In the clinical application of FES, the traditional evaluation of the electrode failure is difficult and often requires surgical operation, because the electrodes have been percutaneously implanted into the neuromuscular system of the patients. Hence an evakuting method of the condition of the electrodes with non-invasive procedure should be developed, and a useful method with measuring electrical impedance of the electrodes has been reported. Although model circuits in that method can describe the property of the patients' electrodes, parameters (registers and capacitors) in the models have not been discussed quantitatively. Therefore we evaluate the parameters in this paper. We calculate them from impedance data measured from the patients' electrodes (In vivo), and compare them to those measured from in vitro experiments. The result verifies that the parameters, i.e. the models in that method, can characterize the electrode condition.}, pages = {33--40}, title = {電気インピーダンスによる生体内埋め込み電極の状態評価に関する基礎的検討}, volume = {3}, year = {1998} }
