Development of a Novel Counterweight Design for Sit to Stand Workstations

越来越多的人保持坐姿的时间越来越长。有明确的证据表明，长时间保持坐姿与腰痛的发病率较高有关。腰痛与长时间坐着办公和工业工作之间的联系促使人们采取了包括站立和坐姿交替的预防策略。工作时坐立交替的策略已被证明可以减少腰痛，对工作效率的影响最小。为了适应这种姿势的变化，需要一个可变高度的工作表面，称为坐立工作站。目前的技术使这些工作站无法满足用户高度调节，腿部间隙和到达信封的人体工程学标准。这一研究伙伴关系的目标是结合目前的研究，在长时间站立和坐着的工作和伤害的预防

An increasing percentage of the population is spending longer and longer periods of time in seated postures. There is clear evidence that longer exposures to seated postures are linked with higher rates of reported low back pain. This association between low back pain and prolonged seated office and industrial work has driven preventative strategies that involve alternating standing and sitting postures. The strategy of alternating sit and stand while working has been shown to reduce perceived low back pain and have minimal impact on work efficiency. To accommodate this change in postures a variable height work surface is required, referred to as sit to stand workstations. Current technology prevents these workstations from meeting ergonomic standards of user height accommodation, leg clearance and reach envelopes. The goal of this research partnership is to incorporate current research on the prevention of injuries during prolonged standing and seated work and
