Research of hand tremor vibrations and interference with external mechanical oscillations source

Abstract

This paper presents the research of hand tremor vibrations and interference with external mechanical vibrations source. Photogrammetry were used to capture and analyze hand tremor parameters from 8 patient with essential and Parkinson tremors. Blood perfusion device, that creates mechanical vibrations, was used as an external source of mechanical vibrations and was tested with patients. Device interference with hand tremor showed promising results of hand tremor reduction. The minimum points had 16.5 % lower amplitude of hand tremor. The maximum amplitudes were about 50 % greater and these results show the compatibility of the method but the control algorithm needs to be improved.
