The London Lower Limb Model

 

A musculoskeletal model of the lower limb has been developed in OpenSim (Delp et al., 2007) from the anatomical dataset published by Klein Horsman et al. with the purpose of estimating muscle and joint contact forces during daily living activities. The unilateral model is composed of six bodies (pelvis, femur, patella, tibia, hind foot, mid foot plus phalanxes) connected by a spherical joint (hip), and 4 hinges patello-femoral joint, tibio-femoral joint, talocrural joint and subtalar joint). Accounting for the 6 degrees of freedom of the pelvis with respect to the ground and for the kinematic constraint used to define the patellar movement, the model has twelve degrees of freedom. A total number of 38 muscles are represented by 163 actuators. Viapoints and wrapping surfaces were introduced to improve the path of some muscles. Minor modifications were applied to the original database in order to achieve ankle joint functionality.
