The experimental estimation of muscle activities in post-stroke patients with limb motor deficit is often based on surface electromyography signals (EMGs). Besides EMGs processing and interpretation difficulties, the differences in motor control of d

One possible cause of abnormal spinal column curvatures in adolescents is standing in “bad posture” for a long time. If this bad habit can be corrected on time, by creating a dynamic stereotype for correct body position maintenance, further healt

The present study was aimed at investigating the mechanism of a human stress reaction by means of Generalized Nets (GNs). A principle GN-model of the main structures, organs and systems of the human body taking part in the acute and chronic reaction

The dynamics of the upper extremity can be modeled as the motion of an open kinematic chain of rigid links, attached relatively loosely to the trunk. The upper extremity or upper limb is a complex mechanism which includes many bones, joints, and soft

Corticomuscular synchronization has been shown to occur in beta (15–30 Hz) and gamma range (30–45 Hz) during isometric compensation of static and dynamic (periodically modulated) low-level forces, respectively. However, it is still unknown to wha

The objective of this study is to better understand the role of proprioception in handwriting and test earlier conclusions stating that the automated shaping of letters was not impaired by the removal of visual control in deafferentation. To this aim

This study was performed to evaluate the relative significance of changes typical for muscle fatigue on quantitative parameters obtained from turns analysis of simulated intramuscular and surface interference electromyographic (EMG) signals. Effects

Recently, we studied corticomuscular coherence (CMC) in a visuomotor task and showed for the first time gamma-range (30–45 Hz) CMC during isometric compensation of a periodically modulated dynamic force. We speculated that for the control of such f

In a series of papers we have described the human body, its separate systems, and their behavior using Generalized Nets (GNs). Here we construct a GN-model that represents auditory information processing - the first on our research on the structure a
