On the Reliability and Repeatability of Surface Electromyography Factorization by Muscle Synergies in Daily Life Activities

Figure 6

Mean value of muscle synergy vectors in the 4-synergy model related to each daily life activities. The mean has been obtained by averaging across subjects the muscle synergy vector mean of the three sessions of each subject. For visualization purposes, muscle synergy vectors are normalized to unity. Muscle numbers: 1: TFL; 2: REF; 3: VLAT; 4: VMED; 5: PERO; 6: TA; 7: SOL; 8: GLU; 9: SEMT; 10: BIF; 11: LGAS; 12: MGAS.
