexual activity due to pain. Multinomial logistic regression was performed with 'normal activity without pain' group as reference category and adjusted for age, depression, history of endometriosis, and pelvic myofascial pain. Results Over half of the 187 patients with chronic pelvic pain described severely restricted (n =75, 40.1%) or absent (n =21, 11.2%) sexual activity due to pain. Pelvic myofascial pain was highly prevalent in this population and pelvic myofascial tenderness score was associated with higher odds of sexual activity that was severely restricted by pain (OR 1.05, 95% CI 1.01-1.09, P =0.006) or absent due to pain (OR 1.09, 95% CI 1.04-1.13, P Conclusion Dyspareunia and sexual dysfunction are highly prevalent among patients with chronic pelvic pain, and pelvic myofascial pain is strongly associated with restriction of sexual activity due to pain.

Myofascial pelvic pain: the forgotten player in chronic pelvic pain

PURPOSE OF REVIEW

In this review article, we discuss myofascial-related chronic pelvic pain, pathophysiology, symptomology, and management options.

RECENT FINDINGS

Despite high prevalence of myofascial pelvic pain, screening is not routinely performed by providers. Treatment modalities include pelvic floor physical therapy, pelvic floor trigger point injections with anesthetics or botulinum toxin A and cryotherapy. Other adjunct modalities, such as muscle relaxants and intravaginal benzodiazepines, are used, but data regarding their effectiveness is sparse.

SUMMARY

Myofascial pelvic pain is an important, though overlooked component of chronic pelvic pain. Multimodal, multidisciplinary approach including patient education, pelvic floor physical therapy, and trigger point injections is the mainstay of the management of myofascial pelvic pain.

Genital Pain and the Spectrum of Bladder-Related Symptoms: Findings from the Prevention of Lower Urinary Tract Symptoms Research Consortium RISE FOR HEALTH Study, USA

INTRODUCTION AND HYPOTHESIS

Women with vulvovaginal or genital pain more commonly experience interstitial cystitis/bladder pain syndrome (IC/BPS) and urinary tract infections. However, the relationship between genital pain and bladder health is lacking.

METHODS

Women in the Prevention of Lower Urinary Tract Symptoms Consortium's RISE FOR HEALTH population-based study answered questions about bladder health globally, and across nine bladder health domains of holding, efficacy, social-occupation, physical activity, intimacy, travel, emotion, perception, and freedom. Bladder function was assessed across six indices including urinary frequency, sensation, continence, comfort, emptying, and dysbiosis (e.g., urinary tract infections). Participants were grouped by no pain beyond transitory events (i.e., minor headaches, toothaches, or sprains), nongenital-related pain only, and any genital pain using a validated pain diagram. Mean adjusted scores and indices were compared using general linear modelling.

RESULTS

Of 1,973 eligible women, 250 (12.7%) reported genital pain, 609 (30.9%) reported nongenital pain only, and 1,114 (56.5%) reported no pain. Women with any genital pain had lower (worse) adjusted mean scores across all bladder health scales (BHS; BHS global adjusted mean 47.5; 95% CI 40.8-54.1), compared with those with nongenital pain only (53.7; 95% CI 47.6-59.8), and no pain (59.3; 95% CI 53.3-65.4). Similarly, adjusted mean total Bladder Functional Index scores were lower for those with genital pain (63.1; 95% CI 58.4-67.9) compared with nongenital pain (72.1; 95% CI 67.7-76.5) and no pain (77.4; 95% CI 73.0-81.8).

CONCLUSIONS

Heightened awareness of the relationship between genital pain and bladder health should prompt clinicians caring for women with genital pain to assess bladder health and function.

Effects of osteopathic manipulative therapy on recurrent pelvic pain and dyspareunia in women after surgery for endometriosis: a retrospective study

BACKGROUND

Surgical removal of deep infiltrating endometriosis is frequently associated with improvement in symptoms. However, because of the complex pathogenesis of pain in endometriosis that includes central sensitization and myofascial dysfunction, symptoms can persist after surgery. The aim of the present observational study is to explore the effectiveness of osteopathic manipulative treatment (OMT) in reducing persistent pelvic pain and dyspareunia in a sample of symptomatic women surgically treated for endometriosis.

METHODS

Retrospective cohort analysis of 69 patients treated with OMT, for persistent myofascial pain, chronic pelvic pain (CPP) and dyspareunia after surgical eradication of endometriosis. Surgical, clinical and osteopathic reports were retrospectively analyzed in a chart review. Osteopathic interventions included myofascial release, balanced ligamentous/membranous tension and indirect fluidic technique.

RESULTS

During the study period 345 patients underwent surgery for symptomatic endometriosis. Among them, 97 patients (28.1%) complained of post-operative persistent CPP and dyspareunia and 69 patients underwent osteopathic treatment. OMT reports showed a significant improvement of the symptoms after the first OMT session. Particularly, lower scores of CPP (mean NRS 4±4.2 vs. 0.2±0.7, P value.

CONCLUSIONS

OMT, breaking the cycle of pain and normalizing the musculoskeletal pelvic activity, could be a successful technique to treat persistent chronic pain in women surgically treated for endometriosis.

Pain in the enthesis of levator ani muscle: A novel source of chronic pelvic pain

BACKGROUND

Managing chronic pelvic pain (CPP) remains a challenge due to its diverse range of causes. A newly identified anatomical entity known as the enthesis of the levator ani muscle (LAM) and its associated disorders might play a role. This paper describes a novel insight into CPP's origin, aiming to improve accurate diagnosis and treatment.

METHODS

Data were collected from medical records (paper or electronic) retrospectively. The study included 112 patients meeting the criteria, divided into CPP and non-CPP groups. Clinical symptoms, including location of LAM enthesis, referred pain from pain in LAM enthesis, and related lower urinary tract symptoms (LUTSs) were discussed. To identify differences in symptoms between the groups, a Chi-squared test and descriptive analyses were conducted.

RESULTS

Bimanual examination revealed tender sites in the attachment of the LAM to the pubic bone. LAM enthesis pain presumably caused referred pain in at least 10 areas, primarily in the lower abdominal quadrate (40.2%-47.3%) followed by the inguinal area (8.9%-15.1%). Multiple LUTSs were observed, including urinary frequency (72.3%), urgency (42.9%), nocturia (53.6%), residual urine sensation (64.3%), urinary incontinence (30.3%), painful bladder (34.8%), and weak urine stream (47.9%). Patients in the CPP groups experienced significant residual urine sensation (53.6%) and bearing-down sensation (42%) compared to the non-CPP group.

CONCLUSION

Pain in LAM enthesis is a novel cause of pelvic pain and LUTSs that warrants attention for the evaluation and management of CPP.

Exploring transvaginal sonographic characteristics of the levator ani muscle in women with postpartum pelvic floor myofascial pain

BACKGROUND

Pelvic floor myofascial pain is one of the pelvic floor dysfunction diseases disturbing women after delivery. There is a lack of objective standardization for the diagnosis of pelvic floor myofascial pain due to the various symptoms and the dependence on the palpating evaluation. Ultrasound imaging has the advantages of safety, simplicity, economy and high resolution, which makes it an ideal tool for the assistant diagnosis of pelvic floor myofascial pain and evaluation after treatment.

METHODS

This is a retrospective case-control study including women accepting evaluation of pelvic floor function at 6 weeks to 1 year postpartum. They were divided into pelvic floor myofascial pain group and normal control group. A BCL 10-5 biplane transducer was applied to observed their puborectalis. The length, minimum width, area, deficiency, deficiency length, deficiency width, deficiency area, rate of deficiency area, local thickening,angle between the tendinous arch of levator ani muscle and puborectalis of corresponding puborectalis in different groups were observed and measured.

RESULTS

A total of 220 postpartum women participated in the study, with 77 in the pelvic floor myofascial pain group and 143 in the normal control group. The Intraclass correlation coefficient value was over 0.750, and Kappa ranged from 0.600 to 0.800. puborectalis deficiency (adjusted odds ratio = 11.625, 95% confidence interval = 4.557-29.658) and focal thickening (adjusted odds ratio = 16.891, 95% confidence interval = 1.819-156.805) were significantly associated with higher odds of having postpartum pelvic floor myofascial pain. Grayscale or the angle between the arch tendineus levator ani and puborectalis measurements on the pain side tended to be smaller than on the non-pain side in patients with unilateral puborectalis or iliococcygeus pain (P < 0.05).

CONCLUSIONS

This study demonstrated that transvaginal ultrasound was a potentially efficient technique for evaluating postpartum pelvic floor myofascial pain due to its ability to assess various sonographic characteristics of the levator ani muscles.

Pelvic Pain of Myofascial Origin in Women: Correlation with Lower Urinary Tract Symptoms

Introduction

Women with lower urinary tract symptoms (LUTS) and high-tone pelvic floor often experience pain and have positive trigger points upon pelvic floor examination. However, the correlation of these findings has not yet been systematically examined and sufficiently understood. The aim of this cross-sectional study is to examine the correlation of pelvic myofascial pain with LUTS and pelvic floor tone.

Materials and Methods

All participants filled a standardized pelvic floor questionnaire to assess LUTS, which consists of a total of 43 questions regarding bladder, bowel, and sexual function as well as prolapse symptoms. Myofascial trigger points in different muscle groups including pubococcygeus, iliococcygeus, and obturator as well as pelvic floor muscle tone were assessed using a standardized digital examination technique.

Results

110 women were included in the study. There was a significant correlation between pain in various muscle groups and LUTS as well as high-tone pelvic floor muscle. A significant correlation could also be found between high pelvic floor muscle tone and the overall questionnaire score (p < 0.001) as well as the bladder function score (p < 0.001) and various pain scores of the different groups. Individuals with high-tone pelvic floor were more likely to have more LUTS and higher pain scores.

Conclusions

The existence of myofascial pelvic floor trigger points and high pelvic floor muscle tone seem to be reflective of pelvic floor symptoms, as assessed with a standardized pelvic floor questionnaire.

A Pilot Randomized Controlled Trial of Vaginal Cryotherapy for the Treatment of Pelvic Floor Myofascial Pain

INTRODUCTION AND HYPOTHESIS

Pelvic floor myofascial pain (PFMP) is a common but underrecognized component of chronic pelvic pain and pelvic floor disorders symptoms with limited, well-studied treatment modalities. Our objective was to determine the effect of vaginal cryotherapy on PFMP with palpation.

METHODS

Following a standardized PFMP screening examination, individuals with a pain score ≥4/10 in ≥1 of four muscle groups were invited to participate in a randomized controlled trial comparing patients undergoing vaginal cryotherapy with controls. Participants in both arms could choose to participate in a single in-office treatment; a 2-week, at-home daily treatment; or both.

RESULTS

Between March 2019 and September 2021, a total of 163 participants were enrolled and randomized: 80 to cryotherapy, and 83 to the control group. Sixty-three (28 cryotherapy; 35 controls) completed in-office treatment and 56 (32 cryotherapy; 24 controls) completed at-home therapy. In the in-office comparison, mean pain scores decreased significantly in both arms: cryotherapy (5.13 vs 4.10; p=0.02) and controls (5.60 vs 4.72; p<0.01), with a similar magnitude of reduction between arms (p=0.75). In the at-home comparison, mean pain scores decreased significantly in the cryotherapy arm (6.34 vs 4.75; p<0.01), and nonsignificantly in the control arm (5.41 vs 4.66; p=0.07), resulting in a nonsignificant difference between arms (p=0.14).

CONCLUSIONS

Pelvic floor myofascial pain with palpation improved following both a single cryotherapy session and 2 weeks of daily cryotherapy. Interestingly, pain scores also improved with room temperature therapy. Whether these findings reflect a therapeutic effect of both cold and room temperature intravaginal therapy or a placebo effect is unclear but should be explored in larger studies.

Guideline No. 445: Management of Chronic Pelvic Pain

OBJECTIVE

To provide evidence-based recommendations for the management of chronic pelvic pain in females.

TARGET POPULATION

This guideline is specific to pelvic pain in adolescent and adult females and excluded literature that looked at pelvic pain in males. It also did not address genital pain.

BENEFITS, HARMS, AND COSTS

The intent is to benefit patients with chronic pelvic pain by providing an evidence-based approach to management. Access to certain interventions such as physiotherapy and psychological treatments, and to interdisciplinary care overall, may be limited by costs and service availability.

EVIDENCE

Medline and the Cochrane Database from 1990 to 2020 were searched for articles in English on subjects related to chronic pelvic pain, including diagnosis, overlapping pain conditions, central sensitization, management, medications, surgery, physiotherapy, psychological therapies, alternative and complementary therapies, and multidisciplinary and interdisciplinary care. The committee reviewed the literature and available data and used a consensus approach to develop recommendations. Only articles in English and pertaining to female subjects were included.

VALIDATION METHODS

The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations).

INTENDED AUDIENCE

Family physicians, gynaecologists, urologists, pain specialists, physiotherapists, and mental health professionals.

TWEETABLE ABSTRACT

Management of chronic pelvic pain should consider multifactorial contributors, including underlying central sensitization/nociplastic pain, and employ an interdisciplinary biopsychosocial approach that includes pain education, physiotherapy, and psychological & medical treatments.

Characterization of Pain Associated With Pelvic Organ Prolapse: Is Surgery the Answer?

IMPORTANCE

Data on the incidence of pelvic organ prolapse (POP)-related pain, risk factors for its development, and treatment effects of surgery remain sparse.

OBJECTIVES

The aims of the study were to evaluate the incidence and characteristics of POP-related pain in patients presenting with POP and assess the outcome of pain after surgery.

STUDY DESIGN

This was a retrospective study of patients presenting for initial evaluation of POP from May 2019 to May 2020. Using a standardized questionnaire, patients were asked "Do you have pain associated with your prolapse (not pressure or fullness)?" and to indicate pain severity and location(s). Patients who underwent surgery were asked postoperatively if their POP-related pain resolved. Patient and perioperative characteristics were obtained from the medical record and used to evaluate relationships between the presence and resolution of POP-related pain.

RESULTS

Of the 795 patients who met inclusion criteria, 106 (13.3%) reported POP-related pain. The mean age of all patients was 59.9 years, 38.1% had stage 3 or greater POP, and 52.1% were sexually active. Women with POP-related pain reported a median severity of 5 of 10. The most common pain locations were the vagina (46.6%), lower abdomen (27.4%), and back (9.6%). Fifty-seven women with pain (53.8%) underwent surgery, and 40 (70.2%) reported postoperative pain resolution. Of those who did not have resolution, pain improved or remained stable in severity. No patients reported worsening pain after surgery.

CONCLUSIONS

Pain is a symptom experienced by more than 1 in 8 women presenting with POP, with 70% reporting resolution of their pain postoperatively.

Pelvic organ prolapse: Women's experiences of Accessing Care & Recommendations for improvement

Up to 50% of women will develop pelvic organ prolapse (POP) over their lifetime. Symptoms include pain, bulge, urinary, bowel and sexual symptoms affecting all aspects of a woman's life.Many women with POP symptoms present initially to primary care settings. Research has shown these interactions are often unsatisfactory, with women reporting their health care professional (HCP) trivialized their symptoms or appeared to have poor knowledge about pelvic floor dysfunction (PFD).Aim The aim of this qualitative study was to explore experiences of younger women seeking treatment for POP and their recommendations for improvements.Methods Ethics approval was obtained (LS-21-01-Carroll-Ful). Women with POP were recruited from an online support group (n = 930 members). Inclusion criteria: adult women, diagnosed with POP and aware of their POP stage. Following informed consent, a demographic questionnaire, interview questions and the Central Sensitization Inventory (CSI) were forwarded. Semi-structured zoom audio-recorded interviews were conducted. Thematic analysis was undertaken; transcripts coded, and themes identified.Results Fourteen women aged 32-41, parity 1-3, with POP Grade 1-3 participated. Many women reported HCPs as dismissive or not appreciative of the impact of their condition. Others described interactions with HCPs who they felt listened, understood the impact of their POP, gave simple explanations, a positive prognosis and outlined a realistic treatment plan.Current antenatal education, post-partum care and primary HCP screening for PFD were identified by women as deficient. Many highlighted delays in accessing specialist care for POP. Women made several recommendations for improvements to the current model of care.Conclusions Increased focus on person-centred care, particularly emotional support, information and education may improve younger women's experiences when seeking care for POP.

Chronic Pelvic Pain: Role of Imaging in the Diagnosis and Management

Chronic pelvic pain (CPP) in women is not uncommon, and it may be difficult to identify the exact cause difficult to manage. It is major health problem for women that affects the quality of their daily lives. The etiology of chronic pelvic pain may be of gynecological or non-gynecological origin and associated with several predisposing and precipitating factors. Psychological and social factors also contribute to the syndrome of CPP and must be evaluated before managing these patients. Due to multifactorial etiology, CPP needs a multidisciplinary approach for diagnosis and management. A detailed history and physical examination supported by appropriate laboratory tests and imaging are the keys to diagnosis. In this paper, the role of imaging in diagnosis and management of CPP is reviewed. Imaging findings should be correlated with detailed clinical examination findings as there are imaging findings that may be unrelated and not the cause of CPP in a particular patient, imaging findings should be correlated with the clinical circumstances.

Approach of Chronic Pelvic Pain with Top Flat Magnetic Stimulation

Materials and Methods

Vulvar Functional Status Questionnaire (VQ) was used for the evaluation of patient's chronic pelvic pain and muscle hypertone improvements. The interstitial cystitis was assessed by the Leary-Sant symptom and problem indexes (ICSI and ICPI). In this study, the scores resulting from the sum of the two indexes were evaluated as OSS (ICSI + ICPI).

Results

Women with chronic pelvic pain and muscle hypertone showed VQ mean values significantly lower than the controls (p  <  0.005) from the second treatment up to the sixth one. In 6 patients affected by interstitial cystitis, the mean score of OSS was significantly lower than the controls (p  <  0.005) from the second treatment up to 2 months follow-up after the last treatment session. No side effects were observed.

Conclusion

Based on these results, this technology may successfully manage muscle hypertonicity condition, the chronic pelvic pain, and interstitial cystitis.

Efficacy of botulinum toxin A injection in pelvic floor muscles in chronic pelvic pain patients: a study protocol for a multicentre randomised controlled trial

INTRODUCTION

Chronic pelvic pain (CPP) is a common multifactorial condition affecting 6%-27% of women aged 18-50 years worldwide. The aim of this randomised controlled trial (RCT) is to investigate the efficacy and safety of botulinum toxin A (BTA) injection compared with placebo injections in the pelvic floor muscles in women with CPP to improve pain, function and quality of life.

METHODS AND ANALYSIS

This is a study protocol for a multicentre, double-blinded placebo controlled RCT conducted in five gynaecology departments across the Netherlands. A total of 94 women over 16 years, with at least 6 months of CPP without anatomical cause and pelvic floor hypertonicity refractory to first-line pelvic floor physical therapy will be included. Participants will be randomised equally to BTA or placebo, both following physical therapy and (re-)education on the pelvic floor at 4, 8, 12 and 26 weeks after intervention. Multiple validated questionnaires focusing on pain, quality of life and sexual function will be collected at baseline and during all follow-up visits. Statistical analysis includes mixed models for repeated measurements.

ETHICS AND DISSEMINATION

Ethical approval (NL61409.091.17) was obtained from Radboud University Medical Research Ethics Committee (MREC) and Central Committee on Research involving human Subjects (CCMO). The findings will be presented through international conferences and peer-reviewed scientific journals.

TRIAL REGISTRATION NUMBER

EudraCT number (2017-001296-23), CCMO/METC number: NL61409.091.17.

Importance of internal vaginal pelvic floor muscle exams for women with external lumbar/hip/pelvic girdle pain

INTRODUCTION AND HYPOTHESIS

The relationship between external lumbar, hip, and/or pelvic girdle pain and internal vaginal pelvic floor myofascial pain is not well described. We assessed this relationship in a cohort of adult women.

METHODS

The cohort included women ≥ 18 years old who received care for external lumbar, hip, and/or pelvic girdle pain (reported or elicited on physical examination) who then underwent internal vaginal myofascial levator ani pain assessments, in a tertiary care Female Pelvic Medicine and Reconstructive Surgery pelvic pain clinic over a 2-year period (2013 and 2014).

RESULTS

The cohort of 177 women had an average age of 44.9±16.0 years, an average body mass index of 27.2±7.0 kg/m2, and the majority (79.2%) were white. Most patients presented with a chief complaint of pelvic (51.4%), vulvovaginal (18.6%), and/or lumbar (15.3%) pain. Women who reported symptoms of lumbar, hip, or pelvic girdle pain were more likely to have pain on vaginal pelvic floor muscle examination than women without this history (OR, 7.24; 95% CI, 1.95-26.93, p=0.003). The majority (85.9%) of women had bilateral internal vaginal pelvic floor myofascial pain on examination.

CONCLUSIONS

Although participants did not describe "vaginal pelvic floor myofascial pain," the high detection rate for internal vaginal pelvic floor myofascial pain on clinical examination highlights an opportunity to improve treatment planning. These findings suggest that the vaginal pelvic floor muscle examination should be part of the assessment of all women with lumbar, hip, and/or pelvic girdle pain. The relationship between this finding and clinical outcomes following directed treatment warrants additional study.

A pilot trial of movement-based pelvic floor physical therapy to address pelvic floor myofascial pain and lower urinary tract symptoms

INTRODUCTION AND HYPOTHESIS

Pelvic floor myofascial pain (PFMP) is associated with lower urinary tract symptoms (LUTS). The objective of this study was to test movement-based pelvic floor physical therapy (PT) for patients with PFMP and LUTS. We hypothesized that movement-based PT designed to target PFMP would result in significant improvement in both PFMP and concomitant LUTS.

METHODS

This pilot trial enrolled patients with moderate-to-severe PFMP on palpation who were referred to movement-based PT to diagnose and treat pelvic floor dysfunction in the context of body alignment and movement patterns. The primary outcome was change in Urogenital Distress Inventory (UDI) scores after PT. Factors associated with PT attendance were also measured. We aimed to enroll 55 participants to achieve 80% power to detect a difference in 11 points on the UDI scores with an alpha-level of 0.05, accounting for a 10% loss to follow-up. The sample size was increased to 65 owing to a higher-than-expected loss-to-follow-up rate.

RESULTS

Sixty-five patients were enrolled and 62 analyzed. Thirty-eight (61.3%) attended PT, and 30 (48.4%) completed a follow-up PT Attendance (PTA) survey. Overall, UDI score and irritative, obstructive, and stress subscales (p<0.0001) improved in participants who attended PT as well as mean myofascial examination scores at each site.

CONCLUSIONS

Participants who attended movement-based PT demonstrated an improvement in LUTS. Future studies should extend our findings by: first, confirming whether the myofascial pain-directed elements of PT improved LUTS; second, investigating whether movement-based PT improves prolapse symptoms; and third, including a non-PT control arm to rule out the possible influence of a placebo effect and behavioral modifications on LUTS and PFMP.

Women with Chronic Pelvic Pain Demonstrate Increased Lumbopelvic Muscle Stiffness Compared to Asymptomatic Controls

Background: Although lumbopelvic muscle stiffness is commonly clinically assessed in women with chronic pelvic pain (CPP), it has not been objectively quantified in this population, and its association with other pain-related impairments has not yet been established. Objective: To compare superficial lumbopelvic muscle stiffness in women with and without CPP. In addition, pressure pain threshold (PPT) was compared between groups and the associations between muscle stiffness and PPT were assessed in women with CPP. Study Design: Case-control. Methods: Muscle stiffness and PPT of 11 lumbopelvic muscles were assessed in 149 women with CPP and 48 asymptomatic women. Subjective outcome measures, including pelvic floor function, health history, and psychosocial outcomes, were collected before muscle stiffness and PPT measurements. Analysis of covariance was used to compare muscle stiffness differences between groups, and independent t-tests were used to compare PPT between groups. Associations between measurements of PPT and muscle stiffness were calculated using correlation analysis. Results: Five of the 11 muscles measured were significantly stiffer in women with CPP than those without CPP (p < 0.05). PPT was significantly decreased in all muscles measured in women with CPP; however, there was not a significant association between muscle stiffness and PPT in women with CPP. Conclusion: The study identified the abdominal lumbopelvic muscles that have increased stiffness in women with CPP compared to asymptomatic women. In addition, muscle stiffness and PPT are two distinct impairments within this population. The results suggest that women with CPP have peripheral muscle impairments, which may be addressed without intravaginal or intrarectal intervention. Clinical Trial Registration: NCT04851730.

Pelvic Pain and Pelvic Floor Muscle Dysfunction in Women Seeking Treatment for Prolapse

IMPORTANCE

Pelvic floor muscle dysfunction (PFMD) can cause pelvic pain, but its associations with pelvic organ prolapse (POP) and POP treatment outcomes are poorly understood.

OBJECTIVES

The objectives of this study were to determine (1) if pelvic pain is associated with PFMD in women seeking POP treatment and (2) if baseline PFMD in women seeking management of POP is associated with improvement in pelvic pain at 12 months.

STUDY DESIGN

This was an ambispective cohort study of women enrolled at one site of the Pelvic Floor Disorders Registry. Pelvic floor muscle dysfunction was identified if tenderness was reported on a standardized pelvic floor muscle examination at baseline. Outcomes included a pelvic pain questionnaire (score 0-70, assessed pain in the past 24 hours in 7 pelvic locations) and the Global Health-10 overall average pain rating (0-10).

RESULTS

One hundred forty-four women planning surgery (118) or pessary (26) were included. Twenty (13.9%) had baseline PFMD. Women with PFMD versus no PFMD had greater baseline Pelvic Pain scores (median [IQR], 9.7 [4-23] vs 2.5 [0-7], P < 0.001) and overall average pain (4 [3-6] vs 1 [0-3], P < 0.001). In 107 women with 12-month treatment outcomes, those with PFMD at baseline had greater improvement in pelvic pain compared with those without PFMD (change score -6.5 [-15.2 to 0] vs 0 [-3 to 0] respectively, P = 0.03). Overall pain improved after treatment in the no PFMD group but not in the PFMD group.

CONCLUSIONS

Patients with baseline PFMD vs none undergoing treatment for prolapse had higher baseline pelvic pain and greater improvement in pelvic pain at 12 months.

Comprehensive pelvic muscle assessment: Developing and testing a dual e-Learning and simulation-based training program

OBJECTIVE

The Prevention of Lower Urinary Tract Symptoms (PLUS) research consortium launched the RISE FOR HEALTH (RISE) national study of women's bladder health which includes annual surveys and an in-person visit. For the in-person exam, a standardized, replicable approach to conducting a pelvic muscle (PM) assessment was necessary. The process used to develop the training, the products, and group testing results from the education and training are described.

METHODS

A comprehensive pelvic muscle assessment (CPMA) program was informed by literature view and expert opinion. Training materials were prepared for use on an electronicLearning (e-Learning) platform. An in-person hands-on simulation and certification session was then designed. It included a performance checklist assessment for use by Clinical Trainers, who in collaboration with a gynecology teaching assistant, provided an audit and feedback process to determine Trainee competency.

RESULTS

Five discrete components for CPMA training were developed as e-Learning modules. These were: (1) overview of all the clinical measures and PM anatomy and examination assessments, (2) visual assessment for pronounced pelvic organ prolapse, (3) palpatory assessment of the pubovisceral muscle to estimate muscle integrity, (4) digital vaginal assessment to estimate strength, duration, symmetry during PM contraction, and (5) pressure palpation of both myofascial structures and PMs to assess for self-report of pain. Seventeen Trainees completed the full CPMA training, all successfully meeting the a priori certification required pass rate of 85% on checklist assessment.

CONCLUSIONS

The RISE CPMA training program was successfully conducted to assure standardization of the PM assessment across the PLUS multicenter research sites. This approach can be used by researchers and healthcare professionals who desire a standardized approach to assess competency when performing this CPMA in the clinical or research setting.

Pelvic pain is a common prolapse symptom and improvement after ventral mesh rectopexy is more frequent than deterioration or de novo pain

AIM

The aim of this work was to assess the relationship between pelvic pain and rectal prolapse both before prolapse surgery and in the long term after ventral mesh rectopexy (VMR).

METHOD

Patients undergoing VMR between 2004 and 2017 were contacted. Outcomes including the severity of pelvic pain were recorded using a numeric rating scale.

RESULTS

Four hundred and seventy eight of the 749 patients (64%) were successfully contacted. Of these, 39% reported pre-existing pelvic pain prior to VMR (group A) and 61% were pain free (group B). The median follow-up time was 8.0 years (interquartile range 5.0-10.0 years). Symptoms of obstructed defaecation were significantly more common (p = 0.002) in group A (91/187, 49%) than in group B (101/291, 35%). In contrast, faecal incontinence was more common (p = 0.007) in group B (75/291, 26%) than in group A (29/187, 15%). In group A, 76% showed improvement in pelvic pain after VMR: 61% were pain free and 39% had partial improvement in their pre-existing pelvic pain. Patients with persistent pelvic pain were younger (p = 0.01) and more likely to have revisional surgery after VMR (p = 0.0003), but there was no relation to the indication for surgery (p = 0.59). In group B, 15% reported de novo pelvic pain after VMR, and this was more common in women under 50 years old (p = 0.001), when obstructed defaecation was the indication (p = 0.03), in mesh erosion (p = <0.05) and when associated with revisional surgery (p = 0.005).

CONCLUSION

Pelvic pain is common (39%) in patients undergoing prolapse surgery, and VMR improves this pain in most patients (76%). However, a significant number of patients fail to improve (12%), experience worsening of pain (12%) or develop de novo pelvic pain (15%).

The prediction and treatment of postpartum myofascial pelvic pain

BACKGROUND

The clinical manifestations of myofascial pelvic pain (MFPP) are mainly acute or chronic muscle pain at one or more trigger points in the pelvic cavity or pelvic floor.

OBJECTIVE

This study aims to explore the predictive value of pelvic floor myoelectric parameters with respect to MFPP and the effect of its clinical treatment.

METHODS

Two hundred and one women followed up in the Wenzhou People's Hospital 6-12 weeks postpartum between July 2020 and July 2021. They were divided into an MFPP group (n= 90) and a non-MFPP group (n= 102), but 9 MFPP patients without a pelvic floor electromyography evaluation were not included. The general demographic data and pelvic floor electromyography evaluation parameters of the two groups were compared; the related factors of postpartum women suffering from MFPP were analyzed, and a nomogram model of the postpartum risk of suffering from MFPP was established. The 99 patients with postpartum MFPP were divided into a treatment group (n= 10) and a control group (n= 89). The difference in visual analog scale scores between the two groups initially and after three months of treatment was compared to evaluate the effective remission rate of postpartum MFPP after treatment.

RESULTS

A significant difference was observed in the relaxation time at the rapid contraction stage (z= 4.369, p< 0.05) and the tension contraction stage (z= 135.645, p< 0.01) between the MFPP group and the non-MFPP group. The nomogram model for predicting postpartum MFPP was established with nine variables as potential predictors. The calibration chart and C index of 0.68 (95% CI: 0.65-0.71) proved that the model had a certain degree of discrimination. The clinical decision-making curve showed that the model could increase the net benefit rate of patients. The pain relief rate in the treatment group was significantly higher than that in the control group (p< 0.01).

CONCLUSION

There is a significant correlation between postpartum MFPP and relaxation time at rapid contraction stage and tension contraction stage. The risk prediction nomogram model of postpartum MFPP established with nine potential predictors has a certain prediction capability, and clinical treatment can effectively relieve MFPP in postpartum patients.

Overactive Bladder Patients With and Without Urgency Incontinence: A Spectrum of One Condition or Different Phenotypes?

IMPORTANCE

The importance of this study is to explore potential differences in pathophysiologies of OAB-wet and OAB-dry.

OBJECTIVES

The aim of this study was to define fundamental and unique presenting features of patients exhibiting storage lower urinary tract symptoms (LUTS) with urgency incontinence (OAB-wet) and patients without urgency incontinence (OAB-dry).

STUDY DESIGN

This was a secondary analysis of cross-sectional data from the National Institutes of Health/National Institute of Diabetes and Digestive and Kidney Diseases-sponsored Symptoms of Lower Urinary Tract Dysfunction Research Network. Demographic, physical examination, and questionnaire responses were analyzed for women seeking care for LUTS at 6 U.S. centers. Differences between OAB-wet and OAB-dry patients were compared using the Fisher exact test and Mann-Whitney U test. Differences in questionnaire data were assessed using a Benjamini-Hochberg false discovery rate correction.

RESULTS

Fifty-six, 84, and 67 women were included in the OAB-dry, wet, and control cohorts, respectively. There was no difference in demographic and physical examination characteristics of the 2 groups. OAB-wet patients reported more urgency incontinence symptoms (LUTS 16a, P < 0.001). OAB-dry reported more bladder pain, feeling of incomplete bladder emptying (LUTS 4, P < 0.001), and a need to strain to urinate (AUA-SI 7, P = 0.003). Sensation of incomplete emptying and straining with urination did not correlate with elevated postvoid residual volumes. Although degrees of symptomatic bother were similar, bother in OAB-dry patients was most closely related to pelvic floor tenderness severity, whereas bother in OAB-wet patients was most related to urgency severity.

CONCLUSIONS

Women with OAB-dry have distinct presenting features of straining with urination, bladder pain, and a feeling of incomplete emptying. These suggest a unique pathophysiology driving OAB-dry symptoms, which we hypothesize is pelvic floor myofascial dysfunction.

Pelvic Floor Mobility measured by Transperineal Ultrasound Imaging in Women with and without Urgency and Frequency Predominant Lower Urinary Tract Symptoms

BACKGROUND

Women with urgency/frequency predominant lower urinary tract symptoms (UF-LUTS) may have elevated pelvic floor muscle (PFM) position at rest and limited mobility with PFM contraction and bearing down, but this has not been quantified.

OBJECTIVES

To compare PFM position and mobility using transperineal ultrasound (TPUS) at rest, maximal PFM contraction (perineal elevation), and bearing down (perineal descent) in women with and without UF-LUTS. We hypothesized that women with UF-LUTS would demonstrate elevated resting position and decreased excursion of pelvic landmarks during contraction and bearing down as compared to women without UF-LUTS.

STUDY DESIGN

Case-control study.

METHODS

Women with UF-LUTS were matched 1:1 on age, body mass index and vaginal parity to women without UF-LUTS. TPUS videos were obtained during 3 conditions: rest, PFM contraction, and bearing down. Levator plate angle (LPA) and puborectalis length (PR length), were measured for each condition. Paired t-tests or Wilcoxon signed rank tests compared LPA and PR length between cases and controls.

RESULTS

21 case-control pairs (42 women): Women with UF-LUTS demonstrated greater LPA at rest (66.8 ± 13.2 degrees vs 54.9 ± 9.8 degrees; P=0.006), and less PR lengthening from rest to bearing down (0.2 ± 3.1 mm vs 2.1 ± 2.9 mm; P=.03).

CONCLUSION

Women with UF-LUTS demonstrated more elevated (cranioventral) position of the PFM at rest and less PR muscle lengthening with bearing down. These findings highlight the importance of a comprehensive PFM examination and possible treatment for women with UF-LUTS to include PFM position and mobility.

The efficacy of botulinum toxin a injections in pelvic floor muscles in chronic pelvic pain patients: a systematic review and meta-analysis

Introduction and hypothesis

Chronic pelvic pain (CPP) is a common multifactorial condition affecting 6 to 27% of women aged 18–50 years worldwide. This study was conducted to review and meta-analyse the current literature on the reduction of chronic pelvic pain after botulinum toxin A (BTA) injection.

Method

In July 2021 we performed a systematic search in PubMed and EMBASE to assess the benefits of BTA injection in pelvic floor muscles in women with chronic pelvic pain. Primary outcome was reduction in visual analogue scale (VAS) after treatment. Secondary outcomes evaluated were: reduction of dyspareunia, pelvic floor resting pressure and quality of life. Identified reports were assessed on quality of reporting and risk of bias. Standardized mean difference (SMD) was used to combine and analyse outcomes of the included studies.

Results

Eight studies with 289 participants were considered eligible to be included in this systematic review and meta-analysis. After recalculating SMD into VAS scores (0–100), long-term follow-up (24–26 weeks) showed a significant 15-point improvement in VAS scores (95% CI: 8.8–21.5) for non-menstrual pelvic pain and a 13-point improvement (95% CI: 2.1–24.0) for dyspareunia. BTA injection had a significant effect on pelvic floor resting pressure and quality of life.

Conclusion

There is limited scientific evidence on the effectiveness of BTA injections in pelvic floor muscles in women with chronic pelvic pain. The available studies show that BTA injections significantly reduce pain levels and improve quality of life at 6 months follow-up.

Vaginal stretching therapy and class IIIB vaginal laser treatment for pelvic floor myofascial pain: a randomized clinical trial

PURPOSE

Several treatment options are proposed for the management of pelvic floor myofascial pain (PFMP). Manual therapy, such as vaginal stretching (VS), is one of these options. Photobiomodulation therapy (PBMT) with a laser device is a treatment option for PFMP that has been tested on other muscles. The aim of this study was to evaluate the effect of VS combined or not with PBMT for PFMP treatment.

METHODS

One hundred three women with PFMP were enrolled in a double-blind randomized trial and assigned to VS+PBMT (10 treatments over 2 weeks with 100 mw delivering 12 joules to surface intravaginally, using near-infrared light 808 nm) and VS+shamPBMT treatment groups. Pain severity was assessed by Visual Analog Scale (VAS). Pelvic floor muscle function was assessed by Oxford Scale and surface electromyography. Urinary symptoms were evaluated by ICIQ-OAB and ICIQ-SF questionnaires, and intestinal constipation was assessed by ROMA criteria.

RESULTS

There was a significant improvement in pain intensity (VAS) after treatment in both groups, with no difference between groups (p = 0.46). More than 50% of the women complained of severe pain before treatment, and after treatments, it was reported by less than 20% of women (p < 0.001), with no difference between groups (p = 0.08). Urinary symptoms improved in both groups (p < 0.001) with no difference between groups (p = 0.37). Intestinal constipation improved in the VS+PBMT group only (p = 0.01).

CONCLUSION

VS and VS with near-infrared vaginal laser therapy were equally effective at decreasing myofascial pelvic pain and reducing urinary symptoms TRIAL REGISTRATION: REBEC (Registro Brasileiro de Ensaios Clínicos; Brazilian Registry of Clinical Trials) under no.RBR-2TDCQ4 (November 11, 2018).

Effect of Vaginal Stretching and Photobiomodulation Therapy on Sexual Function in Women with Pelvic Floor Myofascial Pain - A Randomized Clinical Trial

BACKGROUND

Spasm or increased tonus of the pelvic floor muscles (PFM) can cause myofascial pain (MP), which may result in painful intercourse and sexual dysfunction.

AIM

The effect of vaginal stretching (VS) with photobiomodulation therapy (PBMT) is compared to VS with sham PBMT in overall sexual function, rate and severity of painful intercourse at baseline and after treatment in women with pelvic floor MP.

METHODS

A double-blind randomized clinical trial of 103 women with MP: 1 group received 10 sessions of VS with PBMT (4 Joules of near-infrared light-808 nm at 3 points), and the other group received VS with sham PBMT.

OUTCOMES

Impact of treatment was measured by the number of women experiencing painful intercourse, Pain severity was measured by Visual Analog Scale and sexual function was assessed by the FSFI questionnaire. Variables were assessed at baseline and after ten sessions in the intervention groups.

RESULTS

After treatment, the number of women experiencing painful intercourse was significantly lower in both the VS with PBMT group (90.2-55%, P = .001), and VS with sham PBMT group (86.6-46.2%, P < .001). There was a significant reduction in pain measure by Visual Analog Scale (P < .001, [VS with PBMT group: P = .002; VS with sham PBMT group: P < .001]). There was a significant decrease in the number of participants with sexual dysfunction (FSFI score ≤26.55) after the treatment in the VS with PBMT group (92.2-74.5%, P = .003) and in the VS with sham PBMT group (90.4-76.9%, P = .035). Both groups showed improvement in the FSFI pain domain after treatment (P < .001, [VS with PBMT group: P = .038; VS with sham PBMT group: P = .005]). Only the VS with sham PBMT group had a significant increase in FSFI desire and total score (P < .001) after treatment.

CLINICAL IMPLICATIONS

We found that VS associated or not with PBMT may be effective in reducing complaints of painful intercourse, alleviating pain severity, and reducing the number of women with pelvic floor MP suffering from sexual dysfunction.

STRENGTHS & LIMITATIONS

Strengths of this study are the randomized design and use of validated questionnaires. Limitation of the study is the lack of a long follow-up period and the lack of a usual care comparison group hampers generalizability of the results.

CONCLUSION

VS only and VS with PBMT have short-term efficacy in reducing painful intercourse and reducing a number of women with sexual dysfunction.

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.

Factors Associated With Myofascial Dysfunction of the Pelvic Floor Muscles in Women With Urinary Incontinence: A Cross-Sectional Study

OBJECTIVES

This study aimed to evaluate the prevalence and associated factors of pelvic floor myofascial dysfunction (PFMD) in women with urinary incontinence (UI).

METHODS

A cross-sectional study was performed. Pelvic floor myofascial dysfunction was defined by pain of any intensity during palpation of the pelvic floor muscles and strength assessed by the modified Oxford scale, and was classified in grade I (mild pain), grade II (moderate), and grade III (severe). Univariate and multivariate analyses were calculated (5% significance level) to seek for the associated factors of PFMD.

RESULTS

A total of 234 women with UI were included, 121 women in the PFMD group and 113 in the control group. The mean ages were 52.1 ± 10.2 and 53 ± 8.1 years, respectively. Pelvic floor myofascial dysfunction was more frequent among non-White women, and women with PFMD presented more dyspareunia and recurrent urinary tract infection. There was a higher frequency of mixed UI (MUI; 89.2%) in the PFMD group and stress UI (31.9%) in the control group. The prevalence of PFMD was 51.7%, with 10.6% of patients categorized into grade I, 18.8% in grade II, and 22.2% in grade III. In women with PFMD, there is an inverse relation between pain and muscle strength, with the highest strength values (3, 4, and 5) being in grade I (P = 0.028). The multivariate analysis has shown that women with MUI had a risk 4.9 times greater (adjusted odds ratio, 4.93 [2.34-10.42]; P < 0.001) of having PFMD, and non-White women had a 2.1-fold increased risk (adjusted odds ratio, 2.07 [1.10-3.91]; P = 0.024) of presenting with PFMD.

CONCLUSIONS

A high prevalence of PFMD was found among women with UI. Mixed UI and non-White race were the associated factors of PFMD.

Is There a Difference in Whole Body Standing Posture in Women With Urinary Incontinence Based on the Presence of Myofascial Dysfunction in the Pelvic Floor Muscles?

OBJECTIVE

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).

METHODS

A cross-sectional study was performed with 234 women who had UI and were at least 18 years old at the urogynecology outpatient clinic of a tertiary academic hospital. The International Consultation on Incontinence Questionnaire-Short Form and the International Consultation on Incontinence Questionnaire-Overactive Bladder were used to collect urinary data. Standing postural assessment was performed using photogrammetry in anterior, posterior, and right and left lateral views and was analyzed with Postural Assessment Software. MD was defined as pain of any intensity during palpation of the PFM, and the strength of these muscles was evaluated using the Modified Oxford Scale.

RESULTS

The prevalence of MD in women with UI was 51.7% (121/234). Women with MD had significantly smaller angles in the horizontal alignment of the pelvis in the right-side view (mean [SD] = -11.9 [6.9] degrees and -9.6 [7.1] degrees), left-side view (-13.6 [6] degrees and -11.5 [6.6] degrees), and vertical alignment of the body in the left-side view (3 [1.5] degrees and 3.4 [1.5] degrees), showing anterior pelvic tilt and posterior displacement of the body.

CONCLUSION

Women with UI and MD had greater anterior pelvic tilt and posterior displacement of the body than women without dysfunction.

IMPACT

This study informs physical therapists and other health care professionals about the prevalence of MD in the pelvic floor muscles of women with UI and highlights the need to rule out MD, because it appears to be a concomitant impairment in women who self-report UI. During a postural screen, health care professionals should look for anterior pelvic tilt relative to horizon when evaluating posture in women with UI and MD. The findings of postural changes in women with MD and UI may influence the PFM assessment.

LAY SUMMARY

Women with involuntary urinary loss, pain, and stiffness in the pelvic area may show changes in posture associated with this condition.

Painful Bladder Syndrome/Interstitial Cystitis and High Tone Pelvic Floor Dysfunction

This article provides an overview of 2 conditions that defy straightforward characterization and treatment: interstitial cystitis/painful bladder syndrome often coexists with high tone pelvic floor dysfunction. These conditions are common in gynecologic patients who present with chronic pelvic pain and are often misdiagnosed due to their syndromic nature and amorphous definitions. Clinicians should maintain a high level of suspicion for these processes in patients with chronic pelvic pain or recurrent urinary tract infection symptoms. Optimal treatment uses a multimodal approach to alleviate symptoms.

Depression Partially Mediates the Association of Adverse Childhood Experiences with Pain Intensity in Patients with Chronic Pelvic Pain Syndrome: Results from a Cross-Sectional Patient Survey

OBJECTIVE

Adverse childhood experiences (ACEs), such as emotional and physical maltreatment, are linked to chronic pelvic pain syndrome (CPPS) in adults. Psychological factors are important in understanding CPPS. We aimed to determine the nature and frequency of ACEs in male and female patients with CPPS and to investigate whether somatic symptoms and psychological comorbidities mediate the relationship of ACE severity with pain intensity.

DESIGN

Cross-sectional study.

SETTING

Interdisciplinary outpatient clinic for CPPS in Hamburg, Germany.

SUBJECTS

Individuals with CPPS (n = 234) who were 18 to 84 years of age.

METHODS

Using a self-administered questionnaire, we assessed the history of ACEs (ACE Scale), pain intensity (McGill Pain Questionnaire), somatic symptoms (Patient Health Questionnaire-15]), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder Scale). Parallel mediation analysis was conducted to examine whether the association of ACE severity with pain intensity is mediated by somatic symptoms, depression, and anxiety.

RESULTS

Emotional abuse and neglect were reported more than twice as often as physical abuse and neglect (37.2% vs 17.1%). Depression partially mediated the association of ACE severity with pain intensity in the whole study population. In sex-stratified analyses, different patterns of associations were observed, but somatic symptoms predicted pain intensity in both sexes.

CONCLUSIONS

Emotional maltreatment was highly prevalent, supporting an increased consideration of psychological factors in CPPS and indicating the need to screen for ACEs in patients with CPPS. Findings further suggest that depression and somatic symptoms may be important targets for therapeutic interventions in patients with CPPS who have a history of childhood adversity.

Evaluation of a novel deep tissue transvaginal near-infrared laser and applicator in an ovine model

Photobiomodulation therapy (PBMT) is an effective means of treating muscle spasm and pain. A novel near-infrared laser system has been commercialized for the treatment of myofascial pelvic pain in women (SoLá Therapy, UroShape, LLC). This study was undertaken to determine if this device is capable of delivering therapeutic levels of irradiance to the pelvic muscles and to identify the surface irradiance required to achieve this goal. This novel class IV near-infrared laser and transvaginal applicator were used to deliver near-infrared light energy through the vaginal mucosa of an adult Suffolk/Dorset Ewe. Irradiance was measured on the surface of the levator ani muscle, inside the levator ani muscle, and inside the bladder. Measurements were taken at powers of 5 W and 0.5 W. 3.0% of vaginal surface irradiance was measured inside of the levator ani muscle. 4.4% of vaginal surface irradiance was measured inside the bladder. At 5 W, the novel laser system provided a surface irradiance of 738 mW/cm². At 0.5 W, the system provided a surface irradiance of 74 mW/cm². A novel class IV near-infrared laser and transvaginal applicator delivered therapeutic irradiance to the levator ani muscle and bladder of an anesthetized ewe at a power setting of 5 W. A power setting of 0.5 W failed to deliver therapeutic energy into either the levator ani muscle or bladder. Clinical applications targeting deeper tissues such as the pelvic muscles and or bladder should consider power settings that exceed 0.5 W and or irradiance of ≥ 75 mW/cm².

Restricted Convalescence Following Urogynecologic Procedures: 1-Year Outcomes From a Randomized Controlled Study

OBJECTIVE

To assess the relationship between postoperative activity recommendations and satisfaction and anatomic and functional outcomes 1 year after surgery for symptomatic prolapse.

METHODS

This is a planned secondary analysis reporting 1-year functional and anatomic outcomes of a multicenter, randomized, double-masked clinical trial "ReCOUP." In the original trial, women undergoing surgery for prolapse were randomized to liberal (no limitations on physical activity) or restricted (heavy lifting and high-impact activity prohibited) postoperative activity recommendations for 3 months after surgery. At 1 year, our primary outcome was satisfaction, assessed using a 5-point Likert scale answer to the question, "How satisfied are you with the result of your prolapse surgery?" Anatomic surgical failure was met if women had prolapse beyond the hymen, apical descent greater than one third the vaginal length, OR retreatment for prolapse.

RESULTS

Of the 95 women (n = 45 liberal, n = 50 restricted) who were randomized and completed primary 3-month outcomes, 83 (87%) completed a functional assessment, and 77 (81%) completed both functional and anatomic assessment at 1 year. Satisfaction with surgery remained high (91.5%) with no differences between groups (86.8% vs 95.6% P = 0.155) as did anatomic and functional outcomes. There were 7.8% women who met criteria for anatomic surgical failure with no difference between the restricted (7.0%) and liberal group (8.8%). Three women (2 in the restricted group, 1 in the liberal group) with recurrent prolapse and underwent surgery.

CONCLUSIONS

There were no significant differences in anatomic and functional outcomes at 12 months after surgery in women who resume postoperative activity liberally and those who restrict postoperative activity.

Effectiveness of Botulinum Toxin for Treatment of Symptomatic Pelvic Floor Myofascial Pain in Women: A Systematic Review and Meta-analysis

OBJECTIVES

The aims of the study were to systematically review the literature and to synthesize the evidence for the effectiveness of botulinum toxin injection to the pelvic floor muscles for treating pelvic floor myofascial pain in female patients.

METHODS

This systematic literature search was performed in February 2018 and updated in September 2019. Articles were screened based on predefined criteria: (1) adult population, (2) female patients, (3) treatment of pelvic pain by transvaginal botulinum toxin injection into the pelvic floor, (4) published in English or English translation available, (5) study design including randomized controlled trials, cohort studies, and case series with more than 10 participants, and (6) quantitative report of pain scores. Nine studies were included in the primary analysis, and an unpublished study was included in a sensitivity analysis. A random effects model with robust variance estimation was used to estimate the pooled mean difference in patient-reported pain scores after botulinum toxin injection.

RESULTS

A statistically significant reduction in patient-reported pain scores was noted at 6 weeks after botulinum toxin injection (mean difference, 20.3; 95% confidence interval, 11.7-28.9) and continued past 12 weeks (mean difference, 19.4; 95% confidence interval, 14.6-24.2). Significant improvement was noted in secondary outcomes including dyspareunia, dyschezia, and quality of life.

CONCLUSIONS

This systematic review and meta-analysis support the conduct of future, large-scale randomized controlled trials to determine the efficacy and optimize administration of botulinum toxin injections for treatment of pelvic floor myofascial pain and associated symptoms in women.

Pain after permanent versus delayed absorbable monofilament suture for vaginal graft attachment during minimally invasive total hysterectomy and sacrocolpopexy

OBJECTIVES

The objective was to evaluate pain and dyspareunia in women undergoing minimally invasive total hysterectomy and sacrocolpopexy (TLH + SCP) with a light-weight polypropylene mesh 1 year after surgery.

METHODS

This is a planned secondary analysis of a randomized trial comparing permanent (Gore-Tex) versus absorbable suture (PDS) for vaginal attachment of a y-mesh (Upsylon™) during TLH + SCP in women with stage ≥II prolapse. Patient data were collected at baseline and 1 year after surgery. Our primary outcome was patient-reported pain or dyspareunia at 1 year.

RESULTS

Two hundred subjects (Gore-Tex n = 99, PDS n = 101) were randomized and underwent surgery. Overall, the mean age ± SD was 60 ± 10 years, and BMI was 27 ± 5 kg/m². The majority were white (89%), menopausal (77%), and had stage III/IV (63%) prolapse. 93% completed a 1-year follow-up and are included in this analysis (Gor-Tex n = 95, PDS n = 90). The overall rate of participants who reported pain at 1 year was 20%. Of those who did not report any pain at baseline, 23% reported de novo dyspareunia, 4% reported de novo pain, and 3% reported both at 1 year. Of participants who reported pain or dyspareunia at baseline prior to surgery, 66% reported resolution of their symptoms at 1 year. There were no differences in most characteristics, including mesh/suture exposure (7% vs 5%, p = 0.56) between patients who did and did not report any pain at 1 year. On multiple logistic regression controlling for age, baseline dyspareunia, and baseline pain, baseline dyspareunia was associated with a nearly 4-fold increased odds of reporting any pain at 1 year (OR 3.8, 95%CI 1.7-8.9).

CONCLUSIONS

The majority of women report resolution of pain 1 year following TLH + SCP with a low rate of de novo pain.

The Case for Comorbid Myofascial Pain-A Qualitative Review

Myofascial pain syndrome is widely considered to be among the most prevalent pain conditions, both in the community and in specialized pain clinics. While myofascial pain often arises in otherwise healthy individuals, evidence is mounting that its prevalence may be even higher in individuals with various comorbidities. Comorbid myofascial pain has been observed in a wide variety of medical conditions, including malignant tumors, osteoarthritis, neurological conditions, and mental health conditions. Here, we review the evidence of comorbid myofascial pain and discuss the diagnostic and therapeutic implications of its recognition.

Clinical presentation and characteristics of pelvic floor myofascial pain in patients presenting with constipation

BACKGROUND

Patients with pelvic floor myofascial pain (PFMP) have puborectalis tenderness on digital rectal examination (DRE). Little is known about its significance to anorectal function in patients presenting with constipation.

AIM

To characterize demographics, clinical characteristics, findings on anorectal manometry (ARM), diagnosis of rectal evacuation disorder (RED), colonic transit [normal (NTC) or slow (STC)], and imaging in constipated patients with PFMP and compare these features to constipation without PFMP.

METHODS

We performed an electronic medical records review of patients with constipation evaluated by a single gastroenterologist between January 2008 and February 2019. Patients with PFMP were compared to controls with constipation but without PFMP (1:2 ratio).

KEY RESULTS

A total of 98 PFMP cases and 196 controls were identified. Constipated patients with PFMP were more likely to have RED [OR 7.59 (3.82-15.09), P < .01]; controls were more likely to have either NTC [OR 4.25 (1.45-12.42), P < .01] or STC [OR 3.57 (1.45-8.78), P < .01]. RED in patients with PFMP is supported by comparison to controls: On DRE, they had increased resting tone [OR 2.25 (1.33-3.83), P < .01] and paradoxical contraction of the puborectalis upon simulated evacuation [OR 3.41 (1.94-6.00), P < .01]; on ARM, they had higher maximum resting pressure (102.9 mmHg vs 90.7 mmHg, P < .01) and lower rectoanal pressure gradient (-39.4 mmHg vs -24.7 mmHg, P < .01).

CONCLUSIONS/INFERENCES

In constipated patients, PFMP is highly associated with RED. Its presence provides a valuable clue regarding the etiology of a patient's constipation; it should be assessed in all patients with constipation and should also be an additional target for management.
