Knee torque estimation in sit to stand transfer

Abstract Multi-body formulations of human body has been a major approach in biomechanics to study the kinematics and dynamics of human movements. This paper discuss an inverse dynamics model of human body for the estimation of knee torque requirement during a sit to stand (STS) transfer. The study was carried out in two parts. In the first part of the study, angular deviations of trunk and knee were recorded in the sagittal plane, while one participant performed STS transfer. In the second part of the study, a five segment human model was designed in SolidWorks and later analysed in MSC/ADAMS for computation of knee torque in STS transfer. The maximum knee torque was found to be 1.34 Nm/kg at 59.2° knee extension.
