The objectives of this study were to examine the effects of voluntary sub-maximal activation of the pelvic floor muscles (PFMs) during singing on PFM strength and compliance with the exercise regime. The participants in this pilot interventional study were a convenience sample of 11 asymptomatic (eight at follow-up) and seven symptomatic (five at follow-up) individuals. The primary outcome meas...

There is no consensus on the amount of exercise necessary to improve pelvic floor muscle (PFM) function. We reviewed the pathophysiology of PFM dysfunction and the evolution of PFM training regimens since Kegel introduced the concept of pelvic floor awareness and the benefits of strength. This paper also describes the similarities and differences between PFM and other muscular groups, reviews t...

A novel approach for nanoscale imaging and characterization of the orientation dependence of electromechanical properties-vector piezoresponse force microscopy (Vector PFM)-is described. The relationship between local electromechanical response, polarization, piezoelectric constants, and crystallographic orientation is analyzed in detail. The image formation mechanism in vector PFM is discussed...

[Purpose] The purpose of this study is to verify whether precise contraction of the pelvic floor muscle (PFM) using visual feedback actually affects the thickness of abdominal muscles. [Subjects] The subjects were 29 healthy adults in their 20s who consented to participate in this study. [Methods] This study provided visual feedback on PFM using one ultrasound device and identified changes in t...

[Purpose] The purpose of this study was to analyze the pelvic floor muscle (PFM) activity after vaginal birth, and the effect of parity on PFM strength and quality of life (QoL) in women with urinary incontinence. [Subjects and Methods] Patients (n=241) who gave birth vaginally and experienced urinary incontinence were divided into three groups: group 1 consisted of women having 1-3 children, g...

Introduction: Since the last few decades, the government of Ethiopia has introduced and adopted participatory forest management (PFM) in different regions of the country. However, there is a lack of research dealing with perceptions and attitudes of local people towards PFM in Wof-Washa Forests (WWF). The aim of this study was to evaluate the perceptions and attitudes of local people towards PF...

We describe the partial purification and characterization of a pore-forming material (PEM) from Entamoeba histolytica. The formation of ion channels by PFM was examined in three systems. (a) PFM depolarizes J774 macrophages and mouse spleen lymphocytes as measured by [3H]TPP+ uptake. (b) PFM induces rapid monovalent cation flux across the membrane of phosphatidylcholine-cholesterol vesicles. (c...

Abstract When used as trapped field magnets (TFMs), single grain, bulk high-temperature superconducting (HTS) rings are promising candidates for the generation of strong, uniform magnetic fields nuclear resonance. The pulsed magnetisation (PFM) technique provides a low cost, compact and portable method to magnetise these samples TFMs; however it has proven difficult achieve high in HTS using PF...

This study was a randomized controlled trial to investigate the effect of treating women with stress or mixed urinary incontinence (SUI or MUI) by diaphragmatic, deep abdominal and pelvic floor muscle (PFM) retraining. Seventy women were randomly allocated to the training (n = 35) or control group (n = 35). Women in the training group received 8 individual clinical visits and followed a specifi...
