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

Table 2

Interclass correlation coefficient (ICC) evaluated among sessions of variability account for values in the 4-synergy model for all tasks and for global EMG matrix and each muscle. Cells indicate the range of ICC values.
