Tongue articulators as muscle synergies
The Journal of the Acoustical Society of America, 1996Tongue movements during speech production were investigated by means of a simple yet realistic biomechanical model, based on a finite-element modeling of soft tissues, in the framework of the equilibrium-point hypothesis (λ model) of motor control. The model has been exploited to estimate the ‘‘central’’ control commands issued to the muscles, for a ...

Effects of hand muscle function and dominance on intra-muscle synergies
Human Movement Science, 2022The goal of the study was to explore the effects of hand dominance and muscle function (prime mover vs. supporting muscle) on recently discovered intra-muscle synergies as potential windows into their neural origin. Healthy right-handed subjects performed accurate cyclical force production tasks while pressing with the middle phalanges and distal ...

Impaired lower limb muscle synergies post-stroke
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009Given the impaired motor output of the lower limb post-stroke, we argue that cortical damage alters the modular control structure underlying muscle activation patterns during both static and dynamic tasks. Muscle synergies were extracted from EMG collected during isometric hip torque production performed by chronic stroke and control subjects.

Muscle Synergies for Turning During Human Walking
Journal of Motor Behavior, 2017Muscle synergy describes reduced set of functional muscle co-activation patterns. We aimed to identify muscle synergies of turning compared with straight walking. Twelve healthy adults (men: 7, women: 5) performed straight walking (SW), left turning (LT), and right turning (RT) at self-selected speeds.

Altered bilateral muscle synergies after stroke
Behavioral and Brain Sciences, 1996AbstractUsing movement disorders to understand the central nervous system's goals for motor behaviour may be easier in neurological models with a focal lesion of sudden onset, because the distinction between primary and adaptive changes may be clearer than in slowly progressive and/or diffuse neurological disease.

Muscle modes and synergies during voluntary body sway
Experimental Brain Research, 2007We studied the coordination of muscle activity during voluntary body sway performed by human subjects at different frequencies. Subjects stood on the force platform and performed cyclic shifts of the center of pressure (COP) while being paced by the metronome.

Control of Muscle Synergies by Cortical Ensembles
2009Since its introduction in the early 1980s, the concept of a "preferred direction" for neuronal discharge has proven to be a powerful means of studying diverse properties of individual neurons in the motor areas of the brain. More recently, the activity recorded from ensembles of neurons, each with an identified preferred direction, has been used to ...

Muscle Synergies for Motor Control Evaluation
2018Muscle synergies have been proposed to be a modular organization for muscle coordination that map high-level task goals, or motor intentions, into motor actions. Muscle synergies and other types of modular organization have been used to explain muscle coordination during a variety of motor behaviors in many different species.
