Abstract: In this study we investigated differences between rescaled generic and CT-based musculoskeletal models. Generic models were rescaled based on gait analysis marker locations. Subject-specific models were constructed by customizing joint kinematics and muscle trajectories using CT-based bone models. For both model types, we calculated distances between joint centers as well as peak muscle force generating capacity (FGC) and moment generating capacity (MGC) during gait. For most muscles, the subject-specific models predicted significantly higher FGC; conversely, significantly lower MGC was predicted for hip flexion, extension and exorotation. We conclude that subject-specific models are necessary to accurately predict musculoskeletal loading of the hip joint.
