Study Design. An electromyogram-assisted free-dynamic lifting model was used to quantify
the patterns of complex spinal loads in subjects performing various lifting tasks. Objectives …

Background context: Previous research has documented differences in spine loading
between genders when the imposed load is normalized relative to the size of the person …

Background. Physiological and psychophysical studies of the effects of lifting frequency
have focused on whole-body measurements of fatigue or subjective acceptance of the task …

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 …

Most biomechanical assessments of spinal loading during industrial work have focused on
estimating peak spinal compressive forces under static and sagittally symmetric conditions …

Spinal compression is traditionally assumed the principal biomechanical mechanism
associated with occupationally related low-back disorders (LBD). However, there is little …

Study Design. In vivo laboratory studies were conducted to investigate the spine loads
imposed on men and women during a series of lifting tasks that varied in the degree of lifting …

The focus of this study was to assess the amount of error present in several approaches that
have been commonly used to estimate the cumulative spinal loading during manual …

Study Design. Simultaneous trunk kinematic variables of industrial workers performing jobs
with varying degrees of low back disorder risk were quantified, by using a three-dimensional …

Study Design. A repeated-measures in vivo experiment. Objective. To describe within-
subject variability of spinal compression in repetitive lifting. Summary of Background Data …
