Working Postures: A Literature Review
TLDR
The literature provides evidence that working postures and musculoskeletal health are related and this relationship is supported by the overexertion, differential fatigue, and cumulative load theories of musculOSkeletal injuries' precipitation. Expand

TLDR
Vibration of heavy haul trucks frequently generated vibrations in excess of ISO standards in overburden mining operation representing a health hazard, however, in sagittal and coronal planes the whole body vibration exceeded the ISO standards many times. Expand
An Electromyographic Study of Low-Velocity Rear-End Impacts
TLDR
Muscle responses were greater with higher levels of acceleration, and the muscular component of the head–neck complex plays a central role in the abatement of higher acceleration levels, it may be a primary site of injury in the whiplash phenomenon. Expand
Low back problems and possible improvements in nursing jobs.
TLDR
The methodology proposed here is practical for job evaluation and to design a participatory ergonomic intervention aiming at reducing low back injuries in nursing jobs. Expand
Upper body push-pull strength of normal young adults in sagittal plane at three heights
Abstract Twenty young adults (ten males − mean age = 21.1 years; ten females − mean age = 21.1 years) were tested for their two-handed push-pull strength in sagittal plane at heights of 35 cm (low),Expand
Quantification of isometric cervical strength at different ranges of flexion and extension.
TLDR
Cervical strength was found to be highest in the neutral posture for both flexion and extension and significantly decreased with an increasing angular deviation of the neck and Males exerted significantly higher forces than females. Expand
An injury profile of practicing diagnostic medical sonographers in Alberta
TLDR
Increased workload/decreased staff, sustained posture or activity and equipment design were identified as factors which could result in an increase in work-related injuries among sonographers. Expand
Comparison of Ergonomic Risk Assessment Output in Four Sawmill Jobs

  • Engineering, Medicine
  • International journal of occupational safety and…
  • 1 January 2010
TLDR
Of the methods examined, the RULA and SI were best (correct classification rates of 99 and 97% respectively) and the quantitative ACGIH-TLV for mono-task hand work and Borg scale were worst (misclassification rates of 86 and 28% respectively). Expand
Musculoskeletal risk factors in cleaning occupation—A literature review
Abstract The objective of this paper is to present a systematic review of the literature in the field to identify problems, recommended practices, unresolved issues and explore occupational needsExpand
Analysis of low velocity frontal impacts.
TLDR
The muscle responses were greater with higher levels of acceleration, particularly the trapezius in frontal impacts, which may be a primary site of injury at low velocity whiplash phenomenon. Expand
