Impact of pelvic floor muscle strength on female sexual function: retrospective multicentric cross-sectional study.

INTRODUCTION AND HYPOTHESIS: The female pelvic floor muscles (PFM) play an important role in sexual function. We hypothesize that there is a relation between PFM strength and sexual function in women with and without sexual dysfunction. METHODS: Retrospective multicentric cross-sectional study including women with and without sexual dysfunction [Female Sexual Function Index (FSFI) cutoff point < 26.55], analyzed by age range, considering demographic, clinical, anthropometric and PFM strength [Modified Oxford Scale (MOS)] data. Chi-square, Mann-Whitney test and linear regression (ranks) were used, with 5% significance (SAS 9.4). RESULTS: Out of 1013 medical records, 982 women with an average age of 45.76 (± 15.25) were included in the study. Of these, 679 (69.14%) presented FSFI score < 26.55, while 303 (30.86%) presented FSFI ≥ 26.55. It was identified that the higher scores were among white women, < 45 years old, single, with higher education, family income > 4 minimum wages, body mass index < 25 kg/m2, lower parity, regular physical activity practitioner and higher PFM strength (MOS: 4-5). Desire, arousal, lubrication and orgasm domains were higher among women with MOS 4-5, while satisfaction and pain domains were higher among those with MOS 3-5. CONCLUSION: Demographic, clinical and anthropometric conditions can influence both PFM strength and female sexual function. Our findings demonstrate that women with higher PFM strength present fewer complaints about sexual dysfunction.

Electromyographic analysis of maximal voluntary contraction of female pelvic floor muscles: Intrarater and interrater reliability study.

AIMS: To investigate the intrarater and interrater reliability of the surface electromyography (sEMG) of female pelvic floor muscles (PFM) by visual determination of the onset-offset during maximal voluntary contraction (MVC). METHODS: Intrarater and interrater reliability study. Three MVC, recorded for 5 s (s) each and separated by intervals of 60 s, were requested. Two independent raters visually determined the onset and offset of each MVC. The agreement between raters on the quality of the signals was analyzed both qualitatively (visual inspection) and quantitatively (signal-to-noise ratio, SNR). The reliability of integral and median frequency (MDF) of sEMG signals during MVC was analyzed using intraclass correlation coefficient (ICC) models (ICC2,1 , ICC2,3 ) and repeated measures analysis of variance. RESULTS: A total of 58 women (mean age of 54 years) and two independent raters participated in the analyses. Of the total, 22 (37.9%) were considered of high quality by both raters and the SNR ranged 34.3-22.2 decibels (dB). The agreement of qualitative visual evaluation of the sEMG signal was fair (Cohen's κ = 0.306 [0.148; 0.463]). Intrarater and interrater reliability were excellent for the average of the three MVC, both for integral (ICC2,3 = 0.884 [0.821; 0.925]; ω2 = -0.006, p = 0.558) and MDF (ICC2,3 = 0.998 [0.998; 0.999]; ω2 = -0.009, p = 0.992). CONCLUSION: Qualitative visual analysis of the sEMG signal presents fair interrater agreement and reflects the SNR. Visual determination of the onset and offset of the MVC of PFM using the standard interface of the sEMG software has excellent reliability for determination of muscle activation variables.

The Brazilian version of the Health-Related Quality of Life Questionnaire for Nausea and Vomiting of Pregnancy: translation, cross-cultural adaptation and reliability - an observational cross-sectional study.

BACKGROUND: The Health-Related Quality of Life Questionnaire for Nausea and Vomiting of Pregnancy (NVPQOL) is a validated questionnaire assessing quality of life among pregnant women with nausea and vomiting. OBJECTIVE: To translate, cross-culturally adapt and evaluate the reliability of the NVPQOL. DESIGN AND SETTING: Observational cross-sectional study developed in a public university in Brazil. METHODS: The translation, synthesis of translations, back-translation, expert committee, pre-testing and validation were carried out, resulting in a Portuguese-language version. The internal consistency, intra-rater and test-retest reliability and correlation between the total score of the Portuguese-language version of the NVPQOL and the domains of the World Health Organization Quality of Life-bref questionnaire were considered in the data analysis. RESULTS: The instrument went through the process with testing on 104 pregnant women. Strong internal consistency (Cronbach's α: 0.95), strong intra-rater and test-retest reliability (P < 0.0; intraclass correlation coefficient: 0.89; confidence interval: 0.791-0.945) and strong correlation between the total score of the Portuguese-language version of the NVPQOL and the physical health domain of the World Health Organization Quality of Life-bref questionnaire (P < 0.01; R = -0.8) were observed. CONCLUSION: The NVPQOL was translated, cross-culturally adapted and validated for the Portuguese language with satisfactory psychometric properties for assessing quality of life, especially in relation to physical health, among pregnant women with symptoms of nausea and vomiting in the first trimester of pregnancy.

Galvano-puncture and dermabrasion for striae distensae: a randomized controlled trial.

OBJECTIVE: To assess the effects of galvano-puncture (GG) and dermabrasion (DG) in reducing striae distensae in the gluteal region of women. METHODS: This randomized, controlled, single-blind clinical trial was conducted at the UNIFAL-MG. Participants were 48 female who had striae distensae alba in the gluteal region. They were randomly divided in GG; DG; and Control Group (CG). The length and width of the largest striae were measured (in millimeters) using a caliper. The same striae were assessed before and after treatment. Infrared thermography was performed in the gluteal region to assess local microcirculation. RESULTS: Intragroup analysis showed a significant reduction in the dimension of the striae between baseline and treatment session 10 in the GG and DG groups. Between-group analysis revealed a reduction in the width and length of the striae for both the GG and DG groups, but there were no significant differences between the two groups. When compared to the CG and the DG group, the GG group had significant improvements, as shown by thermography. CONCLUSION: Both GG and DG are effective in reducing striae length and width. However, only the thermography results showed significant differences between GG and control, and between GG and DG.
