MODIFICĂRILE PARAMETRILOR DE BAZĂ AI TREMORULUI FIZIOLOGIC LA PROBA ORTOSTATICĂ

Abstract

In young persons the orthostatic test with an initially activated „mechanic-reflex” produced a 1.3 increase of physio-logical tremor spectral energy and a greater density (by 34.1%) of vibrations in the 14-18 Hz frequency range. In elderly persons with an initially activated „mechanic-reflex” component the change in body position was accom- panied by a 1.2 decrease of spectral energy, due to a reduction in the density of vibrations in the 7-13 Hz frequency range (by 29.0%) and in the 14-18 Hz frequency range (by 24.3%).
