Mechanical and psychosocial work exposures: the construction and evaluation of a gender-specific job exposure matrix (JEM)
Objectives: The aim of this study was to (i) construct and evaluate a gender-specific job exposure matrix (JEM) for mechanical and psychosocial work exposures and (ii) test its predictive validity for low-back pain. Methods: We utilized data from the Norwegian nationwide Survey of Living Conditions on work environment in 2006 and 2009. We classified occupations on a 4-digit level based on the Norwegian version of the International Standard Classification of Occupations (ISCO-88). The mechanical and psychosocial exposure information was collected by personal telephone interviews and included exposures...
Aide et soin à la personne - Dossier
En France, plus de 3,5 millions de professionnels travaillent dans l'aide et le soin à la personne. Ce secteur, qui emploie majoritairement du personnel féminin, est toujours en pleine croissance et marqué par une grande diversité d'acteurs. Certains exercent en établissement, d'autres au domicile d'un bénéficiaire avec, d'un lieu à l'autre, des conditions d'intervention et des moyens extrêmement variables. Source: (2018).

Relations between work and upper extremity musculoskeletal problems (UEMSP) and the moderating role of psychosocial work factors on the relation between computer work and UEMSP
Purpose: Computer work has been identified as a risk factor for upper extremity musculoskeletal problems (UEMSP). But few studies have investigated how psychosocial and organizational work factors affect this relation. Nor have gender differences in the relation between UEMSP and these work factors been studied. We sought to estimate: (1) the association between UEMSP and a range of physical, psychosocial and organizational work exposures, including the duration of computer work, and (2) the moderating effect of psychosocial work exposures on the relation between computer work and UEMSP. Methods...
Temporal relationships between job strain and low-back pain
To our knowledge this is one of the first studies to examine reciprocal relationships between job strain and back pain and which accounts for time-invariant characteristics. The study highlights a need for more work to establish if there are bidirectional relationships, with more frequent repeat measurements and which account for time-stable individual factors.

Allied Health Professionals and Work-Related Musculoskeletal Disorders
A Systematic Review Work-related musculoskeletal injuries and disorders (WMSD) are a significant issue in the health care sector. Allied Health professionals (AHP) in this sector are exposed to physical and psychosocial factors associated with increased risk of developing a WMSD. Clarification of relevant hazard and risk factors for AHP is needed to improve understanding and inform WMSD risk management. A systematic analysis of the literature was undertaken to determine prevalence and risk factors for WMSD in AHP. Databases of Ovid MEDLINE, CINAHL (EBSCO), EMBASE and the Cochrane Database of Systematic...
Effect of individually tailored biopsychosocial workplace interventions on chronic musculoskeletal pain and stress among laboratory technicians

OBJECTIVES: This study investigated the effect of a multifaceted worksite intervention on pain and stress among laboratory technicians with chronic musculoskeletal pain using individually tailored physical and cognitive elements. STUDY DESIGN: This trial uses a single-blind randomized controlled design with allocation concealment in a 2-armed parallel group format among laboratory technicians. The trial "Implementation of physical...
Work demands and health consequences of organizational and technological measures introduced to enhance the quality of home care services
This study of home care workers in a Norwegian municipality aimed to examine the effect of two measures involving organizational (job checklists) and technological (personal digital assistants) job aids on perceived work demands and musculoskeletal health. Questionnaire data was collected in 2009 (n = 138, response rate 76.2%) and 2011 (n = 80, response rate 54%). Forty-six home care workers responded at both waves. Respondents were assigned into ‘high', ‘moderate' and ‘low' strain groups based on their responses to open and closed survey questions regarding impact...
Troubles musculosquelettiques et santé psychologique
Démarche de soutien aux activités de prise et de répartition des appels d'urgence 9-1-1 La présente étude constitue un prolongement des recherches antérieures ayant pour objectif de réduire les risques psychosociaux associés aux troubles musculosquelettiques et de santé psychologique chez les préposés des centres d'urgence 9-1-1. Elle se fonde plus précisément sur la précédente recherche (Toulouse et coll., 2011) dont les résultats suggéraient la nécessité...
Psychophysiological responses in experienced firefighters undertaking repeated self-contained breathing apparatus tasks
In order to safely and effectively extinguish fires and rescue life, firefighters are required to routinely wear self-contained breathing apparatus (SCBA), yet little is known about the specific physiological and psychological demands associated with repeated exposure to tasks that require SCBA. A total of 12 experienced firefighters took part in a series of commonly encountered SCBA activities: free search, guideline search and live firefighting tasks under room temperature (∼20°C) and extreme heat (∼180°C) conditions to assess changes in heart rate, blood pressure, mood, perceived...
Health beliefs, low mood, and somatizing tendency: contribution to incidence and persistence of musculoskeletal pain with and without reported disability
Objective This study aims to investigate whether associations of psychological risk factors with the incidence and persistence of disabling musculoskeletal pain differ from those for non-disabling musculoskeletal pain. Methods As part of the international Cultural and Psychosocial Influences in Disability (CUPID) study, 1105 Spanish nurses and office workers were asked at baseline about health beliefs concerning pain, mental health, and somatizing tendency. Musculoskeletal pain in the past months at ten anatomical sites (back, neck, and left and right shoulder, elbow, wrist/hand, and knee) was...
The influence of mental load on muscle tension
We examined the differences in muscle tension and in physiological measures depending on the type of mental task. Fifteen participants performed tests for sustained attention, vigilance and maintaining posture only. We analysed electromyogram (EMG) measures of extensor digitorum (ED), flexor carpi ulnaris (FU), deltoideus (DE) and trapezius (TR), and heart rate (HR) and respiratory frequency (RF). Measures indicated higher values for mental tasks than for maintained posture only with significant differences in all measures. The following relationships were also significant: between DE and physiological...
Body posture as an indicator of workload in mental work
OBJECTIVE: For this article, the relationships between body posture and workload for four mental tasks simulated on a computer were studied. BACKGROUND: Human behaviors are observable during work and are related to human mental activities. A novel supplementary method, based on human behavior but not directly related to task execution, is proposed to assess the workload in mental work situations. METHOD: Body posture was quantitatively analyzed with the use of a video-based analysis system. The distance between a participant's head and the display, the distance between the shoulder and the...
Étude pour intervenir sur la réduction des troubles musculo-squelettiques et de santé psychologique dans les centres d’appels d’urgence 911 de la sécurité publique municipale
Une recherche multidisciplinaire a permis de mieux cerner les dimensions de la charge mentale en lien avec les TMS et les problèmes de santé psychologique des préposés des centres d’appels d’urgence 9-1-1, profession qui a été jusqu’à maintenant peu étudiée par les chercheurs. L’étude démontre que leur travail est loin d’être celui « d’un simple répartiteur d’appels » puisqu’ils doivent faire face avec efficacité à la gestion du flux...
Physiological and Psychophysical Comparison Between a Lifting Task With Identical Weight but Different Coupling Factors
Adams, KJ, DeBeliso, M, Sevene-Adams, PG, Berning, JM, Miller, T, and Tollerud, DJ. Physiological and psychophysical comparison between a lifting task with identical weight but different coupling factors. J Strength Cond Res 24(2): 307-312, 2010-The objective of the revised NIOSH (National Institute for Occupational Safety and Health) lifting equation is to prevent or reduce lifting-related injuries. The coupling component of the equation relates to quality of the grip (i.e., hand-to-object interface) and can be rated good, fair, or poor. Good coupling is theorized to reduce lifting stress, whereas...
