This article describes investigations of dynamic biomechanical stresses associated with
lifting in stooping and kneeling postures. Twelve subjects volunteered to participate in two …

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 …

Musculoskeletal models may enhance our understanding of the dynamic loading of the
joints during manual material handling. This study used state-of-the-art musculoskeletal …

Large spinal compressive force combined with axial torsional shear force during asymmetric
lifting tasks is highly associated with lower back injury (LBI). The aim of this study was to …

Objective: This study investigated the effects of task precision demands on behavioral and
physiological changes during repetitive asymmetric lifting. Background: Repetitive lifting …

The aim of this study was to assess the effect of an elastic lumbar back support on spinal
loading and trunk, hip and knee kinematics while allowing subjects to move their feet during …

A laboratory study was conducted to assess the effects of lift angle on biomechanical
stresses to the musculoskeletal system, and in particular, on the lower back. Male subjects …

Study Design. In vivo measurements and model studies are combined to investigate the role
of lumbar posture in static lifting tasks. Objectives. Identification of the role of changes in the …

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: Asymmetric lifting activities are associated with low back pain. METHODS:
A finite element biomechanical model is used to estimate spinal loads during one-and two …
