From: Variability of trunk muscle synergies underlying the multidirectional movements and stability trunk motor tasks in healthy individuals

Figure 5

Representative (a) five-trunk muscle synergies (W1–W5) and (b) their temporal patterns (C1–C5). Non-negative matrix factorization on the concatenated electromyography (EMG) envelopes of 11 trunk motor tasks extracted five trunk muscle synergies for each participant. We sorted the trunk muscle synergies of all participants into five groups using hierarchical cluster analysis.
