Julie A. Hides ; Clint Frazer ; Peter Blanch ; Brittany Grantham ; Christopher Sexton ; M. Dilani Mendis |Objectives Test the odds of factors previously associated with lower limb injury (decreased size of the multifidus (MF) and increased size of the quadratus lumborum (QL) muscle) in an independent sample of Australian Rules Football (ARF) play[...]Article
Jenna Crook ; Sara Masi ; Neda Naghdi ; Alexa Roussac ; Meaghan Rye ; Brent Rosenstein ; Hassan Rivaz ; Mathieu Boily ; Michael H. Weber ; Maryse Fortin |Purpose The aim of this observational cross-sectional study was to examine correlations of intramuscular fat content in lumbar multifidus (LM) by comparing muscle echo intensity (EI) and percent fat signal fraction (%FSF) generated from ultrasou[...]Article
Objective: To analyze the effects of whole body vibration on electromyographic activity of the core muscles. Methods: This is an observational cross-sectional study composed of 30 males who practice physical activity. The amplitude of the ele[...]Article
Introduction Stretching and strengthening exercises are commonly used to improve muscle shortness. Consequently, the aim of this trial was to compare the flexion-relaxation response (electromyography activities of shortened hamstring and back mu[...]Article
Panakorn Sungnak ; Sranya Songjaroen ; Warin Krityakiarana ; Hsing-Kuo Wang ; Jim Richards ; Peemongkon Wattananon ; Peemongkon Wattananon |Objective To determine lumbar multifidus (LM) muscle activation deficits in individuals with impaired lumbopelvic control (iLPC) based on musculoskeletal ultrasound in conjunction with electrical stimulation approach and the correlation between [...]Travail de fin d'études
Contexte. La lombalgie est le trouble musculosquelettique le plus répandu dans le monde et est la principale cause d’invalidité. Dans 90% des cas, la lombalgie est dite non-spécifique car aucune cause organique n’a été observée. Le rôle de la mo[...]Article
Naoto Matsunaga ; Naoto Matsunaga ; Yu Okubo ; Shunto Isagawa ; Jyunpei Niitsuma ; Takahiro Otsudo ; Yutaka Sawada ; Kiyokazu Akasaka |Introduction Hamstring strain often occurs at the end of a match or during practice in sports activities. The gluteus maximus muscle is an important muscle for hip extension along with the hamstring. Gluteus maximus muscle dysfunction may be inv[...]Article
Morteza Taghipour ; Mohammad Ali Mohseni-Bandpei ; Iraj Abdollahi ; Fatemeh Rajabzadeh ; Neda Naghdi ; Mohammad Reza Pourahmadi |Objectives To evaluate Ultrasound Imaging (USI) reliability for measurement of lumbar multifidus (LMF) muscle thickness and cross sectional area (CSA) at rest and during contraction in patients with unilateral lumbar disc herniation. Setting [...]Article
Soheila Abbasi ; Mohammad-Reza Hadian Rasanani ; Gholamreza Olyaei ; Nastaran Ghotbi ; Omid Rasouli |Objectives Ultrasound (US) imaging has been suggested to evaluate the morphology and function of trunk muscles; however, little is known about the reliability of the US measures in patients with chronic low back pain (CLBP). This study aimed to[...]Article
Daniela Faustino ; Adriane Vieira ; Cláudia Tarragô Candotti ; Emanuelle Francine Detogni Schmit ; Morgana Franciele Rios Xavier ; Victória Alcantara Lunelli ; Jefferson Fagundes Loss |Introduction Although the pressure biofeedback unit (PBU) is used for muscular assessment and training, there is little evidence of its reproducibility and repeatability. Objective This study aims to assess intra- and inter-rater reproducibility[...]Article
Introduction Growing interest is being paid to the lumbar multifidus (LM) intramuscular fatty infiltrations and fibrosis that are secondary to low back pain as well to the remodeling of perimuscular connective tissues (fasciae) such as the thora[...]Article
Robert Vining ; Stephen M. Onifer ; Elissa Twist ; Anna-Marie Ziegler ; Lance Corber ; Cynthia R. Long |Background Differential movement, or shear strain (SS), between layers of thoracolumbar fascia is reduced with chronic low back pain. To provide a foundation for clinical research involving SS, this study assessed temporal stability and the effe[...]Article
Jaclyn Megan Sions ; Emma H. Beisheim ; Mark A. Hoggarth ; James M. Elliott ; Gregory E. Hicks ; Ryan T. Pohlig ; Mayank Seth |Objective The primary purpose of this study was to compare trunk muscle characteristics between adults with and without unilateral lower limb amputation (LLA) to determine the presence of modifiable trunk muscle deficits (ie, impaired activit[...]Article
