LARA LAFARGUE, Alcibíades et al. Bioelectrical parameters in vitro and in vivo estimated with analyzers Bodystat^®1500-MDD and BioScan^®98. MEDISAN [online]. 2013, vol.17, n.9, pp.4054-4063. ISSN 1029-3019.

A controlled trial with 2 body electrical impedance commercial analyzers was carried out (Bodystat^® 1500-MDD and BioScan^®98) at the Pediatric Oncology Department of the Southern Children Hospital in Santiago de Cuba, from September to October 2009, for which an in vitro simulation with gauges of each device and an in vivo study in 32 apparently healthy adults and 32 children with different conditions were conducted. Electrical resistance and capacitive reactance were estimated with both analyzers, and impedance module and phase angle were also calculated. The two-means Student's t test for paired samples and the Bland-Altman method were used as statistical criteria. There were not significant differences between the two analyzers by introducing correction factors for electrical resistance and capacitive reactance; therefore, it is possible to use either to characterize bioelectrically apparently healthy individuals and patients with different conditions.
