Abstract

The temporal structure of an interference electromyogram (iEMG) was studied in healthy one- and two-day-old human newborns (n = 76) using nonlinear parameters (correlation and fractal dimension, correlation entropy). It was found that the nonlinear parameters of iEMG were time-dependent because they decreased during the first two days of life. These parameters were also sensitive to the muscle function, because the correlation dimension, fractal dimension, and correlation entropy of iEMG of the gastrocnemius muscle differed from the same parameters of other muscles. Some nonlinear parameters were found to be independent of the iEMG amplitude. This model of early ontogenesis is expected to be useful for studying antigravitational activity.
