The aim of this study was to evaluate a variety of traditional and novel surface electromyography (SEMG) characteristics of biceps brachii muscle in patients with Parkinson's disease (PD) and compare the results with the healthy old and young control subjects. Furthermore, the aim was to define the optimal biceps brachii loading level that would most likely(More)
The aim of this work was to differentiate patients with essential tremor from patients with Parkinson's disease. Electromyographic data from biceps brachii muscles and kinematic data from arms during isometric tension of the arms were measured from 17 patients with essential tremor, 35 patients with Parkinson's disease and 40 healthy controls. The EMG(More)
Interferential electromyogram (iEMG) was analyzed in healthy newborn infants (n=29) during the first 24 hours of life as a model of transition from hypogravity (intrauterine immersion) to the Earth's gravity (postnatal period). Nonlinear instruments of iEMG analysis (correlation dimension, entropy and fractal dimension) reflected the complexity, chaotic(More)
The purpose of the study was to investigate neuromuscular status in the preterm infants using surface electromyography (EMG). 10 preterm (gestational age 31/32 weeks) and 10 term infants (gestational age 38/39 weeks) participated in the study on the 2nd, 4th and 6th postnatal week. Linear and novel non-linear parameters of were used to quantitize(More)
Temporal structure of interference electromyogram (iEMG) was studied in healthy two days old human newborns (n = 76) using the non-linear parameters (correlation dimension, fractal dimension, correlation entropy). It has been found that the non-linear parameters of iEMG were time-dependent because they were decreasing within the first two days of life.(More)
The aim of this work was to differentiate patients with essential tremor from patients with Parkinson's disease. The electromyographic signal from the biceps brachii muscle was measured during isometric tension from 17 patients with essential tremor, 35 patients with Parkinson's disease, and 40 healthy controls. The EMG signals were high pass filtered and(More)
The correlation between the motor units activity patterns and clinical forms of parkinsonism has been investigated by means of surface electromyography. Grouped electromyogram, characteristic of parkinsonism shaking was found to be generated on the basis of double, triple discharges of the motor unit (doublets and triplets), or long-term synchronization of(More)
In the review we discuss the earlier postulated [1] natural motor strategies which are dependent on gravitation and temperature and which evolve during the human life span. The first of them, FM-strategy is the characteristic of the intrauterine immersion in the amniotic fluid and ofmicrogravitation in the spaceflight (G - 0). It is based on domination of(More)
Comparative neurophysiological analysis of the motor units (MU) activity during hypothermia performed in ground-squirrels and rats, revealed a tendency of the MU firing rate to decrease whereas electromyographical patterns of thermoregulatory activity were found to be common both for hibernating and non-hibernating animals. The MU activity ceased in rats at(More)
