The effect of hip and knee joint calibration methods on muscle-tendon length and velocity in modelling gait

Musculoskeletal models can be used to distinguish too short or too slow muscles in Cerebral Palsy patients. Therefor muscle-tendon geometry needs to be modeled accurately in order to predict the need and effectiveness of muscle-tendon lengthening. This geometry is strongly related to the location and orientation of the joint centres. In clinic...

Predicting muscle forces in the shoulder by constraining the inverse optimisation with EMG and a forward muscle model

The Dutch Shoulder and Elbow Model (DSEM) is a musculoskeletal model of the shoulder that can be used to predict internal shoulder loading (muscle forces, joint reaction forces, etc.). The DSEM uses an inverse optimisation method to predict muscle forces from net joint moments. In this study two new modes are presented that constrain the inverse...
