The electrical conductivity of skeletal muscle tissue. Experimental results of different muscles in vivo

Estimation of abdominal fat compartments by bioelectrical impedance: the validity of the ViScan measurement system in comparison with MRI

“…Reliable prediction of IAAT using transimpedance would depend on the depth of the IAAT as well as the relative volumes, depths and conductance of other abdominal tissues (for example, muscle, mesentery, spine, liver and other internal organs), all of which are difficult to quantify and correct for. For example, it is the likely that much of the current flux is through superficial muscle, the conductance of which is dependant on muscle fibre direction relative to injection point, as well as presence of lipid within the muscle (Gielen et al, 1984). The observed weaker relationship between MRI and ViScan in those with high liver fat also suggests an influence of organ mass/ composition as higher liver fat is closely associated with increased liver volume (Thomas et al, 2005).…”

Model of electrical conductivity of skeletal muscle based on tissue structure

“…6 the effect of changing the interelectrode distance from 0.05 cm, used in our experiments (GIELEN et al, 1984), to a value of the same order of magnitude as the interelectrode distance mentioned by RUSH et al (1963) (> 0'5cm) is illustrated. The values are calculated for a situation comparable with the four-electrode method, but with infinite large current electrodes.…”

“…Usually, however, measurements of conductivity are based on the four-electrode method: a potential difference caused by current injection by two point-shaped electrodes is measured. Despite the conceptual differences between the model presented and the experimental situation in which conductivity data are usually obtained (GIELEN et al, 1984), there is a good agreement between computed and measured effective electrical conductivities. It is as yet uncertain if this agreement allows the conclusion that the shape of the current electrodes has little influence on the conductivity values.…”
