However, the choice of electrode systems sizes is not always properly considered when using the electrical impedance myography method in the existing approaches, which is important in terms of electrical impedance signal expressiveness and reproducibility. The article is devoted to the determination of acceptable sizes for the electrode systems for electrical impedance myography using the Pareto optimality assessment method and the electrical impedance signals formation model of the forearm area, taking into account the change in the electrophysical and geometric parameters of the skin and fat layer and muscle groups when performing actions with a hand. Numerical finite element simulation using anthropometric models of the forearm obtained by volunteers\u2019 MRI 3D reconstructions was performed to determine a sufficient degree of the forearm anatomical features detailing in terms of the measured electrical impedance. For the mathematical description of electrical impedance relationships, a forearm two-layer model, represented by the skin-fat layer and muscles, was reasonably chosen, which adequately describes the change in electrical impedance when performing hand actions. Using this model, for the first time, an approach that can be used to determine the acceptable sizes of electrode systems for different parts of the body individually was proposed.<\/jats:p>","DOI":"10.3390\/s22010097","type":"journal-article","created":{"date-parts":[[2021,12,27]],"date-time":"2021-12-27T01:06:54Z","timestamp":1640567214000},"page":"97","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Determination of the Geometric Parameters of Electrode Systems for Electrical Impedance Myography: A Preliminary Study"],"prefix":"10.3390","volume":"22","author":[{"given":"Andrey","family":"Briko","sequence":"first","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8585-4408","authenticated-orcid":false,"given":"Vladislava","family":"Kapravchuk","sequence":"additional","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6715-7668","authenticated-orcid":false,"given":"Alexander","family":"Kobelev","sequence":"additional","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5989-9044","authenticated-orcid":false,"given":"Alexey","family":"Tikhomirov","sequence":"additional","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4085-3553","authenticated-orcid":false,"given":"Ahmad","family":"Hammoud","sequence":"additional","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]},{"given":"Mugeb","family":"Al-Harosh","sequence":"additional","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6898-6887","authenticated-orcid":false,"given":"Steffen","family":"Leonhardt","sequence":"additional","affiliation":[{"name":"Chair of Medical Information Technology, RWTH Aachen University, 52074 Aachen, Germany"}]},{"given":"Chuong","family":"Ngo","sequence":"additional","affiliation":[{"name":"Chair of Medical Information Technology, RWTH Aachen University, 52074 Aachen, Germany"}]},{"given":"Yury","family":"Gulyaev","sequence":"additional","affiliation":[{"name":"Kotelnikov Institute of Radioengineering and Electronics (IRE) of Russian Academy of Sciences, 125009 Moscow, Russia"}]},{"given":"Sergey","family":"Shchukin","sequence":"additional","affiliation":[{"name":"Department of Medical and Technical Information Technology, Bauman Moscow State Technical University, 105005 Moscow, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kobelev, A.V., and Shchukin, S.I.
