Study Design A combined finite element and optimization approach was developed to
investigate the clinically relevant biomechanical parameters of the muscular lumbar spine …

Objectives. To quantify the variability in lifting motions, trunk moments, and spinal loads
associated with repeated lifting exertions and to identify workplace factors that influence the …

Background: Strategies of lifting, including stance width and techniques have significant
effects on spine loading and stability. Previous studies examined the influence of them on …

Objective Spine kinematics, kinetics, and trunk muscle activities were evaluated during
different stages of a fatigue-induced symmetric lifting task over time. Background Due to …

Objective. To estimate the three-dimensional spinal loads during various lifting and lowering
tasks. Design. The in vivo measurements of the trunk dynamics, moments, and myoelectric …

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 spinal stability and passive–active load partitioning under dynamic squat and stoop lifts
were investigated as the ligamentous stiffness in flexion was altered. Measured in vivo …

Response surface methodology is used to establish robust and user-friendly predictive
equations that relate responses of a complex detailed trunk finite element biomechanical …

BACKGROUND: An improved assessment of risk of spinal injury during lifting activities
depends on an accurate estimation of trunk muscle forces, spinal loads and stability margin …

Industrial epidemiological studies have shown that jobs requiring a higher speed of trunk
motion contribute to a higher risk of industrial low back disorders. Consideration of the …
