Reliability and Validity of Pelvic Floor Muscle Strength Assessment Using the MizCure Perineometer

Abstract Background The purpose of this study was to clarify the reliability and validity of pelvic floor muscle (PFM) strength assessment using the MizCure perineometer in healthy women. Methods Twenty healthy women (age 20–45 years) participated in this study. The vaginal pressure measurements using the MizCure and Peritron perineometers were repeated during PFM contraction in the supine and standing positions. All women were evaluated twice by examiners 1 and 2. Following the measurements in the first session (Test 1), they were repeated after an interval of between 2 and 6 weeks (Test 2). Within- and between-session intra- and inter-rater reliabilities in vaginal pressure were analyzed using intraclass correlation coefficients (ICC) (1, 1) and (2, 1), respectively. Validity was assessed by Pearson’s product-moment correlation coefficient and Spearman’s rank correlation analysis. Results Within-session intra-rater reliabilities for both examiners 1 and 2 for all vaginal pressures in Tests 1 and 2 were 0.90 to 0.96 for both perineometers. Between-session intra-rater reliability for the MizCure was 0.72 to 0.79 for both positions for examiner 1, and 0.63 in the supine position and 0.80 in the standing position for examiner 2. Inter-rater reliability for Test 1 was 0.91 in the supine position and 0.87 in the standing position for the MizCure. The vaginal pressures using the MizCure and Peritron were significantly associated with the supine position (r = 0.68, P < .001) and the standing position (rs = 0.82, P < .001). Conclusion Measurement of PFM strength using the MizCure perineometer is a reliable and valid method in healthy women.

SUMMARYChildbirth is often considered the main etiological factor in the development of female urinary incontinence(UI). For that reason women in the western countries have been encouraged to engage in post partumpelvic floor muscle (PFM) exercise in order to strengthen the pelvic floor. However, the effect of post partumPFM exercise has been sparsely documented. The aim of this article is to review and discuss literaturerelated to prevalence of post partum UI and effect of post partum PFM exercise in the treatment of UI. Thereported prevalence of UI post partum varies from 0.7% to 44%. The variation may be explained bydifferent definitions of UI used in the questionnaires and that the registration of incontinence was done atdifferent intervals after delivery. A few studies have tried to evaluate the effect of post natal PFM exercise.Some have evaluated PFM strength, others the frequency of UI. PFM strength is difficult to measure andthe reliability and validity of the methods used is open to question. Another flaw in some of the previousstudies is the training protocol applied to improve PFM strength. Mørkved and Bø tried to take intoaccount the above mentioned methodological considerations, in a study aiming to evaluate the effect ofpost partum PFM exercise. The results demonstrate that post partum PFM exercise is effective instrengthening the PFM and in the treatment of UI. However, success of PFM exercise is dependent uponboth the training frequency and intensity. This requires a closer follow up of the post partum women, thanthe written information that usually serves this purpose at the present time.Key words : physiotherapy, pelvic floor muscles, urinary incontinence, post partum exercise, prevalence

Abstract Evaluation of pelvic-floor muscle (PFM) function and strength is necessary (1) to be able to teach and give feedback regarding a woman's ability to contract the PFM and (2) to document changes in PFM function and strength throughout intervention. The aims of this article are to give an overview of methods to assess PFM function and strength and to discuss the responsiveness, reliability, and validity of data obtained with the methods available for clinical practice and research today. Palpation, visual observation, electromyography, ultrasound, and magnetic resonance imaging (MRI) measure different aspects of PFM function. Vaginal palpation is standard when assessing the ability to contract the PFM. However, ultrasound and MRI seem to be more objective measurements of the lifting aspect of the PFM. Dynamometers can measure force directly and may yield more valid measurements of PFM strength than pressure transducers. Further research is needed to establish reliability and validity scores for imaging techniques. Imaging techniques may become important clinical tools in future physical therapist practice and research to measure both pathophysiology and impairment of PFM dysfunction.

Footprint Analysis

Background Several sophisticated methods of footprint analysis currently exist. However, it is sometimes useful to apply standard measurement methods of recognized evidence with an easy and quick application. We sought to assess the reliability and validity of a new method of footprint assessment in a healthy population using Photoshop CS5 software (Adobe Systems Inc, San Jose, California). Methods Forty-two footprints, corresponding to 21 healthy individuals (11 men with a mean ± SD age of 20.45 ± 2.16 years and 10 women with a mean ± SD age of 20.00 ± 1.70 years) were analyzed. Footprints were recorded in static bipedal standing position using optical podography and digital photography. Three trials for each participant were performed. The Hernández-Corvo, Chippaux-Smirak, and Staheli indices and the Clarke angle were calculated by manual method and by computerized method using Photoshop CS5 software. Test-retest was used to determine reliability. Validity was obtained by intraclass correlation coefficient (ICC). Results The reliability test for all of the indices showed high values (ICC, 0.98–0.99). Moreover, the validity test clearly showed no difference between techniques (ICC, 0.99–1). Conclusions The reliability and validity of a method to measure, assess, and record the podometric indices using Photoshop CS5 software has been demonstrated. This provides a quick and accurate tool useful for the digital recording of morphostatic foot study parameters and their control.

Abstract Introduction: The obtaining of urinary continence is due to the strength of the pelvic floor muscles (MAPs) at the moment of muscle contraction, when there are sudden increases in intra-abdominal pressure, which increases urethral closure pressure and decreases the possibility of urinary loss. Objective: To verify the reliability, type: stability, intra-examiner, of the measure of the strength of MAPs held with Peritron. Methods: Test and retest study to assess the intra-rater reliability of Peritron to measure the strength of MAPs. The sample consisted of 36 male patients, mean age 65.3 ± 7.2 years, all with urinary incontinence (UI) after radical prostatectomy. The physical therapist conducted a training for familiarization with the procedures of MAPs strength assessment with Peritron for two weeks. The strength of MAPs was measured by a perineometer of the Peritron brand (PFX 9300®, Cardio-Design Pty. Ltd, Baulkham Hills, Australia, 2153). Results: The intraclass correlation coefficient (ICC) was equal to 0.99; P = 0.0001. The typical measurement error (ETM) was equal to 3.1 cmH2O and ETM% of 4. Conclusion: Peritron showed high reliability for measuring the strength of MAPs in men, both for clinical practice and for the production of scientific knowledge. It should be noted that such measures were carried out in stability, so it is suggested that in internal consistency reliability is equivalent.

Objectives: The present systematic review focused on the prevention or treatment of three main types of pelvic floor dysfunctions (PFDs) specifically pelvic organ prolapse (POP), urinary incontinence (UI), and fecal incontinence (FI) using physiotherapy and pelvic floor muscle exercises (PFMEs). With regard to the breadth of the problem, there is not much evidence grounded on the best management. The main purpose of this systematic review was to evaluate the effects of physiotherapy and PFMEs on the prevention and treatment of pregnancy-related PFDs; namely, POP, FI, and UI. Therefore, this review incorporated studies comparing the use of physiotherapy and PFMEs with every other existing interventions. Methods: This systematic review and meta-analysis was conducted on randomized-controlled-trial (RCT) articles and quasi-RCT designs through a search in the studies published with no time limits until December 2017 in the databases of PubMed (Medline), Web of Science, Scopus, Embase, Cochrane Library, and ProQuest. The meta-analysis was also applied for data synthesis. Moreover, heterogeneity was assessed using Cochran’s Q test and I2 index. Results: A total number of 26 RCTs were examined in this review in which the outcome variables were related to POP, UI, and FI prevalence; POP, UI, and FI severity, as well as pelvic floor muscle (PFM) strength and endurance. In most articles, UI prevalence or severity in intervention groups had significantly improved compared with those in controls. The number of studies examining POP and FI was also relatively low. In two studies, FI severity or prevalence in intervention groups had significantly enhanced in comparison with those in control groups; however, FI prevalence in two articles had been reported lower in intervention groups than that in control groups although no significant difference had been observed. There was also no significant improvement in intervention groups in two other studies in this respect. Besides, three articles had not reported traces of improvement in POP, as well as a significant difference between intervention and control groups. Nevertheless, two studies had found a significant improvement in POP in this regard. Based on meta-analysis results for the variable of PFM strength, Cochran’s Q test (P<0.001) and I2 index (90.02) indicated heterogeneity between studies; so, a random-effect meta-analysis was applied to estimate overall effect sizes. The overall mean differences following intervention between the study groups were also equal to 6.94, with a 95% CI (1.36 to 12.52). Conclusions: It was concluded that physiotherapy and PFMEs might have effects on pregnancy-related UI, but they had not consistently reduced FI severity or prevalence and failed to constantly improve POP.

The aim of this study was to evaluate the intra- and inter-examiner reliability and validity of neck range of motion (ROM) measurements. Thirty-five healthy subjects were assessed in all neck movements from two initial positions, sitting and standing, actively (open and closed eyes) and passively by using a 3D ultrasound-based motion analysis device (Zebris). Three tests were employed to assess intra-examiner reliability and two examiners used for the inter-examiner reliability. X-rays in neck flexion and extension were used to validate the Zebris system. The standing position yielded higher intraclass correlation coefficient (ICC) values (>0.86) with less error [smallest detectable difference (SDD) < 13.8%] than sitting (ICC > 0.79, SDD < 14%). Passive assessment of neck ROM presented better reproducibility than active assessment with open or closed eyes in both positions. The inter-examiner reliability was moderate (ICC = 0.43-0.68). The correlation between the Zebris system and X-rays was high in both flexion and extension movements. The results showed that the most reliable protocol for assessment of neck ROM is a passive measurement in the standing position. The measurements were well validiated against X-rays and the experience of the investigators must be considered before any comparison among studies is employed.

AbstractBackground and Purpose. Pelvic-floor muscle (PFM) exercises are effective in reducing stress urinary incontinence (SUI), but few studies have investigated the effect of specific exercise variables on treatment outcomes. This study explored the effect of exercise position on treatment outcomes in women with SUI. Subjects and Methods. Forty-four women were randomly assigned to exercise in the supine position only or in both supine and upright positions. Bladder diary, pad test, urodynamic test, quality-of-life (Incontinence Impact Questionnaire [IIQ]), and PFM strength outcomes were obtained at baseline and after treatment. Results. Exercise position did not affect outcomes. After data from both groups were collapsed, statistically significant improvements with treatment were observed in bladder diary, IIQ, PFM strength, and urodynamic test results. Discussion and Conclusion. Exercise position did not differentially affect treatment outcomes. However, women in this study achieved a mean 67.9% reduction in the frequency of SUI episodes and improvements in other study outcomes. [Borello-France DF, Zyczynski HM, Downey PA, et al.
