Muscle synergy analysis in dart throwing
2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017This study aims to analyze muscle synergies in darts throwing movement to clarify how the central nervous system (CNS) controls muscle activation to produce complicated motion. Activities of 10 different muscles on upper limb were recorded through surface electromyography (EMG) electrodes from four participants with less experience of dart throwing ...

Muscle Synergies Characterizing Human Postural Responses
Journal of Neurophysiology, 2007Postural control is a natural behavior that requires the spatial and temporal coordination of multiple muscles. Complex muscle activation patterns characterizing postural responses suggest the need for independent muscle control. However, our previous work shows that postural responses in cats can be robustly reproduced by the activation of a few ...

Neuromechanics of Muscle Synergies During Cycling
Journal of Neurophysiology, 2009Muscle synergies have been proposed as building blocks that could simplify the construction of motor behaviors. However, the muscles within synergistic groups may have different architectures, mechanical linkages to the skeleton, and biochemical properties, and these put competing demands on the most appropriate way to activate them for different ...

Cost function criteria using muscle synergies: Exploring the potential of muscle synergy hypothesis
Computer Methods and Programs in BiomedicineSolving the redundant optimization problem for human muscles depends on the cost function. Choosing the appropriate cost function helps to address a specific problem. Muscle synergies are currently limited to those obtained by electromyography. Furthermore, debate continues regarding whether muscle synergy is derived or real.

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.
