Awkward 
Posture 
Any fixed or constrained body position that overloads muscles, tendons, or 
joints. Generally, the more a joint deviates from the neutral position the more 
the posture is considered to be 'awkward' and the greater the risk of injury 
Biomechanics 
The study of the effects of internal and external forces on the human body both 
in movement and at rest. • Models calculate the levels of force (compression 
and shear) and torque that the joints, tendons, muscles, and ligaments are 
required to withstand and/or generate. • The calculated forces and/or torques 
are compared to recognized limits to evaluate the acceptability of a task, 
activity, etc. 
Bursitis 
Bursae are lubricating, fluid filled pads that separate tendons from bones in 
some joints of the body (e.g. shoulder). • Bursitis is the result of the 
inflammation of a bursae. The inflammation may be caused by repetitive 
and/or forceful exertions at the joint 
Contact Stress 
Exposure of a body part to a hard or sharp surface/edge from a workstation or 
a hand tool, e.g. leaning forearms against the sharp edge of a desk/table. • 
Contact stress has been associated with the development of some WMSDs
