Work-related musculoskeletal disorders (WMSDs) represent approximately one third of
workers' compensation costs in US private industry, yet estimates of acceptable exposure …

Epidemiologic and experimental studies were reviewed to assess the role of postural
factors, high handgrip and pinch forces, repetitive hand and wrist movements, external …

The concept" repetitive work" refers to similar work tasks performed again and again. By
necessity, repetitive work of the upper extremity implies a motor component, which can be …

Abstract The Revised Strain Index (RSI) is a distal upper extremity (DUE) physical exposure
assessment model based on: intensity of exertion, frequency of exertion, duration per …

Completely revised and updated, taking the scientific rigor to a whole new level, the second
edition of the Occupational Ergonomics Handbook is now available in two volumes. This …

Objective: The objective was to develop an equation, for repetitive tasks, that uses frequency
and/or duty cycle (DC) to predict maximum acceptable efforts (MAE) relative to maximum …

This article provides a review of the biomechanics literature on the low back and upper
extremities. Biomechanics is the study of forces acting on and generated within the body and …

The aim of this study was to investigate the effects of a light hand tool exertion task on
shoulder muscle activation during different postures of shoulder flexion and humeral …

The objective of this research was to determine shoulder girdle fatigue for different
combinations of weight of workpieces, weight of hand-tools, shoulder postures, arm up time …

The aim of this study was to discriminate fatigue of upper limb muscles depending on the
external load, through the development and analysis of a muscle fatigue index. Muscle …
