Abstract EN
Muscle synergy has been applied to comprehend how the central nervous system (CNS) controls movements for decades.
However, it is not clear about the motion control mechanism and the relationship between motions and muscle synergies.
In this paper, we designed two experiments to corroborate the hypothesis: (1) motions can be decomposed to motion primitives, which are driven by muscle synergy primitives and (2) variations of motion primitives in direction and scale are modulated by activation coefficients rather than muscle synergy primitives.
Surface electromyographic (EMG) signals were recorded from nine muscles of the upper limb.
Nonnegative matrix factorization (NMF) was applied to extract muscle synergy vectors and corresponding activation coefficients.
We found that synergy structures of different movement patterns were similar (α=0.05).
The motion modulation indexes (MMI) among movement patterns in reaching movements showed apparent differences.
Merging coefficients and reconstructed similarity of synergies between simple motions and complex motions were significant.
This study revealed the motion control mechanism of the CNS and provided a rehabilitation and evaluation method for patients with motor dysfunction in exercise and neuroscience.
