receiving more attention in the research literature is the prolonged stooped posture. There are a number
of industries (agriculture and construction to name two) that require these prolonged stooped postures
as part of the standard work activity and our current ability to quantify the risk associated with these
postures is quite limited. In the stooped posture, the mass of the upper body is often supported
through a passive mechanism that includes tension in the posterior spinal ligaments and fascia as well
as compression in the spine itself. If the stooped posture is maintained, the viscoelastic properties of
these passive tissues needs to be considered, which means that the time spent in the posture and the
