- Electrodermal activity in relation to diabetes, autonomic neuropathy and aging: a preliminary study Luis Bolanos Jose María Vicente Oscar Andrés Vivas José María Sabater-Navarro Ingeniería diabetes autonomic neuropathy Electrodermal activity galvanic skin response A reduced electrodermal activity (EDA) may be related to autonomic neuropathy (AN). The aims of this study were to independently study the characteristics of the EDA and its correlation with diabetes and AN. During a self-designed test, mean skin conductance level (M-SCL), mean skin conductance response (M-SCR) to stimuli, and difference in M-SCL between feet (DBF) were obtained through a model-based decomposition based on Bayesian statistics and mathematical convex optimization. A group of 22 subjects were included for the final test. Diabetic patients were stratified based on their clinical history and care habits, dividing them into those out of risk and those at risk of developing AN. Statistical difference was found for the latter regarding M-SCR (p < 0,01) and DBF (p < 0,05) with respect to the control group. While past research failed to address potential sources of interference with the EDA measurement, namely emotional state, degree of concentration on the task, and body posture, this study proposes a well-defined protocol to stimulate subjects and acquire proper and reliable EDA data. 2019 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379859004 https://www.redalyc.org/journal/643/64379859004/ https://www.redalyc.org/journal/643/64379859004/html/ https://www.redalyc.org/journal/643/64379859004/64379859004.epub https://www.redalyc.org/journal/643/64379859004/movil 10.15446/ing.investig.v39n3.74982 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.39
