Development and validation of an easy-to-use risk assessment tool for cumulative low back loading
The Lifting Fatigue Failure Tool (LiFFT) Recent evidence suggests that musculoskeletal disorders (MSDs) may be the result of a fatigue failure process in affected tissues. This paper describes a new low back exposure assessment tool (the Lifting Fatigue Failure Tool [LiFFT]), which estimates a “daily dose” of cumulative loading on the low back using fatigue failure principles. Only three variables are necessary to derive the cumulative load associated with a lifting task: the weight of the load, the maximum horizontal distance from the spine to the load, and the number of repetitions...
A multi-component patient-handling intervention improves attitudes and behaviors for safe patient handling and reduces aggression experienced by nursing staff
A controlled before-after study This study evaluated an intervention for patient-handling equipment aimed to improve nursing staffs' use of patient handling equipment and improve their general health, reduce musculoskeletal problems, aggressive episodes, days of absence and work-related accidents. As a controlled before-after study, questionnaire data were collected at baseline and 12-month follow-up among nursing staff at intervention and control wards at two hospitals. At 12-month follow-up, the intervention group had more positive attitudes towards patient-handling equipment and increased...
Patient transfers and assistive devices
Prospective cohort study on the risk for occupational back injury among healthcare workers Objectives : This prospective cohort study investigates work-related risk factors for occupational back injury among healthcare workers. Methods : The study comprised 5017 female healthcare workers in eldercare from 36 municipalities in Denmark who responded to a baseline and follow-up questionnaire in 2005 and 2006, respectively. Using logistic regression, the odds for occupational back injury (ie, sudden onset episodes) in 2006 from patient transfers in 2005 was modeled. Results : In the total study population...
Paramedics on the job
Dynamic trunk motion assessment at the workplace Many paramedics' work accidents are related to physical aspects of the job, and the most affected body part is the low back. This study documents the trunk motion exposure of paramedics on the job. Nine paramedics were observed over 12 shifts (120 h). Trunk postures were recorded with the computer-assisted CUELA measurement system worn on the back like a knapsack. Average duration of an emergency call was 23.5 min. Sagittal trunk flexion of >40° and twisting rotation of >24° were observed in 21% and 17% of time-sampled postures...
Impacts biomécaniques et ergonomiques de la manutention chez les travailleurs obèses
L’obésité est un problème émergent qui semble s’immiscer dans les problématiques de santé et sécurité du travail. La prévalence de blessures musculo-squelettiques chez les individus obèses et les coûts indirects (non médicaux) sont plus élevés que ceux des travailleurs ayant un poids santé. Sachant qu’une hausse soutenue du taux d’obésité chez les travailleurs est observée au Canada, il est important de s’intéresser à la problématique...
