From: Muscle synergies and spinal maps are sensitive to the asymmetry induced by a unilateral stroke
Muscle synergies. Primitive signals and weight coefficients related to extracted muscle synergies (MS1-MS3) according to the criterion of the eigenvalue > 1 and referring to all healthy and hemiparetic subjects while walking at 1.1 km/h. The averaged temporal components and the averaged weight coefficients are reported in black. Error bars refer to the standard error. White vertical lines and gray vertical bars overlapped to the primitive signals refer respectively to mean and one standard deviation of the occurrence of the contralateral heel strike.
