Abstract

Previously, we reported that in a sample of 14 healthy persons the analysis of the slow movement of the forefinger against a predetermined force presented a behavior that qualitatively is present in all subjects and it is characterized by three parameters: 1) a positive pulsating phase pattern of velocity; 2) pulses of low amplitude are more frequent; 3) a spectral pattern with a frequencies distributed in a wide interval. Now we report the value of physical work developed by the forefinger by unitary distance. We determine the fractal dimension of the velocity time series using the Higuchi method, and the multifractal analysis of the movement pattern. On the other hand, applying these methods to a person with nervous system pathology we find that its movement pattern is clearly different compared with that of a normal person. © 2006 American Institute of Physics.
