Identification of changes in mechanical properties of human axial system due to stress and relaxation regime

Popis výsledku v původním jazyce

The aim of this work was to verify the applicability of the TVS (Transfer Vibration through Spine) methodology for registration of changes in viscoelastic characteristics of the axial system. The detection method consists in applying γ pulse pulses with a half-width of 5ms and then a harmonic excitation of continuously varying from 5Hz to 160Hz on vertebrae C7 and L5. This ripple is transmitted along the axial system and acceleration of all the spinous processes of the vertebrae is sensed by accelerometer sensors to propagate the wave between C7 and S1. On the basis of measured data (input excitation and its sensed response on spinous processes), the change of total viscoelastic parameters of the spine was evaluated before and after monotonous or other spinal strain or before and after relaxation. Existing results confirmed the TVS method is suitable for detection of mechanical changes of the axial system. It was proven transmission of ripples through the axial system of a person also changes by the influence of alternations created by monotonous or physical strain or conversely relaxation. (C) 2019.
