“…Also, results obtained using a stationary bar and moveable cart were comparable in terms of force exertion and body posture (de Looze et al 2000). In addition, dynamic tasks may be simulated with static forces when the applied tasks involve slow movements (Grant andHabes 1997, Resnick andChaffin 1995). Third, the influence of the examined factors on the dependent measures investigated is limited to maximal force production.…”

Pushing and pulling are common occupational exertions that are increasingly associated with musculoskeletal complaints. This study focuses on the sensitivity of shoulder capacity to gender, handle height, exertion type (push or pull) and handle orientation for these tasks. All factors except for handle orientation influenced unilateral and total manual force strength (p < 0.01), with exertion type being the most influential. Interaction effects also existed between handle height and exertion type. Additionally, joint moments at the shoulders and low back were influenced by all factors studied (p < 0.01), with exertion type again being most influential. Knowledge of the relative influence of multiple factors on shoulder capacity can provide guidance regarding these factors when designing or evaluating occupational pushing and pulling tasks for a diverse population. Practitioner Summary: pushing and pulling comprise nearly half of all manual materials handling tasks. Practitioners often assess, design or modify these tasks while incorporating constraints, including manual force direction and handle interface. This study provides guidance to aid design of pushing and pulling tasks in the context of shoulder physical capacity.

“…In much the same way as in lithic archaeology, decades of research has been dedicated to trying to understand how tool form attributes influence an individual's ability to use modern cutting technology (e.g. Aldien et al 2005;Atkins, Xu, and Jeronimidis 2004;Atkins 2006Atkins , 2009Claudon and Marsot 2006;Grant and Habes 1997;Magnusson et al 1987;McCarthy, Hussey, andGilchrist 2007, 2010;McGorry 2001;McGorry, Dowd, andDempsey 2003, 2005). Contrary to many archaeological studies, however, mechanical and ergonomic literature has been able to dedicate a great deal of attention to the scientific understanding of exactly how different form attributes influence a tool's cutting abilities.…”

The functional value of a stone tool is principally in its ability to cut, split, or otherwise deform material. The relative efficiency with which stone tools undertake cutting processes has been a point of interest to lithic archaeologists for decades, with many linking aspects of tool morphology to functional performance. Many of the questions asked by stone tool research are, however, pertinent to other disciplines. This includes mechanical engineering and ergonomic sciences where there is a substantial amount of research dedicated to understanding the mechanics of cutting and the influence exerted by tool-form attributes during use. These investigations therefore have valuable insights for lithic archaeology and our understanding of the variables that would have been influencing stone tool use in past populations. Here, the value of mechanical and ergonomic research to lithic archaeology is analyzed, key morphological and mechanical principles central to the determination of a stone tool's cutting efficiency are reviewed, and the need for future experiments that investigate these principles within archaeological contexts is highlighted.

“…A general lack of quantitative field studies in meat industry has been expressed (Marklin and Monroe, 1998). Most knowledge about WMSD due to slaughterhouse operations is from experimental studies investigating the effect of cutting force and muscle activity (Grant and Habes, 1997;Madeleine et al, 1999) during specific limb movements, rather than during functional and in vivo work activities (Juul-Kristensen et al, 2002). Quantitative biomechanical analysis can be used to identify motor patterns during work.…”
