Study Design. Fiber angles of longissimus thoracis and iliocostalis lumborum at L3 were
documented in vivo, using high resolution ultrasound, with the lumbar spine in neutral curve …

A previous modelling study predicted that the forces applied by the extensor muscles to
stabilise the lumbar spine would be greater in spines that have a larger sagittal curvature …

Background: The strength of abdominal muscle and back extensors or their balances are
commonly mentioned as major indicators of potential low back pain (LBP). Former studies …

BACKGROUND CONTEXT: Accurate anatomical inputs for biomechanical models are
necessary for valid estimates of internal loading. The magnitude of the moment arm of the …

This study focused on the electromyographic activity of the trunk musculature, given the well‐
documented link between occupational twisting and the increased incidence of low back …

Abstract Study Design: The superficial and deep lamina of the posterior layer of the
thoracolumbar fascia have been studied anatomically and biomechanically. In embalmed …

Study Design. A comparative study of trunk and hip extensor muscle recruitment patterns in
2 subject groups. Objective. To examine for changes in recruitment of the hip and back …

Background Low back pain (LBP) is an increasingly common condition worldwide with
significant costs associated with its management. Identification of musculoskeletal risk …

The purpose of this study was to develop and evaluate a biomechanical model of lumbar
back extension over a wide range of positions for the lumbar spine, incorporating the latest …

The importance of functional parameters for evaluating the severity of low back pain is
gaining clinical recognition, with evidence suggesting that the angular velocity of lordosis is …
