Epidural stimulation restores muscle synergies by modulating neural drives in participants with sensorimotor complete spinal cord injuries

Journal of NeuroEngineering and Rehabilitation, 2023
Multiple studies have corroborated the restoration of volitional motor control after motor-complete spinal cord injury (SCI) through the use of epidural spinal cord stimulation (eSCS), but rigorous quantitative descriptions of muscle coordination have ...

Action direction of muscle synergies in three-dimensional force space

Frontiers in Bioengineering and Biotechnology, 2015
Redundancy in the musculoskeletal system was supposed to be simplified by muscle synergies, which modularly organize muscles. To clarify the underlying mechanisms of motor control using muscle synergies, it is important to examine the spatiotemporal ...

Exoskeleton-Assisted Sit-to-Stand Training Improves Lower-Limb Function Through Modifications of Muscle Synergies in Subacute Stroke Survivors

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Abnormal muscle synergies during sit-to-stand (STS) transitions have been observed post-stroke, which are associated with deteriorated lower-limb function and mobility.

Muscle synergies in neuroscience and robotics: from input-space to task-space perspectives [PDF]

, 2013
In this paper we review the works related to muscle synergies that have been carried-out in neuroscience and control engineering. In particular, we refer to the hypothesis that the central nervous system (CNS) generates desired muscle contractions by ...

Effective force control by muscle synergies [PDF]

Frontiers in Computational Neuroscience, 2014
Muscle synergies have been proposed as a way for the central nervous system (CNS) to simplify the generation of motor commands and they have been shown to explain a large fraction of the variation in the muscle patterns across a variety of conditions. However, whether human subjects are able to control forces and movements effectively with a small set ...

A novel computational framework for deducing muscle synergies from experimental joint moments [PDF]

, 2014
Prior experimental studies have hypothesized the existence of a “muscle synergy” based control scheme for producing limb movements and locomotion in vertebrates.

A methodology for assessing the effect of correlations among muscle synergy activations on task-discriminating information [PDF]

, 2013
Muscle synergies have been hypothesized to be the building blocks used by the central nervous system to generate movement. According to this hypothesis, the accomplishment of various motor tasks relies on the ability of the motor system to recruit a ...

Cortex integrity relevance in muscle synergies in severe chronic stroke

Frontiers in Human Neuroscience, 2014
Background: Recent experimental evidence has indicated that the motor system coordinates muscle activations through a linear combination of muscle synergies that are specified at the spinal or brainstem networks level.

Muscle synergies after stroke are correlated with perilesional high gamma. [PDF]

, 2016
Movements can be factored into modules termed "muscle synergies". After stroke, abnormal synergies are linked to impaired movements; however, their neural basis is not understood. In a single subject, we examined how electrocorticography signals from the

The Existence of Shared Muscle Synergies Underlying Perturbed and Unperturbed Gait Depends on Walking Speed

Applied Sciences, 2022
Muscle synergy theory assumes that the central nervous system generates a wide range of complex motor outputs by recruiting muscle synergies with different strengths and timings.
