The use of perineal ultrasound to quantify levator activity and teach pelvic floor muscle exercises

Novel Method of Measuring Pelvic Floor Muscle Motion May Improve Accessibility of Pelvic Floor Muscle Coordination Training

INTRODUCTION AND HYPOTHESIS

Pelvic floor muscle ultrasound is an important clinical tool for improving motor coordination and even strength. Although the gold standard approach involves transperineal probe placement, this is not always feasible with sensitive populations, requires privacy owing to probe placement, and additional sonography training. This article introduces a novel transabdominal method for measuring pelvic floor muscle motion that incorporates a reference point within the bladder. The hypothesis is that the novel measurement will correlate positively with transperineal measurements.

METHODS

A total of 55 women (15 nulliparous, 40 parous; 20 continent, 35 incontinent) performed pelvic floor muscle contraction and strain. Transabdominal ultrasound measured bladder diagonal length (BDL) and transperineal ultrasound measured bladder neck height (BNH), levator plate length (LPL), and levator plate angle (LPA). Spearman's test measured the correlation between the measurement outcomes and an independent t test compared outcomes based on parity and stress urinary incontinence symptom status.

RESULTS

Spearman's correlation showed moderate positive correlations between the pelvic floor measurements for both tasks, which reduced slightly when grouping by parity and symptom status. Group differences were significant for BDL during the muscle contraction, factoring in SUI symptoms (p = 0.019) and parity status (p = 0.005) and LPL during contraction, factoring in parity status (p = 0.033).

CONCLUSIONS

BDL correlates with BNH, LPL, and LPA with slightly reduced correlation when factoring in parity and continence status. The advantages of the method include accessibility for sensitive populations, nontraditional positions due to the anatomical reference point, functional locations due to limited privacy needs, and minimal training required for pelvic floor therapists to incorporate into rehabilitation.

Development of an e-learning program for biofeedback in pelvic floor muscle training for adult women using self-performed ultrasound: An observational study

INTRODUCTION

Pelvic floor muscle training (PFMT) for urinary incontinence (UI) is recommended in combination with biofeedback to visualize pelvic floor muscles. The focus is on non-invasive hand-held ultrasound (US) measurement methods for PFMT, which can be performed at home. Recently, self-performed US measurements in which the patient applies the US to themself have gradually spreading. This study aimed to develop an educational program for the biofeedback method using self-performed US and to evaluate its feasibility.

METHODS

This study was an observational study. The ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) was utilized to create an e-learning program for women aged ≥40 years with UI. Participants self-performed bladder US via e-learning, using a hand-held US device with a convex probe. The primary outcome was the number of times the bladder area was successfully extracted using an existing automatic bladder area extraction system. The secondary outcome was the total score of the technical evaluation of the self-performed US, which was evaluated across three proficiency levels. Descriptive statistics were conducted for participant characteristics, presenting categorical variables as percentages and continuous variables as means ± SD.

RESULTS

We included 11 participants with a mean age of 56.2 years. Nine participants were able to record US videos, and two were unable to record bladder videos. Regarding the technical evaluation scores, all participants scored ≥80%; four had perfect scores.

CONCLUSIONS

This study showed that transabdominal self-performed bladder US can be performed in 81.8% of women with UI in their 40-60s by using an e-learning program.

How does the pelvic floor respond to modulations in trunk pressure induced by a variety of voicing tasks? A cross-sectional, observational study

The pelvic floor responds to changes in trunk pressure, elevating during low-pressure exhale and descending during high-pressure exhale. Voicing occurs during exhalation, spanning low-to-high trunk-pressure, yet it is unknown how voicing affects the pelvic floor. The aim of this study was to quantify pelvic floor response to voicing and identify if there are differences for women with stress urinary incontinence. We hypothesized that shouting would cause pelvic floor descent, with greater magnitude for incontinent women. Sixty women (38 incontinent, 22 continent) performed four voicing tasks (counting to "4" in speaking/shouting/low-pitch/high-pitch voice) while transperineal ultrasound measured changes in pelvic floor morphology. ANOVA compared variance of responses to voicing and t-tests compared groups. Bladder neck height shortened, levator plate length increased and levator plate angle decreased more during shouting compared to speaking; consistent with pelvic floor straining. There were no differences for high versus low pitch-voicing and small group differences based on continence status. Voicing causes pelvic floor muscles to strain, with greater strain during shouting. Changing vocal pitch does not affect pelvic floor morphology and incontinent women had slight differences from continent women. Voicing may be a safe way to lengthen the pelvic floor without provoking incontinence.

Technologies for Evaluation of Pelvic Floor Functionality: A Systematic Review

Pelvic floor dysfunction is a common problem in women and has a negative impact on their quality of life. The aim of this review was to provide a general overview of the current state of technology used to assess pelvic floor functionality. It also provides literature research of the physiological and anatomical factors that correlate with pelvic floor health. This systematic review was conducted according to the PRISMA guidelines. The PubMed, ScienceDirect, Cochrane Library, and IEEE databases were searched for publications on sensor technology for the assessment of pelvic floor functionality. Anatomical and physiological parameters were identified through a manual search. In the systematic review, 114 publications were included. Twelve different sensor technologies were identified. Information on the obtained parameters, sensor position, test activities, and subject characteristics was prepared in tabular form from each publication. A total of 16 anatomical and physiological parameters influencing pelvic floor health were identified in 17 published studies and ranked for their statistical significance. Taken together, this review could serve as a basis for the development of novel sensors which could allow for quantifiable prevention and diagnosis, as well as particularized documentation of rehabilitation processes related to pelvic floor dysfunctions.

Pelvic floor muscle contraction automatic evaluation algorithm for pelvic floor muscle training biofeedback using self-performed ultrasound

INTRODUCTION

Non-invasive biofeedback of pelvic floor muscle training (PFMT) is required for continuous training in home care. Therefore, we considered self-performed ultrasound (US) in adult women with a handheld US device applied to the bladder. However, US images are difficult to read and require assistance when using US at home. In this study, we aimed to develop an algorithm for the automatic evaluation of pelvic floor muscle (PFM) contraction using self-performed bladder US videos to verify whether it is possible to automatically determine PFM contraction from US videos.

METHODS

Women aged ≥ 20 years were recruited from the outpatient Urology and Gynecology departments of a general hospital or through snowball sampling. The researcher supported the participants in their self-performed bladder US and videos were obtained several times during PFMT. The US videos obtained were used to develop an automatic evaluation algorithm. Supervised machine learning was then performed using expert PFM contraction classifications as ground truth data. Time-series features were generated from the x- and y-coordinate values of the bladder area including the bladder base. The final model was evaluated for accuracy, area under the curve (AUC), recall, precision, and F1. The contribution of each feature variable to the classification ability of the model was estimated.

RESULTS

The 1144 videos obtained from 56 participants were analyzed. We split the data into training and test sets with 7894 time series features. A light gradient boosting machine model (Light GBM) was selected, and the final model resulted in an accuracy of 0.73, AUC = 0.91, recall = 0.66, precision = 0.73, and F1 = 0.73. Movement of the y-coordinate of the bladder base was shown as the most important.

CONCLUSION

This study showed that automated classification of PFM contraction from self-performed US videos is possible with high accuracy.

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

INTRODUCTION

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Accuracy and Reliability of Different Approaches for the Assessment of Pelvic Floor Muscle Strength: A Systematic Review

There had been various methods employed for the evaluation of pelvic floor muscle (PFM) strength. The aim of the study was to do a systemic review of these methods for a better understanding of these techniques and to find the best appropriate method. A systemic review of the literature was done using three databases that included: PubMed, Scopus and Web of Science using the keywords "pelvic floor anatomy" and "functional anatomy of pelvic floor muscles" from 1985 to 2022. All the studies involved were analyzed for the methodologies used by the researcher, advantages, disadvantages, and the conclusion of the study. A total of 1,876 studies were found, out of which only 64 met the criteria of inclusion. In these studies, seven methods were used for the determination of PFM strength. These methods included: clinical palpation, perineometer, electromyography, dynamometer, ultrasonography, magnetic resonance imaging, and vaginal cones. The PFM cannot be calculated accurately using any one measuring technique. There is therefore no "gold standard" approach to PFM assessment. However, combining these methods will result in the best outcomes. According to the literature review, the most often employed procedures were digital palpation, perineometry, and Ultrasonography (USG).

MSK Ultrasound - An IJSPT Perspective

MSK ultrasound is a valuable imaging technique which has become increasingly popular in recent years. This efficient technique proves beneficial in a variety of ways. MSK ultrasound effectively streamlines the process by enabling practitioners to securely and accurately image and assess structures all in one simple step. By allowing healthcare providers to access critical information quickly and conveniently, MSK ultrasound can help identify conditions early when interventions are most effective. Moreover, it may be able to shorten diagnostic times and reduce costs through more cost-effective use of resources such as imaging and laboratory testing. Furthermore, MSK ultrasound can provide additional insights into musculoskeletal anatomy and help improve patient care and outcomes. In addition, utilizing this method reduces exposure to radiation and provides enhanced patient comfort with its quick scan duration. MSK ultrasound has a high potential to provide quick and accurate diagnosis of MSK disturbances when used correctly. As clinicians become more comfortable and familiar with this technology, we will continue to see its use expand for various MSK assessments. In this commentary we'll explore how ultrasound can be used in physical therapy, specifically for musculoskeletal assessment. We'll also look at some of the potential benefits and limitations of using ultrasound in PT practice.

Effects of Adding Ultrasound Biofeedback to Individualized Pelvic Floor Muscle Training on Extensibility of the Pelvic Floor Muscle and Anterior Pelvic Organ Prolapse in Postmenopausal Women

The aim of the study was to determine effects of adding transperineal ultrasound (TPUS) biofeedback to individualized pelvic floor muscle training (PFMT) on extensibility of the pelvic floor muscle and anterior pelvic organ prolapse (POP) in postmenopausal women. A total of 77 patients with POP at stage I or stage II were admitted to Beijing Shijitan Hospital, China, from January 2017 to October 2018. They were randomly divided into a control group (CG) (n = 37) or a study group (SG) (n = 40). Both SG and CG received a 12-week PFMT including health education, verbal instruction, and home training. However, the SG, but not the CG, received additional TPUS biofeedback. Data of these patients were retrospectively reviewed. The distance from the lowest point of the bladder to the inferior-posterior margin of the symphysis pubis (BSP) and the levator hiatus area (LHA) were measured on maximal Valsalva via TPUS before and after the 12-week PFMT. Correct pelvic floor muscle contraction (PFMC) rates before and after PFMT were compared between the two groups. The correct PFMC rate was higher in the SG than that in the CG (92.5% vs. 73%; x² = 5.223, p=0.022). The BSP was increased but the LHA was reduced after the 12-week PFMT in both groups compared to those before PFMT (all p < 0.05). However, after the PFMT, the SG showed greater improvement than the CG for both BSP (0.77 ± 0.71 cm vs. 0.11 ± 0.66 cm, p < 0.05) and LHA (20.69 ± 2.77 cm² vs. 22.85 ± 3.98 cm², p < 0.05). TPUS might be an effective biofeedback tool for PFMT in clinical practice. Individualized PFMT with TPUS biofeedback could significantly attenuate POP severity and strengthen the extensibility of pelvic floor muscle in postmenopausal women when they are under increased intraabdominal pressure.

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.

[Pelvic floor disorders: What do adolescents and young women know? A literature review]

AIM

To assess the knowledge of adolescent girls and young women on pelvic-perineal disorders (PPD).

METHOD

We searched on PubMed, Cochrane Library, Kinédoc and Semantic Scholar databases using the MeSH keywords: "knowledge" "awareness" "surveys" "young women" "pelvic floor" "adolescent" "teenager" "athletic injury" "urinary incontinence". The articles had to have been published within the last 15 years, written in French or English, and deal with the state of knowledge of adolescents and young women concerning the perineal sphere using questionnaires.

RESULTS

A total of 8 studies were included in the review, 5 cross-sectional studies and 3 intervention studies. The knowledge of adolescent girls and young women interviewed about the anatomy of the pelvic floor, its function, and risk factors for PPD was low. The majority of the participants wanted more information about the pelvic floor. Two studies that conducted an educational intervention showed a significant improvement in knowledge.

CONCLUSION

Knowledge of pelvic-perineal disorders and pelvic floor function is poor in adolescent girls and young women. To better assess them, it would be necessary to validate a questionnaire containing all the items about knowledge.

An International Continence Society (ICS) report on the terminology for pelvic floor muscle assessment

INTRODUCTION

The terminology for female and male pelvic floor muscle (PFM) assessment has expanded considerably since the first PFM function and dysfunction standardization of terminology document in 2005. New terms have entered assessment reports, and new investigations to measure PFM function and dysfunction have been developed. An update of this terminology was required to comprehensively document the terms and their definitions, and to describe the assessment method and interpretation of the finding, to standardize assessment procedures and aid diagnostic decision making.

METHODS

This report combines the input of members of the Standardisation Committee of the International Continence Society (ICS) Working Group 16, with contributions from recognized experts in the field and external referees. A logical, sequential, clinically directed assessment framework was created against which the assessment process was mapped. Within categories and subclassifications, each term was assigned a numeric coding. A transparent process of 12 rounds of full working group and external review was undertaken to exhaustively examine each definition, plus additional extensive internal development, with decision making by collective opinion (consensus).

RESULTS

A Terminology Report for the symptoms, signs, investigations, and diagnoses associated with PFM function and dysfunction, encompassing 185 separate definitions/descriptors, has been developed. It is clinically based with the most common assessment processes defined. Clarity and user-friendliness have been key aims to make it interpretable by clinicians and researchers of different disciplines.

CONCLUSION

A consensus-based Terminology Report for assessment of PFM function and dysfunction has been produced to aid clinical practice and be a stimulus for research.

Characterizing Pelvic Floor Muscle Function and Morphometry in Survivors of Gynecological Cancer Who Have Dyspareunia: A Comparative Cross-Sectional Study

OBJECTIVE

More than one-half of gynecological cancer survivors are affected by pain during sexual intercourse, also known as dyspareunia. Oncological treatments may result in pelvic floor muscle (PFM) alterations, which are suspected to play a key role in dyspareunia. However, to our knowledge, no study has investigated PFM function and morphometry in this population. The aim of the study was to characterize and compare PFM function and morphometry between gynecological cancer survivors with dyspareunia and asymptomatic women.

METHODS

Twenty-four gynecological cancer survivors with dyspareunia and 32 women with a history of total hysterectomy but without pelvic pain (asymptomatic women) participated in this comparative cross-sectional study. PFM passive forces (tone), flexibility, stiffness, maximal strength, coordination, and endurance were assessed with an intra-vaginal dynamometric speculum. Bladder neck position, levator plate angle, anorectal angle, and levator hiatal dimensions were measured at rest and on maximal contraction with 3D/4D transperineal ultrasound imaging.

RESULTS

Compared with asymptomatic women, gynecological cancer survivors showed heightened PFM tone, lower flexibility, higher stiffness, and lower coordination and endurance. At rest, they had a smaller anorectal angle and smaller levator hiatal dimensions, indicating heightened PFM tone. They also presented fewer changes from rest to maximal contraction for anorectal angle and levator hiatal dimensions, suggesting an elevated tone or altered contractile properties.

CONCLUSIONS

Gynecological cancer survivors with dyspareunia present with altered PFM function and morphometry. This research therefore provides a better understanding of the underlying mechanisms of dyspareunia in cancer survivors.

IMPACT

Our study confirms alterations in PFM function and morphometry in gynecological cancer survivors with dyspareunia. These findings support the rationale for developing and assessing the efficacy of physical therapy targeting PFM alterations in this population.

Intrasession Real-time Ultrasonography Feedback Improves the Quality of Transverse Abdominis Contraction

OBJECTIVE

The purpose of this study was to compare changes in thickness of the transverse abdominis during performance of the hollowing exercise guided by feedback using ultrasonography images together with verbal guidance and using verbal guidance alone. We also determined the minimal detectable change and agreement between normalized pressures and muscle thickness.

METHODS

Twenty participants without lumbar pain performed the hollowing exercises with or without ultrasonography feedback: 7 men and 13 women, mean (SD) age = 25 (5) years, height = 166 (10) cm, body mass = 64 (6) kg, body mass index = 22.2 (5.8) kg/m². The thickness of the transverse abdominis was quantified during the exercise using musculoskeletal ultrasonography. Basal and 3 repetitions guided by an evaluator were performed. Pressure was determined using a lumbar cushion. Data were compared with a mixed-model analysis of variance and Bonferroni post hoc test (P < .05). Minimal detectable changes were identified and Bland-Altman analysis performed considering normalized thickness and pressure.

RESULTS

Ultrasonography feedback resulted in larger thickness changes (P < .05). The lowest minimal detectable changes were achieved using ultrasonography feedback. Nonagreement was found between normalized thickness and pressure.

CONCLUSION

Contraction of the transverse abdominis is improved using real-time ultrasonography together with verbal feedback. Low changes in muscle contraction estimated by thickness showed nonagreement with a pressure cushion.

Novel insight into the coordination between pelvic floor muscles and the glottis through ultrasound imaging: a pilot study

INTRODUCTION

Pelvic floor physical therapists have long utilized breathing cues with exercises and are beginning to incorporate vocalization tasks. To date, there have been no publications describing pelvic floor displacement during vocalization tasks. This study is a preliminary investigation into the changes in bladder shape distortion as a proxy for pelvic floor muscle displacement during respiratory and phonatory tasks.

METHODS

Bladders were imaged using two-dimensional ultrasound in standing position. Measurement consisted of a diagonal line from the most anterior-superior aspect of the bladder to the most inferior-posterior aspect of the bladder. Length was measured at baseline and maximum distortion for each task. The first two tasks cued pelvic floor muscles to contract and then strain. Subsequent tasks only cued glottis function. A linear regression tested correlation between bladder distortion response to glottis tasks and cued pelvic floor tasks. The hypothesis was that diagonal would shorten with contraction, lengthen with strain, and follow a similar pattern seen in respiration for phonation tasks.

RESULTS

Ten asymptomatic participants (5 men, 5 women) showed bladder diagonal shortening when cuing pelvic floor contraction for all participants and lengthening for 7 of the 10 participants when cued to strain the pelvic floor. The response of bladder length change was variable for glottis tasks, trending toward lengthening and significantly different in response to contraction.

CONCLUSIONS

When cuing pelvic floor to contract, healthy individuals showed shortening of bladder length and most lengthened during strain. When cuing phonation and respiration tasks, there was a tendency toward bladder lengthening.

Ability to contract the pelvic floor muscles and association with muscle function in incontinent women

INTRODUCTION AND HYPOTHESIS

Many women with pelvic floor dysfunction are unable to perform pelvic floor muscle (PFM) contraction. We aimed to assess the ability to contract the PFM and to evaluate the association with muscle function in Brazilian women with urinary incontinence.

METHODS

We conducted a retrospective cross-sectional study including incontinent women over the age of 18. The assessment of PFM contraction was carried out by bidigital palpation via the PERFECT scheme. We categorized our population as: group absent: women not able to contract the PFM with verbal instructions; group 1 (1st command): women able to contract their PFM after verbal instructions; group 2 (2nd command): women who needed additional training on PFM anatomy and functioning to contract them. We compared the groups regarding their PFM functionality. We used ANOVA for demographic data and Mann-Whitney test for association analyses and P value < 0.05 for statistical significance.

RESULTS

Among 139 women included, 21 (15.1%) were not able to perform the contraction of the PFM. Sixty-five (46.7%) contracted their PFM voluntarily at the first command and 53 (38.1%) at the second command. There was a significant reduction in the PFM function in group 2 in terms of power (p < 0.001), endurance (p < 0.001) and fast contraction (p < 0.001) compared to group 1.

CONCLUSION

A high percentage (53.2%) of women were not able to contract their PFM voluntarily without training in PFM anatomy and functioning. Those women had impaired muscle function compared to women able to perform PFM after receiving exclusively oral instructions.

The Overactive Pelvic Floor (OPF) and Sexual Dysfunction. Part 2: Evaluation and Treatment of Sexual Dysfunction in OPF Patients

INTRODUCTION

The assessment of pelvic floor muscle (PFM) overactivity is part of a comprehensive evaluation including a detailed history (medical, gynecological history/antecedent), appraisal of the psychosocial contexts of the patient, as well as a musculoskeletal and a neurological examination.

OBJECTIVES

The aims of this article are to review (i) the assessment modalities evaluating pelvic floor function in women and men with disorders associated with an overactive pelvic floor (OPF), and (ii) therapeutic approaches to address OPF, with particular emphases on sexual pain and function.

METHODS

We outline assessment tools that evaluate psychological and cognitive states. We then review the assessment techniques to evaluate PFM involvement including digital palpation, electromyography, manometry, ultrasonography, and dynamometry, including an overview of the indications, efficacy, advantages, and limitations of each instrument. We consider each instrument's utility in research and in clinical settings. We next review the evidence for medical, physiotherapy, and psychological interventions for OPF-related conditions.

RESULTS

Research using these assessment techniques consistently points to findings of high PFM tone among women and men reporting disorders associated with OPF. While higher levels of evidence are needed, options for medical treatment include diazepam suppositories, botulinum toxin A, and other muscle relaxants. Effective psychological therapies include cognitive behavioral therapy, couple therapy, mindfulness, and educational interventions. Effective physiotherapy approaches include PFM exercise with biofeedback, electrotherapy, manual therapy, and the use of dilators. Multimodal approaches have demonstrated efficacy in reducing pain, normalizing PFM tone, and improving sexual function. Multidisciplinary interventions and an integrative approach to the assessment and management of OPF using a biopsychosocial framework are discussed.

CONCLUSION

Although the efficacy of various intervention approaches has been demonstrated, further studies are needed to personalize interventions according to a thorough assessment and determine the optimal combination of psychological, physical, and behavioral modalities.

Transperineal Ultrasound Visual Feedback Assisted Pelvic Floor Muscle Physiotherapy in Women With Deep Infiltrating Endometriosis and Dyspareunia: A Pilot Study

A prospective study with the aim to evaluate the effects of pelvic floor physiotherapy was conducted among women with deep infiltrating endometriosis (DIE) and associated dyspareunia. At initial evaluation superficial and deep dyspareunia were assessed using a numerical rating scale, and levator hiatus area (LHA) was assessed with 3-D/4-D transperineal ultrasound. Women underwent five individual sessions of ultrasound visual feedback assisted pelvic floor physiotherapy. One month after the therapy, dyspareunia and LHA were reassessed and compared with pre-therapy data. Pelvic floor physiotherapy seems to improve both superficial and deep dyspareunia and pelvic floor muscle relaxation in women with DIE.

Development of a wireless accelerometer-based Intravaginal device to detect pelvic floor motion for evaluation of pelvic floor dysfunction

Urinary incontinence (UI) is experienced by an estimated 51% of women in the U.S. and often results from impaired function or weakening of the pelvic floor muscles. Pelvic floor muscle training (PFMT) is a frontline nonsurgical treatment, yet a number of symptomatic individuals cannot accurately perform a pelvic floor muscle contraction with simple verbal or written instruction. Long-term adherence to PFMT regimens is often a barrier to resolution of symptoms. Various biofeedback tools have been utilized to aid correct pelvic floor muscle performance and adherence. One novel device, the leva® Pelvic Digital Health System, utilizes an intravaginal probe embedded with MEMS accelerometer sensors that allow real-time visualization of the shape and motion of the vagina during PFMT. Early positive results with this device prompted design of a wearable version. The purpose of this study was to design a wearable, wireless clinical research device to optimize MEMS accelerometer sensor placement to detect maximal movement during a pelvic floor muscle exercise (PFME) and to test the form factor for retention and user acceptability. The device comprised a ring designed to sit at the fornix with an extension following the length of the vagina. This paper presents design components and results from clinical testing of 10 subjects. It was determined that a ring form factor alone, similar to other vaginal rings (pessaries, estrogen rings) provided less accurate visual information about PFME performance. By contrast, we determined that a ring with an extension allowed for device retention and improved real-time detection of vaginal shape and motion during PFMT.

[Benefits of pelvic floor education in perineal re-education in women]

AIM

Evaluate the impact of pelvic floor education on the symptoms of female patients referred for pelvic floor muscle training (PFMT).

METHODS

Forty female patients suffering from pelvic floor disorders and referred to independent practice for PFME between February and May 2019 answered a survey on symptoms and quality of life before PFME, after four sessions of pelvic floor education and at the end of PFME. The ICIQ-SF, USP, Contilife, PDFI 20, Kess, and Wexner scores were used to evaluate the results. The protocol consisted in four initial sessions of pelvic floor education including information on each field of perineology ; the fifth session was dedicated to visual feedback using a mirror ; the following five sessions were tailored according to the care objectives established based on the initial assessment.

RESULTS

The scores were significantly improved after the four initial sessions of pelvic floor education. The improvement was significant at the end of the re-education program. The PFDI-20 score dropped from 66,9 to 20,9 (P=0,002), the ICIQ-SF score from 8,4 to 1,5 (P<10^-3), the Wexner score from 7,4 to 5,1 (P<10^-3) and the Kess score from 14,2 to 8,7 (P=0,05).

CONCLUSION

The results showed that female patients undergoing perineal re-education including pelvic floor education sessions show a significant improvement in their symptoms already immediately after the pelvic floor education sessions.

Ultrasound assessment of pelvic floor muscle contraction: reliability and development of an ultrasound-based contraction scale

OBJECTIVES

To determine intra- and interrater reliability and agreement for ultrasound measurements of pelvic floor muscle contraction and to assess the correlation between ultrasound and vaginal palpation. We also aimed to develop an ultrasound scale for assessment of pelvic floor muscle contraction.

METHODS

This was a cross-sectional study of 195 women scheduled for stress urinary incontinence (n = 65) or prolapse (n = 65) surgery or who were primigravid (n = 65). Pelvic floor muscle contraction was assessed by vaginal palpation using the Modified Oxford Scale (MOS) and by two- and three-dimensional (2D/3D) transperineal ultrasound. Proportional change in 2D and 3D levator hiatal anteroposterior (AP) diameter and 3D levator hiatal area between rest and contraction were used as measures of pelvic floor muscle contraction. One rater repeated all ultrasound measurements on stored volumes, which were used for intrarater reliability and agreement analysis, and three independent raters analyzed 60 ultrasound volumes for interrater reliability and agreement analysis. Reliability was assessed using the intraclass correlation coefficient (ICC) and agreement using Bland-Altman analysis. Tomographic ultrasound was used to identify women with major levator injury. Spearman's rank correlation coefficient (r_S ) was used to assess the correlation between ultrasound measurements of pelvic floor muscle contraction and MOS score. The proportion of women allocated to each category of muscle contraction (absent, weak, moderate or strong) by palpation was used to determine the cut-offs for the ultrasound scale.

RESULTS

Intrarater ICC was 0.81 (95% CI, 0.74-0.85) for proportional change in 2D levator hiatal AP diameter. Interrater ICC was 0.82 (95% CI, 0.72-0.89) for proportional change in 2D AP diameter, 0.80 (95% CI, 0.69-0.88) for proportional change in 3D AP diameter and 0.72 (95% CI, 0.56-0.83) for proportional change in hiatal area. The prevalence of major levator injury was 22.6%. The strength of correlation (r_S ) between ultrasound measurements and MOS score was 0.52 for 2D AP diameter, 0.62 for 3D AP diameter and 0.47 for hiatal area (P < 0.001 for all). On the ultrasound contraction scale, proportional change in 2D levator hiatal AP diameter of < 1% corresponds to absent, 2-14% to weak, 15-29% to normal and > 30% to strong contraction.

CONCLUSIONS

Ultrasound seems to be an objective and reliable method for evaluation of pelvic floor muscle contraction. Proportional change in 2D levator hiatal AP diameter had the highest ICC and moderate correlation with MOS score assessed by vaginal palpation, and we constructed an ultrasound scale for assessment of pelvic floor muscle contraction based on this measure.

Pelvic floor rehabilitation in children with functional LUTD: does it improve outcome?

INTRODUCTION

If children do not experience satisfactory relief of lower urinary tract dysfunction (LUTD) complaints after standard urotherapy is provided, other treatment options need to be explored. To date, little is known about the clinical value of pelvic floor rehabilitation in the treatment of functional voiding disorders.

OBJECTIVE

Therefore, we compared pelvic floor rehabilitation by biofeedback with anal balloon expulsion (BABE) to intensive urotherapy in the treatment of children with inadequate pelvic floor control and functional LUTD.

STUDY DESIGN

A retrospective chart study was conducted on children with functional incontinence and inadequate pelvic floor control. All children referred for both intensive inpatient urotherapy and pelvic floor rehabilitation between 2010 and 2018 were considered for inclusion. A total of 52 patients were eligible with 25 children in the group who received BABE before inpatient urotherapy, and 27 children in the group who received BABE subsequently to urotherapy. Main outcome measurement was treatment success according to International Children's Continence Society criteria measured after treatment rounds and follow-up.

RESULTS

Baseline characteristics demonstrate no major differences between the BABE and control group. There was a significant difference in improvement between BABE and inpatient urotherapy after the first and second round of treatment (round 1: BABE vs urotherapy; 12% vs 70%, respectively, round 2: urotherapy vs BABE; 92% vs 34%, respectively, both P < .001). In both cases, the urotherapy group obtained greater results (Fig. 1). When the additional effect of BABE on urotherapy treatment is assessed, no significant difference is found (P = .355) in the children who received BABE; 30 (58%) showed improvement on pelvic floor control.

DISCUSSION

Our findings imply that training pelvic floor control in combination with inpatient urotherapy does not influence treatment effectiveness on incontinence. Intensive urotherapy contains biofeedback by real-time uroflowmetry; children receive direct feedback on their voiding behaviour. Attention offered to the child and achieving cognitive maturity with corresponding behaviour is of paramount importance. It is known that combining several kinds of biofeedback does not enhance the outcome. However, our results do not provide a conclusive answer to the effectiveness of pelvic floor physical therapy in the treatment of children with LUTD because we specifically investigated BABE.

CONCLUSION

In this study, we could not prove that pelvic floor rehabilitation by BABE has an additional effect on inpatient urotherapy on incontinence outcomes. Considering the invasive nature of BABE, the use of BABE to obtain continence should therefore be discouraged.

Magnetic resonance imaging and 3-dimensional transperineal ultrasound evaluation of pelvic floor dysfunction in symptomatic women: a prospective comparative study

Purpose

The purpose of this study was to investigate magnetic resonance imaging (MRI) and 3-dimensional transperineal ultrasound (3D-TPUS) features of pelvic floor dysfunction (PFD) in symptomatic women in correlation with digital palpation and to define cut-offs for hiatal dimensions predictive of muscle dysfunction.

Methods

This prospective study included 73 women with symptoms suggesting PFD. 3D-TPUS, MRI, and digital palpation of the levator ani muscle were performed in all patients. Levator hiatal antero-posterior (LHap) diameter and area (LH area) were measured at rest and at maximum muscle contraction.

Results

The reduction in LHap diameter and LH area during contraction was significantly less in women with underactive pelvic floor muscle contraction (UpfmC) than in those who had normal pelvic floor muscle contraction by digital palpation (P<0.001). Statistically significant positive correlations (P<0.001) were found between the Modified Oxford Score and 3D-TPUS and MRI regarding the reduction in the LHap diameter (r=0.80 and r=0.82, respectively) and LH area (r=0.60 and r=0.70, respectively). A reduction in LHap of <6.5% on 3D-TPUS and <7.6% on MRI predicted UpfmC with sensitivities of 46.2% and 82.7%, respectively. A reduction in LH area of <3.4% on 3D-TPUS and <3.8% on MRI predicted UpfmC with sensitivities of 75.0% and 88.5%, respectively. MRI was more sensitive in detecting levator avulsion (63.4%) than 3D-TPUS (27.1%).

Conclusion

MRI and 3D-TPUS had strong positive correlations with findings on palpation, and at certain cut-offs for hiatal dimensions, they can be used as complementary and objective tools to improve the accuracy of diagnosis and management planning of PFD.

Evaluation of an accelerometer-based digital health system for the treatment of female urinary incontinence: A pilot study

Aims

To assess the effectiveness and patient satisfaction of pelvic floor muscle training (PFMT) guided by an intravaginal accelerometer‐based system for the treatment of female urinary incontinence (UI).

Methods

Premenopausal women with mild‐to‐moderate stress or mixed UI were recruited to participate in PFMT with an accelerometer‐based system for 6 weeks with supervision. Objective outcomes included pelvic floor muscle (PFM) contraction duration, number of contractions in 15 seconds, and angular displacement of the accelerometer relative to earth during PFM contraction. Subjective outcomes and quality‐of‐life were assessed with validated, condition‐specific questionnaires. Results are presented as means, standard error of the mean, and 95% confidence intervals unless otherwise indicated.

Results

Twenty‐three women (age 42.0 ± 10.7 years, mean ± standard deviation) completed the study. Scores on the Urogenital Distress Inventory (UDI) decreased from 36.7 ± 4.7 at baseline to 1.45 ± 0.8 at 6 weeks (P < .0001). The Patient's Global Impression of Severity score decreased from 1.5 ± 0.1 to 0.2 ± 0.1 (P < .0001) at study endpoint. At 6 weeks, the PFM contraction duration increased from 13 ± 2.6 at baseline to 187 ± 9.6 seconds (P < .0001). Repeated contractions in 15 seconds increased from 5.9 ± 0.4 at enrollment to 9.6 ± 0.5 at 6 weeks (P < .0001). Maximum pelvic floor angle (a measure of lift) increased from 65.1 ± 2.0° to 81.1 ± 1.8° (P < .0001). Increasing PFM contraction duration and maximum pelvic floor angle correlated with decreasing UDI‐6 scores, r = −0.87, P = .01; r = −0.97, P = .0003, respectively. No device‐related adverse events occurred.

Conclusions

Pilot testing of this accelerometer‐based system demonstrates improvements in objective PFM measures, patient‐reported UI severity and condition‐specific quality of life, with results evident after 1 week of use.

Imaging with ultrasound in physical therapy: What is the PT's scope of practice? A competency-based educational model and training recommendations

Physical therapists employ ultrasound (US) imaging technology for a broad range of clinical and research purposes. Despite this, few physical therapy regulatory bodies guide the use of US imaging, and there are limited continuing education opportunities for physical therapists to become proficient in using US within their professional scope of practice. Here, we (i) outline the current status of US use by physical therapists; (ii) define and describe four broad categories of physical therapy US applications (ie, rehabilitation, diagnostic, intervention and research US); (iii) discuss how US use relates to the scope of high value physical therapy practice and (iv) propose a broad framework for a competency-based education model for training physical therapists in US. This paper only discusses US imaging—not ‘therapeutic’ US. Thus, ‘imaging’ is implicit anywhere the term ‘ultrasound’ is used.

Changes in the contraction ratio of transversus abdominis and quality of life in patients after total hip replacement and three-compartment knee arthroplasty with implant posterior stabilization

Core stability is a reference term for the performance of the deep trunk muscles, which provide functional stability of the lumbopelvic area and control the human body in static and dynamic positions. The study group consisted of 30 patients between the age of 42 and 76 years (mean=61.4) after total hip arthroplasty (total hip replacement, Group I) and total knee arthroplasty (three-compartment arthroplasty with posterior stabilization of the implant - Group II). In 18 (60%) patients, hip endoprosthesis was performed, whereas in 12 (40%), three-compartment knee endoprosthesis with posterior stabilization has been implanted. In the study group, Rehabilitative Ultrasound Imaging (RUSI) of the transversus abdominis muscle thickness was conducted at rest and in contraction, the transversus abdominis activation ratio was specified, the SF-36 Life Quality Questionnaire was applied and a three-week treatment cycle was performed. The tests were carried out twice, i.e. before and after treatment. In the group of patients after total hip replacement, the transversus abdominis (TrA) contraction ratio before the beginning of the exercise programme was 0.79±0.06, and after its completion 0.9 ±0.02. The observed difference was statistically significant at p<0.001. In the group of patients after three-compartment knee arthroplasty, the TrA contraction ratio before the beginning of the exercise programme was 0.78±0.09, and after its completion0 0.91±0.02. The difference of these values was statistically significant at the level of p<0.05. The results of the SF-36 questionnaire in both groups indicate improvement in physical functioning. The observed difference was statistically significant at p<0.001. The performed three-week physiotherapy treatment in conjunction with deep muscle training increases the thickness of the TrA muscle during rest and contraction testing, and increases the transversus abdominis contraction ratio in Rehabilitative Ultrasound Imaging in the study groups. Furthermore, improvement in the level of physical functioning was observed within the studied groups.

Ultrasound in the assessment of pelvic organ prolapse

Imaging is increasingly being used in urogynaecology. Because of low cost and universal availability, ultrasound (US) is the most commonly used diagnostic modality, which allows the observation of manoeuvres such as Valsalva and pelvic floor muscle contraction in real time. The ability to see beyond surface anatomy is particularly important in the posterior compartment and in obstructed defecation where this method may replace defecation proctography. Imaging is especially useful in the form of 3D/4D multiplanar and tomographic translabial US, as these modalities give access to the axial plane and the levator ani. This allows assessment of both avulsion, i.e. major maternal birth trauma, and hiatal overdistension, i.e. ballooning. Both are major risk factors for both prolapse and prolapse recurrence. This review will outline current clinical utility, introduce recent research in the respective field and provide an overview of likely future utility of imaging in the investigation of pelvic organ prolapse.

Pelvic Floor Morphometric Differences in Elderly Women with or without Urinary Incontinence

Purpose: Urinary incontinence (UI) affects as many as 50% of women aged 60 years and older, but UI pathophysiology, specifically in elderly women, remains unclear. A better understanding of morphometric differences between continent and urinary incontinent elderly women is needed to improve the effectiveness of conservative treatment approaches. We hypothesized that morphometric differences in the pelvic floor muscles (PFM) among elderly women with and without UI could be observed using three- and four-dimensional (3D/4D) transperineal ultrasound (TPU) imaging. Method: A total of 40 elderly women (20 women with and 20 women without UI), with a mean age of 67.10 (SD 4.94) years, participated in the study. This was a case-control study in which TPU images were taken under three conditions: rest, maximal voluntary contraction (MVC), and Valsalva. Independent t-tests were conducted to compare measurements between the groups. Results: The study revealed statistically significant differences between the groups. At rest, the levator hiatal area and transverse diameter were bigger, and the PFM position was lower in the incontinent group. During MVC, all axial plane parameters were bigger in the incontinent group. In the sagittal plane, PFM position was again lower in the incontinent group. During Valsalva, the anorectal angle was wider in the women with incontinence. Conclusion: PFM morphometric differences were present and were observed using 3D/4D TPU imaging in elderly women with and without UI.

Can we evaluate the levator ani after Kegel exercise in women with pelvic organ prolapse by transperineal elastography? A preliminary study

OBJECTIVES

The aim of this study was to evaluate the stiffness variation of the levator ani in patients with stage I/II pelvic organ prolapse (POP) before and after Kegel exercises by transperineal elastography.

METHODS

A total of 20 patients who were diagnosed with staged I/II POP underwent conventional transperineal ultrasound and elastography. For each patient, the levator ani was located and evaluated in the state of Valsalva. After Kegel exercises for 12 weeks, transperineal ultrasound and elastography were repeated. The elasticity images were assessed using a four-point scale scoring system.

RESULTS

Of the 20 cases, four had an elastography score of 1, 14 had a score of 2, two had a score of 3, and no cases had a score of 4 in the levator ani before Kegel exercises. After Kegel exercises, one had an elastography score of 1, two had a score of 2, 15 had a score of 3, and two cases had a score of 4. The mean elastography score was statistically significantly higher for the levator ani after Kegel exercises (2.90 ± 0.48) than for the baseline score (1.90 ± 0.29) (p = 0.025).

CONCLUSIONS

Transperineal elastography was an effective and useful tool in the evaluation of the levator ani in patients with POP-Q stage I/II before and after Kegel exercises.

Effects of a facilitating device on pelvic floor muscle contraction during breathing exercises

[Purpose] This study aimed to clarify the effects and to verify the efficacy of various breathing exercises performed while sitting on a small foam roller on the contraction of pelvic floor muscles in males. [Participants and Methods] This study, involving 10 healthy males (age 19.9 ± 1.6 years), had a crossover design and involved two conditions: sitting at rest for 10 min (CON condition) and sitting on a small foam roller placed on a chair while performing seven breathing exercises (EXE condition). Movement of the posterior side of the bladder was examined in both conditions using ultrasonic imaging. Pelvic floor muscle contraction was evaluated based on the movement distance. [Results] No significant difference was found in any parameter for CON conditions. The distance of bladder posterior side movement was 5.58 ± 2.51 mm (pre), 13.66 ± 5.16 mm (post), and 9.59 ± 3.67 mm (post-1 month) for EXE conditions. Subjective evaluation also demonstrated that the feeling of contraction was stronger immediately after the experiment. [Conclusion] Results demonstrated that various breathing exercises, performed while sitting on a small foam roller, enhanced the voluntary contraction of pelvic floor muscles in males. Efficacy was demonstrated, at least in young males.

Review article: dyssynergic defaecation and biofeedback therapy in the pathophysiology and management of functional constipation

BACKGROUND

Functional constipation is a common clinical presentation in primary care. Functional defaecation disorders are defined as the paradoxical contraction or inadequate relaxation of the pelvic floor muscles during attempted defaecation (dyssynergic defaecation) and/or inadequate propulsive forces during attempted defaecation. Prompt diagnosis and management of dyssynergic defaecation is hindered by uncertainty regarding nomenclature, diagnostic criteria, pathophysiology and efficacy of management options such as biofeedback therapy.

AIM

To review the evidence pertaining to the pathophysiology of functional defaecation disorders and the efficacy of biofeedback therapy in the management of patients with dyssynergic defaecation and functional constipation.

METHODS

Relevant articles addressing functional defaecation disorders and the efficacy of biofeedback therapy in the management of dyssynergic defaecation and functional constipation were identified from a search of Pubmed, MEDLINE Ovid and the Cochrane Library.

RESULTS

The prevalence of dyssynergic defaecation in patients investigated for chronic constipation is as many as 40%. Randomised controlled trials have demonstrated major symptom improvement in 70%-80% of patients undergoing biofeedback therapy for chronic constipation resistant to standard medical therapy and have determined it to be superior to polyethylene glycol laxatives, diazepam or sham therapy. Long-term studies have shown 55%-82% of patients maintain symptom improvement.

CONCLUSIONS

Dyssynergic defaecation is a common clinical condition in patients with chronic constipation not responding to conservative management. Biofeedback therapy appears to be a safe, successful treatment with sustained results for patients with dyssynergic defaecation. Further studies are required to standardise the diagnosis of dyssynergic defaecation in addition to employing systematic protocols for biofeedback therapy.

Traditional Gymnastic Exercises for the Pelvic Floor Often Lead to Bladder Neck Descent - a Study Using Perineal Ultrasound

BACKGROUND

The aims of physiotherapy in stress incontinent women are to improve pelvic floor function and the continence mechanism including bladder neck support and urethral closure pressure. In Germany, traditional conservative treatment often includes gymnastic exercises with unclear effects on the bladder neck. The aim of this study was to sonographically assess bladder neck movements during selected exercises.

METHODS

Fifteen healthy, continent women without previous vaginal births, who were able to voluntarily contract their pelvic floor muscels performed the shoulder bridge, the abdominal press, tiptoe and the Pilates clam exercises. The first set was performed without any additional instructions. During the second set directions were given to activate the pelvic floor before beginning each exercise and to maintain the contraction throughout the exercise. Bladder neck movement was measured on perineal ultrasound using a validated method with the pubic symphysis as a reference point.

RESULTS

The median age of participants was 32 years, median BMI was 23. Eight women were nulliparous and seven had given birth to 1 - 2 children via caesarean section. When exercises were performed without voluntary pelvic floor contraction the bladder neck descended on average between 2.3 and 4.4 mm, and with pelvic floor contraction prior to the exercise only between 0.5 and 2.1 mm (p > 0.05 except for abdominal press p = 0.007). The Pilates clam exercise and toe stand stabilised the bladder neck most effectively.

DISCUSSION

Bladder neck descent often occurs during pelvic floor gymnastic exercises as traditionally performed in Germany, and a voluntary pelvic floor contraction during the exercises does not necessarily prevent this.

Pelvic floor morphometry and function in women with and without puborectalis avulsion in the early postpartum period

BACKGROUND

Pelvic floor muscles are subject to considerable stretching during vaginal birth. In 13-36% of women, stretching results in avulsion injury whereby the puborectalis muscle disconnects from its insertion points on the pubis bone. Until now, few studies have investigated the effect of this lesion on pelvic floor muscles in the early postpartum period.

OBJECTIVE

The primary aim of this study was to compare pelvic floor muscle morphometry and function in primiparous women with and without puborectalis avulsion in the early postpartum period. Our secondary objective was to compare the 2 groups for pelvic floor disorders and impact on quality of life.

STUDY DESIGN

In all, 52 primiparous women diagnosed with (n = 22) or without (n = 30) puborectalis avulsion injury were assessed at 3 months postpartum. Pelvic floor muscle morphometry was evaluated with 3-/4-dimensional transperineal ultrasound at rest, maximal contraction, and Valsalva maneuver. Different parameters were measured in the midsagittal and axial planes: bladder neck position, levator plate angle, anorectal angle, and levator hiatus dimensions. The dynamometric speculum was used to assess pelvic floor muscle function including: passive properties (passive forces and stiffness) during dynamic stretches, maximal strength, speed of contraction, and endurance. Pelvic floor disorder-related symptoms (eg, urinary incontinence, vaginal and bowel symptoms) and impact on quality of life were evaluated with the International Consultation on Incontinence Questionnaire and the Pelvic Floor Impact Questionnaire-Short Form. Pelvic Organ Prolapse Quantification was also assessed.

RESULTS

In comparison to women without avulsion, women with avulsion presented an enlarged hiatus area at rest, maximal contraction, and Valsalva maneuver (P ≤ .013) and all other ultrasound parameters were found to be significantly altered during maximal contraction (P ≤ .014). They showed lower passive forces at maximal and 20-mm vaginal apertures as well as lower stiffness at 20-mm aperture (P ≤ .048). Significantly lower strength, speed of contraction, and endurance were also found in women with avulsion (P ≤ .005). They also presented more urinary incontinence symptoms (P = .040) whereas vaginal and bowel symptoms were found to be similar in the 2 groups. Pelvic Organ Prolapse Quantification revealed greater anterior compartment descent in women with avulsion (P ≤ .010). The impact of pelvic floor disorders on quality of life was found to be significantly higher in women with avulsion (P = .038).

CONCLUSION

This study confirms that pelvic floor muscle morphometry and function are impaired in primiparous women with puborectalis avulsion in the early postpartum period. Moreover, it highlights specific muscle parameters that are altered such as passive properties, strength, speed of contraction, and endurance.

Diagnosis and Therapy of Female Pelvic Organ Prolapse. Guideline of the DGGG, SGGG and OEGGG (S2e-Level, AWMF Registry Number 015/006, April 2016)

Aims: The aim was to establish an official interdisciplinary guideline, published and coordinated by the German Society of Gynecology and Obstetrics (DGGG). The guideline was developed for use in German-speaking countries. In addition to the Germany Society of Gynecology and Obstetrics, the guideline has also been approved by the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). This is a guideline published and coordinated by the DGGG. The aim is to provide evidence-based recommendations obtained by evaluating the relevant literature for the diagnostic, conservative and surgical treatment of women with female pelvic organ prolapse with or without stress incontinence. Methods: We conducted a systematic review together with a synthesis of data and meta-analyses, where feasible. MEDLINE, Embase, Cinahl, Pedro and the Cochrane Register were searched for relevant articles. Reference lists were hand-searched, as were the abstracts of the Annual Meetings of the International Continence Society and the International Urogynecological Association. We included only abstracts of randomized controlled trials that were presented and discussed in podium sessions. We assessed original data on surgical procedures published since 2008 with a minimum follow-up time of at least 12 months. If the studies included descriptions of perioperative complications, this minimum follow-up period did not apply. Recommendations: The guideline encompasses recommendations for the diagnosis and treatment of female pelvic organ prolapse. Recommendations for anterior, posterior and apical pelvic organ prolapse with or without concomitant stress urinary incontinence, uterine preservation options, and the pros and cons of mesh placements during surgery for pelvic organ prolapse are presented. The recommendations are based on an extensive and systematic review and evaluation of the current literature and include the experiences and specific conditions in Germany, Austria and Switzerland.

Assessment of pelvic floor muscle contraction with palpation, perineometry and transperineal ultrasound: a cross-sectional study

OBJECTIVE

To study the correlation between palpation, perineometry and transperineal ultrasound for assessment of pelvic floor muscle contraction and to define a contraction scale for ultrasound measurements.

METHODS

This was a cross-sectional study of 608 women examined with palpation of pelvic floor muscle contraction, using the Modified Oxford Scale, and measurement of the vaginal squeeze pressure with a vaginal balloon connected to a fiber-optic microtip transducer (perineometry). Transperineal ultrasound was used for measurements of levator hiatal area and anteroposterior (AP) diameter in the plane of minimal hiatal dimensions, at rest and on contraction. The pelvic floor muscle contraction was expressed as the percentage difference between values at rest and on contraction. Spearman's rank was used to test for correlation between the different methods of assessment.

RESULTS

Significant correlations were found between all assessment methods (P < 0.001). Palpation correlated with perineometry (rs = 0.74) and with proportional change in hiatal area (rs = 0.67) and AP diameter (rs = 0.69) on ultrasound. Perineometry correlated with proportional change in hiatal area (rs = 0.60) and AP diameter (rs = 0.66) on ultrasound. We defined a contraction scale based on the proportional change in AP diameter. In this population, a change in AP diameter of < 7% corresponded to absence of contractions, 7-18% corresponded to weak contractions, 18-35% corresponded to normal contractions and > 35% corresponded to strong contractions.

CONCLUSIONS

We found moderate to strong correlation between ultrasound measurements, palpation and perineometry for assessing pelvic floor muscle contraction. The proportional change in levator hiatal AP diameter was the ultrasound measurement with strongest correlation to palpation and perineometry and formed the basis for the contraction scale for ultrasound measurements.

Validity of Estimation of Pelvic Floor Muscle Activity from Transperineal Ultrasound Imaging in Men

PURPOSE

To investigate the relationship between displacement of pelvic floor landmarks observed with transperineal ultrasound imaging and electromyography of the muscles hypothesised to cause the displacements.

MATERIALS AND METHODS

Three healthy men participated in this study, which included ultrasound imaging of the mid-urethra, urethra-vesical junction, ano-rectal junction and bulb of the penis. Fine-wire electromyography electrodes were inserted into the puborectalis and bulbocavernosus muscles and a transurethral catheter electrode recorded striated urethral sphincter electromyography. A nasogastric sensor recorded intra-abdominal pressure. Tasks included submaximal and maximal voluntary contractions, and Valsalva. The relationship between each of the parameters measured from ultrasound images and electromyography or intra-abdominal pressure amplitudes was described with nonlinear regression.

RESULTS

Strong, non-linear relationships were calculated for each predicted landmark/muscle pair for submaximal contractions (R2-0.87-0.95). The relationships between mid-urethral displacement and striated urethral sphincter electromyography, and bulb of the penis displacement and bulbocavernosus electromyography were strong during maximal contractions (R2-0.74-0.88). Increased intra-abdominal pressure prevented shortening of puborectalis, which resulted in weak relationships between electromyography and anorectal and urethravesical junction displacement during all tasks.

CONCLUSIONS

Displacement of landmarks in transperineal ultrasound imaging provides meaningful measures of activation of individual pelvic floor muscles in men during voluntary contractions. This method may aid assessment of muscle function or feedback for training.

Exploring Occupational Therapists' Perceptions of the Usefulness of Musculoskeletal Sonography in Upper-Extremity Rehabilitation

OBJECTIVE

To identify the potential utility of musculoskeletal sonographic imaging in upper-extremity rehabilitation.

METHOD

Two occupational therapists in an outpatient hand rehabilitation clinic were recruited by convenience, were trained in the use of sonography, and implemented sonographic imaging in their clinical practice. Qualitative data were obtained during and after the implementation period by means of questionnaires and interviews. Data collection, analysis, and interpretation were completed in an iterative process that culminated in a thematic analysis of the therapists' perceptions.

RESULTS

The data indicate four potential areas of utility for musculoskeletal sonography in upper-extremity rehabilitation: (1) mastering anatomy and pathology, (2) augmenting clinical reasoning, (3) supplementing intervention, and (4) building evidence.

CONCLUSION

Numerous potential uses were identified that would benefit both therapist and client. Further exploration of complexities and efficacy for increasing patient outcomes is recommended to determine best practices for the use of musculoskeletal sonography in upper-extremity rehabilitation.

Role of sonographic imaging in occupational therapy practice

Occupational therapy practice is grounded in the delivery of occupation-centered, patient-driven treatments that engage clients in the process of doing to improve health. As emerging technologies, such as medical imaging, find their way into rehabilitation practice, it is imperative that occupational therapy practitioners assess whether and how these tools can be incorporated into treatment regimens that are dually responsive to the medical model of health care and to the profession's foundation in occupation. Most medical imaging modalities have a discrete place in occupation-based intervention as outcome measures or for patient education; however, sonographic imaging has the potential to blend multiple occupational therapy practice forms to document treatment outcomes, inform clinical reasoning, and facilitate improved functional performance when used as an accessory tool in direct intervention. Use of medical imaging is discussed as it relates to occupational foundations and the professional role within the context of providing efficient, effective patient-centered rehabilitative care.
