Frontiers in Physiology, 2023 Objectives: Previous studies showed that the central nervous system (CNS) controls movements by recruiting a low-dimensional set of modules, usually referred to as muscle synergies. Stroke alters the structure and recruitment patterns of muscle synergies,

iScience, 2019 Summary: Muscular control during walking is believed to be simplified by the coactivation of muscles called muscle synergies. Although significant corticomuscular connectivity during walking has been reported, the level at which the cortical activity is ...

Comparison of muscle synergies for running between different foot strike patterns.
PLoS ONE, 2017 It is well known that humans run with a fore-foot strike (FFS), a mid-foot strike (MFS) or a rear-foot strike (RFS). A modular neural control mechanism of human walking and running has been discussed in terms of muscle synergies.

Frontiers in Human Neuroscience, 2023 Isometric force generation and kinematic reaching in the upper extremity has been found to be represented by a limited number of muscle synergies, even across task-specific variations.

A functional electrical stimulation system for human walking inspired by reflexive control principles [PDF]
, 2017 This study presents an innovative multichannel functional electrical stimulation gait-assist system which employs a well-established purely reflexive control algorithm, previously tested in a series of bipedal walking robots.

Are muscle synergies useful for neural control? [PDF]
Frontiers in Computational Neuroscience, 2013 The observation that the activity of multiple muscles can be well approximated by a few linear synergies is viewed by some as a sign that such low-dimensional modules constitute a key component of the neural control system. Here, we argue that the usefulness of muscle synergies as a control principle should be evaluated in terms of errors produced not ...

Evidence of muscle synergies during human grasping [PDF]
Biological Cybernetics, 2013 Motor synergies have been investigated since the 1980s as a simplifying representation of motor control by the nervous system. This way of representing finger positional data is in particular useful to represent the kinematics of the human hand. Whereas, so far, the focus has been on kinematic synergies, that is common patterns in the motion of the ...

Neuro-Modulation Analysis Based on Muscle Synergy Graph Neural Network in Human Locomotion
IEEE Transactions on Neural Systems and Rehabilitation EngineeringThe coordination of muscles in human locomotion is commonly understood as the integration of motor modules known as muscle synergies. Recent research has delved into the adaptation of muscle synergies during the acquisition of new motor skills.

Frontiers in Computational Neuroscience, 2018 Motor system uses muscle synergies as a modular organization to simplify the control of movements. Motor cortical impairments, such as stroke and spinal cord injuries, disrupt the orchestration of the muscle synergies and result in abnormal movements. In

A personalized multi-channel FES controller based on muscle synergies to support gait rehabilitation after stroke [PDF]
, 2016 It has been largely suggested in neuroscience literature that to generate a vast variety of movements, the Central Nervous System (CNS) recruits a reduced set of coordinated patterns of muscle activities, defined as muscle synergies.
