Flexion–extension moments acting at the L5/S1 level and hip joints were calculated using
three different techniques; a pure static analysis, a static analysis including the inertial force …

Flexion-extension moments occurring at the L5-S1 level of the spine were calculated when
subjects lifted a 150N box at slow, normal and fast speeds. Three methods of lifting were …

Flexion-extension moments occurring at the L5-S1 level of the spine were calculated when
subjects lifted a box weighing from 50 to 250 N. Lifting was performed at normal and fast …

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

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 …

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 …

Low back loading during occupational lifting is thought to be an important causative factor in
the development of low back pain. In order to regulate spinal loading in the workplace, it is …

Assessment of the effects of lifting on the low back has most frequently been done with the
aid of static models. Many lifting movements appear to have substantial inertial components …

The mechanical loading on the body during the act of lifting has been estimated frequently.
The opposite act of lowering has received much less attention. The aim of the present study …

A study was performed to determine the influence of load magnitude on the self selected
technique of lifting. Specifically, it was hypothesized that with heavier weights a tendency …
