MUSCLE SYNERGY SPACE: LEARNING MODEL TO CREATE AN OPTIMAL MUSCLE SYNERGY [PDF]
Frontiers in Computational Neuroscience, 2013 Muscle redundancy allows the central nervous system (CNS) to choose a suitable combination of muscles from a number of options. This flexibility in muscle combinations allows for efficient behaviors to be generated in daily life.

Evaluation of Synergy Extrapolation for Predicting Unmeasured Muscle Excitations from Measured Muscle Synergies [PDF]
Frontiers in Computational Neuroscience, 2020 Electromyography (EMG)-driven musculoskeletal modeling relies on high-quality measurements of muscle electrical activity to estimate muscle forces. However, a critical challenge for practical deployment of this approach is missing EMG data from muscles ...

Differences between kinematic synergies and muscle synergies during two-digit grasping [PDF]
Frontiers in Human Neuroscience, 2015 International audienceThe large number of mechanical degrees of freedom of the hand is not fully exploited during actual movements such as grasping. Usually, angular movements in various joints tend to be coupled, and EMG activities in different hand ...

Muscle Synergy Alteration of Human During Walking With Lower Limb Exoskeleton
Frontiers in Neuroscience, 2019 Muscle synergy reflects inherent coordination patterns of muscle groups as the human body finishes required movements. It may be still unknown whether the original muscle synergy of subjects may alter or not when exoskeletons are put on during their ...

Empirical Evaluation of Voluntarily Activatable Muscle Synergies [PDF]
Frontiers in Computational Neuroscience, 2017 The muscle synergy hypothesis assumes that individual muscle synergies are independent of each other and voluntarily controllable. However, this assumption has not been empirically tested.

The human sensorimotor cortex fosters muscle synergies through cortico-synergy coherence
NeuroImage, 2019 In neuromotor control, the dimensionality of complex muscular activation patterns is effectively reduced through the emergence of muscle synergies. Muscle synergies are tailored to task-specific biomechanical needs. Traditionally, they are considered as low-dimensional neural output of the spinal cord and as such their coherent cortico-muscular ...
