Assessment of Postural Muscular Synergies

The control of posture and movement in humans appears to be challenging because of the many degrees-of-freedom (DOFs) of our musculoskeletal system. Previous chapters have focused on the problem of kinematic redundancy, and it was shown that several experimental scenarios have highlighted the presence of postural kinematic synergies (such as Donders’ law), i.e. specific patterns of joints covariation that ‘eliminate’ kinematic redundancy by reducing the effective number of available kinematic DOF.
