The neural origin of muscle synergies [PDF]
Frontiers in Computational Neuroscience, 2013 Muscle synergies are neural coordinative structures that function to alleviate the computational burden associated with the control of movement and posture. In this commentary, we address two critical questions: the explicit encoding of muscle synergies in the nervous system, and how muscle synergies simplify movement production.

Classification of gait phases based on a machine learning approach using muscle synergy
Frontiers in Human Neuroscience, 2023 The accurate detection of the gait phase is crucial for monitoring and diagnosing neurological and musculoskeletal disorders and for the precise control of lower limb assistive devices.

Higher-order tensor decompositions for muscle synergy analysis [PDF]
, 2019 This doctoral thesis outlines several methodological advances in the application of higher-order tensor decomposition for muscle synergy analysis estimated from surface Electromyogram (EMG). This entails both assessing current muscle synergy extraction

The case for and against muscle synergies [PDF]
Current Opinion in Neurobiology, 2009 A long standing goal in motor control is to determine the fundamental output controlled by the CNS: does the CNS control the activation of individual motor units, individual muscles, groups of muscles, kinematic or dynamic features of movement, or does it simply care about accomplishing a task?

Frontiers in Neurorobotics, 2023 Introduction The time-varying and individual variability of surface electromyographic signals (sEMG) can lead to poorer motor intention detection results from different subjects and longer temporal intervals between training and testing datasets.

Difference in muscle synergies of the butterfly technique with and without swimmer’s shoulder
Scientific Reports, 2022 This study aimed to investigate whether muscle synergy differs between swimmers with and without swimmer's shoulder in the butterfly technique. Muscle synergies, which can assess muscle coordination, were analyzed using surface electromyography.

Effects of muscle fatigue on multi-muscle synergies [PDF]
Experimental Brain Research, 2011 We studied the effects of fatigue of ankle dorsiflexors on multi-muscle synergies defined as co-varied adjustments of elemental variables (M-modes) that stabilize a task-related performance variable (trajectory of the center of pressure, COP). M-modes were defined as muscle groups with parallel changes in activation levels.

Frontiers in Bioengineering and Biotechnology, 2023 The central nervous system simplifies motor control by sending motor commands activating groups of muscles, known as synergies. Physiological locomotion can be described as a coordinated recruitment of four to five muscle synergies.

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.
