Mechanical Predictors of Discomfort during Load Carriage
Discomfort during load carriage is a major issue for activities using backpacks (e.g. infantry maneuvers, children carrying school supplies, or outdoor sports). It is currently unclear which mechanical parameters are responsible for subjectively perceived discomfort. The aim of this study was to identify objectively measured mechanical predictors of discomfort during load carriage. We compared ...
متن کاملValidation of an instrumented dummy to assess mechanical aspects of discomfort during load carriage
Due to the increasing load in backpacks and other load carriage systems over the last decades, load carriage system designs have to be adapted accordingly to minimize discomfort and to reduce the risk of injury. As subject studies are labor-intensive and include further challenges such as intra-subject and inter-subject variability, we aimed to validate an instrumented dummy as an objective lab...
متن کاملModeling mechanical strains and stresses in soft tissues of the shoulder during load carriage based on load-bearing open MRI.
Shoulder strain is a major limiting factor associated with load carriage. Despite advances in backpack designs, there are still reports of shoulder discomfort, loss of sensorimotor functions, and brachial plexus syndrome. The current study is aimed at characterizing mechanical loading conditions (strains and stresses) that develop within the shoulder's soft tissues when carrying a backpack. Ope...
متن کاملCan load carriage system weight, design and placement affect pain and discomfort? A systematic review.
PURPOSE A systematic review of the literature was conducted to answer the following questions: 1. Does usage or weight of load carriage system cause pain, perceived exertion or discomfort? 2. Can load carriage system placement on the spine influence pain, perceived exertion or discomfort? 3. Can load carriage system design influence the amount of pain, perceived exertion or discomfort caused by...
متن کاملDynamic analysis of load carriage biomechanics during level walking.
This paper describes an investigation into the biomechanical effects of load carriage dynamics on human locomotion performance. A whole body, inverse dynamics gait model has been developed which uses only kinematic input data to define the gait cycle. To provide input data, three-dimensional gait measurements have been conducted to capture whole body motion while carrying a backpack. A nonlinea...
