    Abstract

    For a quantitative EMG analysis reliable and unique values of the electrical conductivities of skeletal muscle tissuein vivo are indispensable. Literature values do not satisfy these criteria. In the paper experimental results of conductivity measurements (four-electrode technique) on musclesin vivo on which quantitative EMG experiments are also carried out are reported. Depending on the interelectrode distance (IED) in the four-electrode technique the results appear to be either frequency dependent (IED=0·5 mm) or frequency independent (IED=3·0 mm). The anisotropy value obtained with an IED of 0·5 mm is frequency dependentin the frequency range of EMG signals. Experimental results of different muscle types (white muscle, EDL rat and red muscle, soleus rat) appear to be significantly different.
