如果采取不良姿势，长时间坐着会导致长期肌肉骨骼问题。建立了用于计算第五腰椎间盘椎间盘压缩的人体三维静态模型。 SAMMIE 是一种计算机辅助人体工程学软件包，用于对计算机操作员工作站进行建模并确定坐姿下的关节中心位置和关节角度。还进行了实验以确定所用座椅上的体重分布。男性和女性体重分布没有发现显着差异。静态模型找到了座板和靠背倾斜的姿势，以预测最低的椎间盘压缩。操作者向前弯曲的姿势会产生最高的椎间盘负载。
Prolonged seating can cause musculo-skeletal problems in the long term if poor postures are adopted. A three dimensional static model of the body to calculate the intervertebral disc compression at the fifth lumbar disc was built. SAMMIE, a computer aided ergonomics package was used for modelling a computer operator workstation and determination of joint centre locations and joint angles in a seated posture. Experimentation was also performed to determine the body-mass distribution on the seat used. No significant difference between male and female body-mass distribution was found. The static model found postures with the seat pan and backrest reclined to predict the lowest disc compression. Postures in which the operator was bent forwards gave the highest disc loadings.
