“…Calculation of muscle and joint forces represent a challenging modeling application [3], [4]. Because musculoskeletal geometry and tissue properties can vary markedly among individuals, the accuracy of generic models has been questioned [5], [6], particularly when studying musculoskeletal disorders [7], [8]. Conversely, subject-specific models allow inclusion of individual musculoskeletal anatomy and properties, providing an alternative approach to calculating muscle moment arms [9], [10], muscle and joint forces [11], [12], bone and cartilage stresses [13], [14].…”

“…As discussed by Wagner and colleagues (Wagner et al 2013), the ability to derive consistent results from generic musculoskeletal models implemented by different researchers in different platforms is a critical need for the advancement of our field. Across new platforms, we expect that the benchmarking simulations provided here will help future users evaluate the consistency of their results in the context of our original implementation of the model.…”

“…Computational approaches to deriving inputs and calculating the dynamic behavior of a musculoskeletal system are conceptually similar across platforms, and include common modeling and simulation components such as descriptions of joint kinematics and range of motion, damping, passive and active force generators, dynamics engines to solve the equations of motion, and numerical integrators. Despite the conceptual similarities, technical differences in the implementation of computational algorithms can influence simulation output (Wagner et al 2013). In addition, direct replication of published simulation results remains a challenge for our community for a number of reasons.…”

“…Moreover, it is difficult to estimate the co-contraction of agonist and antagonist muscles using a musculoskeletal model. This is because an optimization scheme for the approximate minimization of muscle stress is typically used to estimate muscle activation patterns in musculoskeletal models [18]. Antagonist muscle activation increases the metabolic cost and is not selected by such schemes.…”
