A suite of objective biomechanical measurement tools for personal load carriage system assessment

Article Abstract:

Canadian forces have undertaken a research conducted by Defence Research and Development Canada (DRDC)-Toronto through a series of contracts to the Ergonomics Research Group of QueenEs University to investigate and understand the factors affecting human load carriage performance and its development. The approach led to development of objective performance criteria for load carriage systems and to improvements in load carriage designs that could be used both in military and in general.

Initial force and postural adaptations when pushing and pulling on floor surfaces with good and reduced resistance to slipping

Article Abstract:

A study to see whether the kinematics and kinetics of pushing and pulling of heavy objects in any way is linked to the frictional properties of different types of floor surfaces is presented. The observation revealed that when the handlers are pulling or pushing heavy objects they adjust their posture and the direction of hand and foot in such a way that it reduces the levels of floor friction and thus protects them from musculoskeletal injuries.

Variation in sitting pressure distribution and location of the points of maximum pressure with rotation of the pelvis, gender and body characteristics

Article Abstract:

An experiment that was carried out on subjects sitting on a flat, hard and horizontal support at various angle of the rotation of the pelvis in order to study the pressure distribution and the points of maximum pressure i.e. below the ischial tuberosites is discussed. The angle of rotation of the pelvis and the distance between the maximum pressure points by gender helped to show the maximum pressure and the pressure gradient.
