Muscle Synergies and Clinical Outcome Measures Describe Different Factors of Upper Limb Motor Function in Stroke Survivors Undergoing Rehabilitation in a Virtual Reality Environment

Sensors, 2021
Recent studies have investigated muscle synergies as biomarkers for stroke, but it remains controversial if muscle synergies and clinical observation convey the same information on motor impairment.

Neuromuscular mechanisms of motor adaptation to repeated gait-slip perturbations in older adults

Scientific Reports, 2022
Individuals can rapidly develop adaptive skills for fall prevention after their exposure to the repeated-slip paradigm. However, the changes in neuromuscular control contributing to such motor adaptation remain unclear. This study investigated changes in

Fixed muscle synergies and their potential to improve the intuitive control of myoelectric assistive technology for upper extremities

Journal of NeuroEngineering and Rehabilitation, 2019
Background Users of myoelectric controlled assistive technology (AT) for upper extremities experience difficulties in controlling this technology in daily life, partly because the control is non-intuitive.

Neural Network Models for Spinal Implementation of Muscle Synergies

Frontiers in Systems Neuroscience, 2022
Muscle synergies have been proposed as functional modules to simplify the complexity of body motor control; however, their neural implementation is still unclear.

Evidence of synergy coordination patterns of upper-limb motor control in stroke patients with mild and moderate impairment

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,

Cortical Correlates of Locomotor Muscle Synergy Activation in Humans: An Electroencephalographic Decoding Study

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 ...

Generalizability of muscle synergies in isometric force generation versus point-to-point reaching in the human upper extremity workspace

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.

Non-negative matrix factorisation is the most appropriate method for extraction of muscle synergies in walking and running

, 2020
Muscle synergies provide a simple description of a complex motor control mechanism. Synergies are extracted from muscle activation patterns using factorisation methods. Despite the availability of several factorisation methods in the literature, the most

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.
