<abstract>Estimates of spinal forces are quite sensitive to model assumptions, especially regarding antagonistic co-contraction. Optimization based models predict co-contraction to be absent, while electromyography (EMG) based models take co-contraction into account, but usually assume equal activation of deep and superficial parts of a muscle. The aim of this study was to compare EMG based and optimization based estimates of spinal forces in a wide range of work tasks</abstract>
