Synergy Optimization or SynO estimates muscle forces and activations by using the concept of muscle synergy.
These MATLAB codes are an implementation of a novel approach for estimating muscle forces/activations by imposing a synergy structure within optimization (termed “synergy optimization,” or SynO). For comparison, users can switch to a MATLAB implementation of a static optimization in the code. Sample experimental overground walking data obtained from the first knee grand challenge competition are also included. For more details about this study and project, read the following paper:
