Assessing Low Back Stress in the Construction Industry Using the Continuous Assessment of Back Stress (CABS) Method

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1998
The construction industry has long been identified as a high risk industry for low back injuries due to the significant amount of manual materials handling and awkward trunk postures associated with many of its jobs. The variable nature of the tasks performed by construction workers expose these workers to risk factors for both acute and cumulative ...

Helping children with back‐to‐school stress

The Brown University Child and Adolescent Behavior Letter, 2022
By now, most children have been in classrooms for at least a month. While the return to once‐familiar routines may seem refreshing to parents, the fears of lockdown still haunt children, and these are only compounded by regular stressors caused by school.

Back-stresses, image stresses, and work-hardening

Acta Metallurgica, 1973
Abstract A comparison is made between recently published theories on the plastic behaviour of dispersion-hardened alloys in which no plastic relaxation occurs. It is shown that Tanaka and Mori's(1) calculation is a rigorous lower bound for the hardening to be expected. Some new derivations are given for the mean strains in matrix and inclusions.

Back calculation of in-situ stress condition based on secondary stress measurements

The IV Nordic Symposium on Rock Mechanics and Rock Engineering - Proceedings, 2023
A large underground cavern design at a shallow depth requires reliable estimation of in-situ stress conditions. Geological conditions, topography, and tectonic activity influence the magnitude of the in-situ stresses. The objective of this paper is to predict and evaluate the in-situ stress state before the excavation of two pilot tunnels in a railway ...

Spinal stress—an approach to quantification with respect to back pain

Clinical Biomechanics, 1987
Back pain is a major problem throughout the industrialized world, and although its aetiology is ill understood, the problem demands immediate attention. This paper briefly describes the investigative strategy used in studies of back pain by the Ergonomics Research Unit at the University of Surrey.

Stressing life events and the experience of low back pain

Journal of Psychosomatic Research, 1979
Abstract Life-stress events, attributes of low back pain, anxiety, hostility and depression were measured in 148 patients hospitalized for evaluation and treatment of low back pain. Fifty-seven of these patients had definite organic disease, 51 had probable organic disease, and 40 had no demonstrable organic disease.

Causal Relation of Psychical Stress to Acute Back Pain

Acta chirurgiae orthopaedicae et traumatologiae Cechoslovaca, 2018
PURPOSE OF THE STUDY There s a known relation between the chronical back-pain-syndrome and psychical problems. We suppose a direct causality between acute stress and onset of the backpain syndrome. MATERIAL AND METHODS A prospective cohort-study (IV/2014 - VIII/2014) of patients who came to our emergency department with acute backpain-syndrome, with no

Attributions, Stress, and Work-Related Low Back Pain

Applied Occupational and Environmental Hygiene, 2002
Occupational low back pain (LBP) is a major cause of morbidity and cost. Efforts to control LBP are largely unsuccessful, and better understanding of risks is needed, especially psychological factors. The purpose of this research was to assess the association between worker attributions and LBP.

The back stress in high temperature deformation

Acta Metallurgica, 1969
Abstract The applicability of the following strain rate equation to high temperature deformation is examined. e=|gf s exp ( −ΔH 0 KT ) exp ( vτ − τB] KT ) Here e is the tensile or compressive strain rate; φs is a structure factor; ΔH0 is the activation enthalpy in the absence of effective stress; v is the activation ...
