AIM To assess the role of three-dimensional endoanal ultrasound (3D-EAUS) for morphological assessment of the anal sphincter of female patients with chronic proctalgia (CP). METHODS In this unmatched case control study, 30 consecutive female patients with CP and 25 normal women (control group) were enrolled. 3D-EAUS was performed in all subjects. Thickness and length of internal anal sphincte...

BACKGROUND The purpose of the present study is to establish the relationship and degree of contribution between torque and sonomiography variables (pennation angle - muscle thickness), and electromyography variables (EMGAreaUnderCurve - EMGMaximalPeak) of the tibialis anterior muscle during (TA) maximal and relative isometric foot dorsiflexion (IFD). Secondary aim: To determine the measurement'...

This work aimed at presenting the idea of inventor Dr. Kenzo Kase that kinesio tape application with proximal base leads to muscle contraction facilitation and application with distal base leads to muscle contraction inhibition. Twenty male volleyball players with the dominant shoulder girdle muscle imbalance between the ages of 25 and 30 participated in this study. There were compared two tech...

OBJECTIVES The purpose of the study was to establish regression equations that could be used to predict muscle thickness and pennation angle at different intensities from electromyography (EMG) based measures of muscle activation during isometric contractions. DESIGN Cross-sectional study. METHODS Simultaneous ultrasonography and EMG were used to measure pennation angle, muscle thickness an...

The Achilles tendon and epimuscular connective tissues mechanically link the triceps surae muscles. These pathways may cause joint moments exerted by each muscle individually not to sum linearly, both in magnitude and direction. The aims were (i) to assess effects of sagittal plane ankle angle (varied between 150° and 70°) on isometric ankle moments, in both magnitude and direction, exerted by ...

BACKGROUND During a stretch- shortening cycle (SSC), muscle force attained during concentric contractions (shortening phase) is potentiated by the preceding eccentric contractions (lengthening phase). The purpose of this study was to examine the influence of joint angular velocity on force potentiation induced by SSC (SSC effect). FINDINGS Twelve healthy men (age, 24.2 ± 3.2 years; height, 1....

in this paper we discuss on the fixed points of asymptotic contractions and boyd-wong type contractions in uniform spaces equipped with an e-distance. a new version ofkirk's fixed point theorem is given for asymptotic contractions and boyd-wong type contractions is investigated in uniform spaces.

UNLABELLED The impaired performance of the muscles of the scapular region may result in injuries, fatigue, weakness and pain. The main objective of this research was to analyze the scapular positioning during the abduction of the shoulder movement in the frontal, scapular and sagittal plans. METHOD This cross-sectional study comprised a convenience sample of 20 individuals. It was used the di...
