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

Table 10

Mean value and standard deviations (SDs) related to the evaluated synergy by synergy for each task. Differences between pair of synergies in each task are reported in superscript with the relative roman number; stands for statistical differences among all synergies. The overall means evaluated considering all the synergies together are reported in italic.
