Abstract

The object of this study is to determine the accuracy of our new compliance meter system of the soft tissues. This meter was composed of a strain gauge, a linear gauge and a controllable adaptor of three dimension. The voltage of the strain gauge was measured at balanced with 100 g intervals from 100 g to 2,000 g and then calculated the correlation between the voltage and the weight. And the effects on inclining the pellotte at five and ten degrees from vertical line was examined. The compliance of the sponge block, forearm and anterior part of the lower leg was measured respectively by this meter. The compliance was indicated by the voltage of the gauge when the pellotte was pressed down by 5, 10, 15, 20mm depth on the materials. <br>The results were as follows: <br>(1) The regression line of the correlation between the weight and the voltage of the strain gauge was V(v)=0.0031F(g)-0.0098, and its coefficient was 0.9998. <br>(2) The force at five degrees inclination was not significantly different from the force at zero degree, but at ten degrees it was significantly different. <br>(3) The values of the compliance of the forearm were variable by different days and times. <br>(4) Values of the compliance of the anterior part of the lower leg were constant even on different times.
