Epidemiological studies have shown that loads imposed on the human spine during daily
living play a significant role in the onset of low back pain. The loads applied to the lumbar …

Irrespective of the lifting technique (squat or stoop), the lumbar spine posture (more kyphotic
versus more lordotic) adopted during lifting activities is an important parameter affecting the …

Objective. A three-dimensional dynamic mathematical model was developed to discover
what loads are imposed on the lumbar structures by performance of asymmetric manual …

Cadaveric studies have shown that intervertebral discs and ligaments are most vulnerable to
injury when loaded simultaneously in bending and compression. The purpose of the present …

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 …

A dynamic biomechanical human model is presented which allows the quantification of
mechanical parameters such as torque, compressive and shear forces, and pressure at the …

This experimental study investigated the effects of load magnitude and movement speed on
lumbar vertebral kinematics during lifting task performance. Ten participants performed …

Abstract Evaluation of spinal loads in patients with low back pain (LBP) is essential to
prevent further lumbar disorders. Many studies have investigated the relationship between …

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 …

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 …
