Abdominal exercises affect inter-rectus distance in postpartum women: a two-dimensional ultrasound study
(Journal article; Peer reviewed, 2015-09)Objectives: To compare inter-rectus distance (IRD) at rest between women who had a vaginal delivery with women who had a caesarean section, and to describe the effect of different abdominal exercises on IRD. Settin ... -
Altered Triceps Surae Muscle-Tendon Unit Properties after 6 Months of Static Stretching
(Peer reviewed; Journal article, 2021)Introduction: This study examined the effects of 24 wk of daily static stretching of the plantarflexors (unilateral 4 × 60-s stretching, whereas the contralateral leg served as a control; n = 26) on joint range of motion ... -
Automated Characterization of Muscle Architectural Variation in Ultrasound Images
(Peer reviewed; Journal article, 2020)Fascicle (fiber bundle) orientation and length are useful parameters to infer the force potential of skeletal muscles. Ultrasound imaging is commonly used to determine fascicle characteristics. In most of the literature, ... -
Can the Paula method facilitate co-contraction of the pelvic floor muscles?: a 4D ultrasound study
(Journal article; Peer reviewed, 2010-11-23)Introduction and hypothesis: The aim was to compare constriction of the levator hiatus (LH) and reduction of pelvic floor muscle (PFM) length during instruction of the Paula method (contraction of ring musculature of ... -
Comparative analysis of power, work and muscle activation during weight-stack and iso-inertial flywheel resistance exercise in young adults with cerebral palsy
(Peer reviewed; Journal article, 2020)Introduction: The development of efficient resistance exercise protocols to counteract muscle dysfunction in cerebral palsy is warranted. Whether individuals with cerebral palsy are able to perform iso-inertial resistance ... -
Concurrent validity and intrarater reliability of two ultrasound-based methods for assessing patellar tendon stiffness
(Peer reviewed; Journal article, 2022)Introduction: Assessment of tendon stiffness in vivo traditionally involves maximal muscle contractions, which can be challenging in pain populations. Alternative methods are suggested, although the clinimetric properties ... -
Constriction of the levator hiatus during instruction of pelvic floor or transversus abdominis contraction: a 4D ultrasound study
(Peer reviewed; Journal article, 2008-09-20)A new theory claims that the pelvic floor muscles (PFM) can be trained via the transversus abdominis (TrA). The aim of the present study was to compare the effect of instruction of PFM and TrA contraction on constriction ... -
Effects of tracking landmarks and tibial point of resistive force application on the assessment of patellar tendon mechanical properties in vivo
(Journal article; Peer reviewed, 2018)The different methods used to assess patellar tendon elongation in vivo may partly explain the large variation of mechanical properties reported in the literature. The present study investigated the effects of tracking ... -
Imaging-detected acute muscle injuries in athletes participating in the Rio de Janeiro 2016 Summer Olympic Games
(Journal article; Peer reviewed, 2017-12-07)Background: Acute muscle injuries in elite athletes are responsible for a large portion of time loss injuries. Aim: To describe the frequency, the anatomic distribution, and severity of imaging-detected acute muscle injuries ... -
Prevalence and risk factors of diastasis recti abdominis from late pregnancy to 6 months postpartum, and relationship with lumbo-pelvic pain
(Journal article; Peer reviewed, 2014)Diastasis recti abdominis (DRA) is an impairment characterized by a midline separation of the rectus abdominis muscles along the linea alba. It has its onset during pregnancy and the first weeks following childbirth. There ... -
Specific collagen peptides increase adaptions of patellar tendon morphology following 14-weeks of high-load resistance training: A randomized-controlled trial
(Peer reviewed; Journal article, 2023)The purpose of this study was to investigate the effect of a supplementation with specific collagen peptides (SCP) combined with resistance training (RT) on changes in structural properties of the patellar tendon. Furthermore, ... -
Test-retest and intra-observer repeatability of two-, three- and four-dimensional perineal ultrasound of pelvic floor muscle anatomy and function.
(Peer reviewed; Journal article, 2007-06-29)The aims of the present study were to evaluate test–retest intra-observer repeatability of ultrasound measurement of the morphology and function of the pelvic floor muscles (PFMs). Seventeen subjects were tested twice. ... -
Using deep learning to generate synthetic B-mode musculoskeletal ultrasound images
(Peer reviewed; Journal article, 2020)Background and objective Deep learning approaches are common in image processing, but often rely on supervised learning, which requires a large volume of training images, usually accompanied by hand-crafted labels. As ...
