Before revision:  Conclusions: We showed the potential of tensor factorisations to study and characterise muscle activity and developed a new direct method for shared and task-specific synergy identificationwith a constrained Tucker decomposition.
After revision:  Conclusions: We showed the potential of tensor factorisations to study and characterise muscle activity and develop a new consTD method for muscle synergy extraction that could be used for shared and task-specific synergy identificationwith a constrained Tucker decomposition.
