Consistency of Muscle Synergies Extracted via Higher-Order Tensor Decomposition Towards Myoelectric Control |
Abstract | ||
---|---|---|
In recent years, muscle synergies have been proposed for proportional myoelectric control. Synergies were extracted using matrix factorisation techniques (mainly non-negative matrix factorisation, NMF), which requires identification of synergies to tasks or movements. In addition, NMF methods were viable only with a task dimension of 2 degrees of freedoms (DoFs). Here, the potential use of a higher-order tensor model for myoelectric control is explored. We assess the ability of a constrained Tucker tensor decomposition (consTD) method to estimate consistent synergies when the task dimensionality is increased up to 3-DoFs. Synergies extracted from 3

-order tensor of 1 and 3 DoFs were compared. Results showed that muscle synergies extracted via consTD were consistent with the increase of task-dimension. Hence, these results support the consideration of proportional 3-DoF myoelectric control based on tensor decompositions. |
