Electrical Bioimpedance cerebral monitoring. Preliminary results from measurements on stroke patients

Electrical Bioimpedance Spectroscopy (EBIS) is currently used in different tissue characterization applications. In this work we aim to use EBIS to study changes in electrical properties of the cerebral tissues after an incident of hemorrhage/ischemic stroke. To do so a case-control study was conducted using six controls and three stroke cases. The preliminary results of this study show that by using Cole-based analysis on EBIS measurements and analyzing the Cole parameters R₀ and R_∞, it is possible to detect changes on electrical properties of cerebral tissue after stroke.
