Abstract
As a result of multiple regression analysis of the left and right hands of healthy subjects, almost no correlation was found between risk rates of 1% or 5% and either the simple or partial correlative lines. It was determined that the four variables of both the right and left hands were virtually independent variables.
In order to make a comparison with the normal side of hemiplegics, it was necessary to select either the right or left hand of healthy subjects. After examining the coefficients of correlation both hands, the left hand was chosen. From the results of discriminant analysis of the left hand of healthy subjects and the normal side of hemiplegics, it was determined that the discriminant function equation can be expressed as follows as a function of the S-S interval, S-P period, S-C period and the Dh/Ch%.
Z=(2.330 E-05)*S-St+(-5.329 E-02)*S-Pt+(-5.151 E-03)*S-Ct+(1.339 E-02)*Dh/Ch%+6.947
The discriminant boundary value between healthy and hemiplegic patients was 0.391.
