Chronic pelvic pain (CPP) is a highly disabling disorder in women usually associated with hypertonic dysfunction of the pelvic floor musculature (PFM). The literature on the subject is not conclusive about the diagnostic potential of surface electromyography (sEMG), which could be due to poor signal characterization. In this study, we characterized the PFM activity of three groups of 24 subjects each: CPP patients with deep dyspareunia associated with a myofascial syndrome (CPP group), healthy women over 35 and/or parous (>35/P group, i.e., CPP counterparts) and under 35 and nulliparous (<35&NP). sEMG signals of the right and left PFM were recorded during contractions and relaxations. The signals were characterized by their root mean square (RMS), median frequency (MDF), Dimitrov index (DI), sample entropy (SampEn), and cross-correlation (CC). The PFM activity showed a higher power (>RMS), a predominance of low-frequency components (<MDF, >DI), greater complexity (>SampEn) and lower synchronization on the same side (<CC) in CPP patients, with more significant differences in the >35/P group. The same trend in differences was found between healthy women (<35&NP vs. >35/P) associated with aging and parity. These results show that sEMG can reveal alterations in PFM electrophysiology and provide clinicians with objective information for CPP diagnosis.

Introduction The pelvic floor is made of a mutually connected system that consists of muscles, connecting tissue and nerve components. Damage to any of these elements creates dysfunction which is exerted through stress, urinary incontinence, prolapse of genital organs and faecal incontinence. Objective The primary aim of this study was to present the possibility of objective assessment of pelvic floor muscle force in healthy and sick women using a newly designed instrument, the vaginal dynamometer, as well as to establish the correlation between the values of pelvic floor muscle force obtained by the vaginal dynamometer and digital palpation method. Methods The study included 90 female patients, age 20-58 years. One group of respondents was made of healthy women (who gave birth, and those who have not given birth), while the other one consisted of sick women (who suffered from incontinence or prolapse of genital organs, operated on or not). The pelvic floor muscle strength of every woman was measured with a newly-constructed device for measuring and monitoring of the pelvic floor muscle force in women, the vaginal dynamometer. Then it was compared with the valid clinical digital palpation (palpation with two fingers) based on the scale for measuring muscle contractions with the digital palpation - the digital pelvic assessment rating scale. The vaginal dynamometer consists of a redesigned speculum which is inserted into the vagina and a sensor for measuring the force. Results Statistically significant linear correlation was found in the values of the measured muscle force with the vaginal dynamometer and ratings produced by digital palpation (r=0.92; p<0.001). Mean value of the muscle force of the healthy women measured by the vaginal dynamometer was 1.44?0.38 daN and that value of the sick women was 0.78?0.31 daN (t=8.89 for df=88; p<0.001). Mean value of the ratings produced by digital palpation in healthy women was 4.10 (95% of trust limits 3.83- 4.37), while the value in sick women was 2.41 (95% of trust limits 2.10-4.16) (Z=-6.38; p<0.001). Conclusion The vaginal dynamometer has been presented as an attempt to overcome the limitations of the previously presented techniques for muscle force measurement. The application of the vaginal dynamometer in clinical practice makes objective and numerical assessment of pelvic floor muscle force possible, independent of the subjective assessment of the examiner. The usage of this instrument enables not only the diagnostics of women's pelvic floor muscle problem, but also the objective monitoring of rehabilitation gynecological medicine results.

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.
