Appendicular skeletal muscle mass: prediction from multiple frequency segmental bioimpedance analysis
Article Abstract:
A study assessing the need for an independent age term in appendicular skeletal muscle prediction models is presented. It is assumed that stature-adjusted impedances at frequencies higher than 50 kHZ are controlled. Measurements of the appendicular segmental impedance in health adults by varying the bioimpedance analysis (BIA) frequency have been undertaken. The mass of the lean tissue compartments have been determined previously by using dual-energy x-ray absorptiometry. Results show that BIA can play an important role in predicting appendicular skeletal muscle mass.

Altered body water distribution in subjects with juvenile rheumatoid arthritis and its effects on the measurement of water compartments from bioelectric impedance
Article Abstract:
Bioelectric impedance analysis for predicting the total body water (TBW) and extracellular water (ECW) gives incorrect results for juvenile rheumatoid arthritis patients (JRA) due to their altered body water distribution. A formula which depends on the ratio of ECW to intracellular water (ICW) is developed using a sample of healthy children. JRA patients have a higher TBW% and ECW:ICW ratio due to chronic inflammation and malnutrition. Population-specific formulae that incorporate these differences in TCW and ECW:ICW give more accurate results for JRA patients.

The prediction of total body water and extracellular water from bioelectric impedance in obese children
Article Abstract:
Bioelectric impedance analysis (BIA) has been recognized as a useful method for the assessment of total body water (TBW) and extracellular water (ECW). Its application in obese children was tested and it was proven to be so. The impedance index, on the other hand, was found to be a useful tool only for the assessment of TBW but, not of ECW among children with varying degrees of fatness.
