Huang L, Zhang ZY, Liu H, Gao M, Wang XQ, Duan XQ, Liu ZL. Most of the pelvic floor muscle functions in women differ in different body positions, yet others remain similar: systematic review with meta-analysis. Front Med (Lausanne) 2023; 10:1252779. [PMID: 38020153 PMCID: PMC10662015 DOI: 10.3389/fmed.2023.1252779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 10/23/2023] [Indexed: 12/01/2023] Open
Abstract
Objectives This systematic literature review and meta-analysis aimed to determine the effect of body position on the measurement of pelvic floor muscle (PFM) contractility and to analyze the influential factors. Data sources Five databases (PubMed, Web of Science, EMBASE, Cochrane Library and Scopus) were searched for relevant studies published up to 12nd October 2023. Study selection or eligibility criteria Included cross-sectional studies had to involve the assessment of pelvic floor muscle function in at least two positions. Study appraisal and synthesis methods We calculated standardized mean difference (SMD) with 95% confidence intervals (CI) to ascertain the potential effect of body position on outcomes. Results In total, we included 11 cross-sectional studies to ascertain the potential effect of body position on outcomes. There was no statistical difference in the results of maximum voluntary contraction (MVC) of the pelvic floor muscles when assessed in between supine and standing positions (SMD -0.22; 95% CI -0.72 to 0.28; p = 0.38). The results of the meta-analysis showed significantly larger values of resting voluntary contractions (RVC) measured in the standing position compared to the supine position (SMD -1.76; 95% CI -2.55 to -0.97; p < 0.001). Moreover, pelvic floor muscle movement during pelvic floor muscle contraction in the standing position was significantly better than that measured in the supine position (SMD -0.47; 95% CI -0.73 to 0.20; P < 0.001). Conclusion The results of this study showed that the RVC and PFM movement varied with the position of the assessment. In contrast, MVC values are independent of the assessment position and can be selected according to clinical needs.

The effect of biofeedback pelvic floor training with ACTICORE1 on urinary incontinence: a multicenter randomized clinical pilot trial. Ann Med Surg (Lond) 2023; 85:4860-4865. [PMID: 37811051 PMCID: PMC10553154 DOI: 10.1097/ms9.0000000000001181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 08/04/2023] [Indexed: 10/10/2023] Open
Abstract
Background Pelvic floor training with biofeedback has been shown to significantly reduce symptoms of urinary incontinence. The present study aimed to evaluate the effectiveness of pelvic floor training with the ACTICORE1 biofeedback device, which uses a noninsertable pelvic floor sensor with a digital interface. Materials and methods A multicenter randomized controlled clinical pilot study in Germany was conducted between October 2021 and January 2022. The intervention group was instructed to use ACTICORE1 for 6 min daily to train the pelvic floor for 12 weeks. The control group was instructed not to do any pelvic floor training. Over 18-year-old men and women with urinary incontinence and an International Consultation on Incontinence Questionnaire score (ICIQ) of ≥5 were included in the study. The primary endpoint was the ICIQ score 12 weeks after enrollment. The secondary endpoints were the ICIQ score and quality of life using the EG-5D-3L questionnaire 4, 8, and 12 weeks after patients' enrollment. Results A total of 40 individuals with urinary incontinence were recruited for the present study (35 females, 5 males; 40% lost to follow-up). In terms of biometric data, both groups did not differ. At 4, 8, and 12 weeks, the ICIQ scores of those in the ACTICORE1 group decreased from 12.9 to 7.5. The ICIQ score in the control group decreased from 11.0 to 10.5. The intraindividual improvement of patients in the ACTICORE group was statistically significant. Conclusion Biofeedback training with ACTICORE1 significantly reduces symptoms of urinary incontinence after 12 weeks.

Abstract
Since the digital revolution, there has been a notable increase in the use and popularity of sex toys and innovative sexual devices, which can be attributed to advancements in technology. The sex toys industry strives to improve sexual experience, pleasure and sexual health, and to address sexual dysfunction through devices and technology. With the growth of this industry, new products that are considered "smart sexual devices" have gradually entered the market. Smart sexual devices feature wireless connectivity to a smartphone application that allows the user to control the device's features and provide personal or sexual data about their sexual experiences. Other smart devices have sensors and are able to collect physical data during usage. With the aid of this data, individuals may be able to understand their sexual behavior and arousal better, resulting in improved sexual experience or the overcoming of sexual dysfunction. The present article aims to explore the potential applications of technology-based devices, and smart sexual devices, in the treatment of male sexual dysfunctions, including premature ejaculation (PE), and delayed ejaculation (DE), as well as female sexual dysfunction (FSD), such as sexual arousal disorder and female orgasmic disorder. Furthermore, we examine the advantages and disadvantages of these devices. Given the limited literature available on this subject and the absence of controlled studies, we conduct a narrative review of the existing scientific research on technological and smart sexual devices.

Abstract
OBJECTIVE The purpose of this technical update is to establish the state of the science regarding emerging and novel electronic health (eHealth) and mobile health (mHealth) solutions for urinary incontinence among women. TARGET POPULATION Women over 18 years with urinary incontinence. OPTIONS Websites and mobile health applications are useful in the conservative care of urinary incontinence. Relevant care providers should be familiar with such tools, particularly those that use motivational principles for behaviour change, which can be used as adjunct tools for urinary incontinence care. Telemedicine is an effect mode to provide services for the conservative care of urinary incontinence. OUTCOMES Use of eHealth and mHealth solutions has potentially significant health outcomes for patients, providers, and global health systems. Broader use of telemedicine, in and of itself, could improve care access and reduce costs incurred by patients and the health care system. BENEFITS, HARMS, AND COSTS Evidence for the efficacy of eHealth and mHealth technologies and applications for urinary incontinence ranges from weak to strong. However, the research landscape for many of these novel solutions is developing rapidly. Furthermore, these options have minimal or no harm and confer an established cost benefit and care access benefit. EVIDENCE The Cochrane Library, Medline, EMBASE, CENTRAL databases (from January 2014 to April 2019) were searched to find articles related to conservative care of urinary incontinence in women (over 18 years) and studies on eHealth and mHealth interventions for urinary incontinence. Articles were appraised, and the collective evidence was graded. 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 Relevant primary care providers and medical specialists, including physicians, nurses, midwives, and pelvic health physiotherapists. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
AIMS To discuss the advantages and limitation of the different pelvic floor muscle (PFM) dynamometers available, both in research and industry, and to present the extent of variation between them in terms of structure, functioning, psychometric properties, and assessment procedures. METHODS We identified relevant studies from four databases (MEDLINE, Compendex, Web of Science, and Derwent Innovations Index) up to December 2020 using terms related to dynamometry and PFM. In addition, we conducted a hand search of the bibliographies of all relevant reports. Peer-reviewed papers, conference proceedings, patents and user's manuals for commercial dynamometers were included and assessed by two independent reviewers. RESULTS One hundred and one records were included and 23 PFM dynamometers from 15 research groups were identified. From these, 20 were considered as clinical dynamometers (meant for research settings) and three as personal dynamometers (developed by the industry). Overall, significant heterogeneity was found in their structure and functioning, which limits development of normative data for PFM force in women. Further research is needed to assess the psychometric properties of PFM dynamometers and to standardize assessment procedures. CONCLUSION This review points up to the heterogeneity of existing dynamometers and methods of assessing PFM function. It highlights the need to better document their design and assessment protocol methods. Additionally, this review recommends standards for new dynamometers to allow the establishment of normalized data.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize and assess the current non-surgical devices for the treatment of stress urinary incontinence (SUI). RECENT FINDINGS Devices for SUI can generally be divided into two categories. One category is the augmentation of pelvic floor muscle training (PFMT), wherein devices such as vaginal cones, intravaginal biofeedback, and electrical or magnetic stimulation are used to strength the pelvic floor musculature, though none are more effective than traditional PFMT. The second category of devices mechanically occludes the outlet and includes incontinence pessaries, intravaginal occlusion devices, and urethral plugs and patches. While these are palliative rather than curative, they share similar rates of improvement in leakage. A number of novel devices exist for the treatment and management of SUI. Though no single device has been shown to be more effective than PFMT alone, they may be beneficial for women who have difficulty isolating their pelvic floor muscles, desire accountability, or prefer technology-based engagement. Outlet occlusion devices are less comfortable for the patient, but remain an option for women who do not desire surgery.

What improvements in levator ani motor function lead to improvement in stress urinary incontinence signs and symptoms in females? Int Urogynecol J 2021; 33:2735-2747. [PMID: 34477898 DOI: 10.1007/s00192-021-04931-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Accepted: 06/25/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION AND HYPOTHESIS The objectives were to determine whether levator ani muscle (LAM) motor function is associated with female stress urinary incontinence (SUI) severity, and whether changes in LAM motor function induced through pelvic floor muscle training (PFMT) are associated with improvements in SUI signs and symptoms. METHODS Pelvic morphology and LAM function were evaluated using ultrasound imaging and manual palpation using the elements of the PERFECT Scheme (Power, Endurance, Repetitions, Fast contractions, Elevation, Co-contraction and Timing) before and after women with SUI underwent a 12-week PFMT intervention. SUI severity was determined subjectively (ICIQ-FLUTS-UI) and objectively (30-min pad test [30MPT]). RESULTS At baseline (n = 97), less leakage on the 30MPT was weakly associated with higher bladder neck position (ρs = -0.209,p = 0.044), yet with lower LAM function based on the PERFECT Scheme (overall score: ρs = 0.206, p = 0.043; repeated maximum voluntary contractions (MVCs): ρs = 0.203, p = 0.046; power/motor control: ρs = 0.214, p = 0.035). Lower symptom severity (ICIQ-FLUTS-UI) was associated with observed perineal lift during coughing (U = 34.000; p = 0.042). All measures of SUI severity and LAM function were significantly improved after PFMT intervention. Greater improvements in bladder neck elevation during MVC (ρs = -0.261, p = 0.027) and greater reductions in levator plate length during MVC (ρs = 0.292, p = 0.016) were weakly associated with greater reductions in leakage (30MPT), the latter also being associated with more improvement symptoms (ICIQ-FLUTS-UI; ρs = 0.238, p = 0.041). Greater improvement in the ability to repeat MVCs (ρs = 0.303, p = 0.009) was weakly associated with smaller improvements in symptoms (ICIQ-FLUTS-UI). CONCLUSION Improvements in bladder neck support and elevation show weak associations with improvement in SUI signs and symptoms. LAM function as measured by the PERFECT Scheme is not associated with SUI severity in women, and improvements in LAM function when measured by the PERFECT Scheme are not associated with improvements in SUI signs and symptoms.

Abstract
AIMS (1) To present the design of a novel intravaginal dynamometer (IVD) capable of measuring vaginal closure force on both the anterior and posterior arms, (2) to use bench testing to validate the force, speed of arm opening, and positional accuracy of load measurement along the IVD arms, and (3) to present in vivo force measurements made with this device, comparing forces measured by the anterior and posterior arms. METHODS IVD load measurements were validated against an Instron® Universal Tester, arm opening speeds were validated using video analysis, and position-load accuracy was validated against calibration weights. In vivo IVD data were acquired from female volunteers during passive opening and pelvic floor muscle contraction tasks. Anterior and posterior IVD arm force outcomes were compared. RESULTS Forces measured by the IVD and Instron® exhibited a strong linear relationship with excellent model fit. The speed control system was valid when tested under physiological loading conditions, however smaller antero-posterior opening diameters (25 and 30 mm) exhibited some error. The loading position along the IVD arms had no effect on force outcomes. In vivo data exhibited differences between force outcomes measured at the anterior and posterior aspects of the vagina during active contraction and passive elongation of the pelvic floor muscles. CONCLUSIONS This IVD design demonstrates valid load measurement and speed control during bench testing. Active and passive forces measured are consistent with the literature. With dual instrumented arms, this device allows for further investigation into the source of measured vaginal closure forces.
