Recent developments in muscle synergy analysis in young people with neurodevelopmental diseases: A Systematic Review

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.

A quantitative taxonomy of human hand grasps [PDF]

, 2019
Background: A proper modeling of human grasping and of hand movements is fundamental for robotics, prosthetics, physiology and rehabilitation. The taxonomies of hand grasps that have been proposed in scientific literature so far are based on qualitative ...

Task constraints and minimization of muscle effort result in a small number of muscle synergies during gait

Frontiers in Computational Neuroscience, 2014
Finding muscle activity generating a given motion is a redundant problem, since there are many more muscles than degrees of freedom. The control strategies determining muscle recruitment from a redundant set are still poorly understood.

Evidence for altered upper extremity muscle synergies in chronic stroke survivors with mild and moderate impairment

Frontiers in Human Neuroscience, 2015
Previous studies indicate that motor coordination may be achieved by assembling task-dependent combinations of a few muscle synergies, defined here as fixed patterns of activation across a set of muscles.

Muscle Synergies During Walking in Children With Cerebral Palsy: A Systematic Review

Frontiers in Physiology, 2020
Background: Walking problems in children with cerebral palsy (CP) can in part be explained by limited selective motor control. Muscle synergy analysis is increasingly used to quantify altered neuromuscular control during walking.

Alterations in intermuscular coordination underlying isokinetic exercise after a stroke and their implications on neurorehabilitation

Journal of NeuroEngineering and Rehabilitation, 2021
Background Abnormal intermuscular coordination limits the motor capability of stroke-affected upper limbs. By evaluating the intermuscular coordination in the affected limb under various biomechanical task constraints, the impact of a stroke on motor ...

Excitatory postsynaptic potentials in rat neocortical neurons in vitro. III. Effects of a quinoxalinedione non-NMDA receptor antagonist [PDF]

, 1990
1. Intracellular microelectrodes were used to obtain recordings from neurons in layer II/III of rat frontal cortex. A bipolar electrode positioned in layer IV of the neocortex was used to evoke postsynaptic potentials.

Muscle synergy stability and human balance maintenance [PDF]

Journal of NeuroEngineering and Rehabilitation, 2014
The signals that the central nervous system (CNS) produces and sends to the muscles to effect movement are not entirely understood. Muscle synergy theory suggests that the central nervous system produces a small number of signals that pass through a network that distributes combinations of these signals to the muscles. Though these synergies are rather
