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 ...

A Cable-Driven Upper Limb Rehabilitation Robot With Muscle-Synergy-Based Myoelectric Controller
IEEE Transactions on roboticsSurface electromyography (sEMG) signal has been used in upper limb rehabilitation robots (ULRR). However, existing ULRR based on myoelectric controllers suffers from limited generalization ability in estimating three-dimensional (3-D) motion intention ...

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.

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 ...

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 ...

Developmental Changes of Muscle Synergies in an Infant's Walking
2023 45th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2023Primitive stepping is one of the primitive reflexes in newborns in response to external stimuli. It is known that primitive stepping disappears about two months after birth, but its role and the relationship with voluntary gait acquired later are still unknown. In this study, we extracted muscle synergies, spatiotemporal coordination patterns of muscle

Effect of Assist Robot on Muscle Synergy during Sit-to-Stand Movement
International Symposium on Robotics, 2021Sit-to-Stand (STS) is an important movement in daily life and could be difficult for older people. Assist robot is expected to provide STS support. STS movement does not only require kinetic coordination, but also muscle coordination. Thus, understanding

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 ...
