| Outline of Final Research Achievements |
The feasibility of 4-terminal-method-measurement of electrical impedance over a wide frequency range using measurement devices used in the electrochemical field was investigated using a test circuit created by combining a capacitor and a resistive element. The results suggested that reasonable measurements can be performed in the frequency-range from 0.1 Hz to 1 MHz with one of the electrochemical measurement devices. Using the device, we also measured the impedance of skeletal muscle models made with straws and dialysis hollow fiber modules, and compared the measured and theoretical values to evaluate the performance of the device.

本研究の目的は、理学療法学の分野で重要な骨格筋の緊張度の評価を、電気インピーダンス計測によって非侵襲的かつ客観的に行う技術の開発である。我々が独自開発した技法による理論計算から、これまで報告例のない1 Hz付近という低周波数での情報が緊張度評価法の構築に有用であることが示唆されていた。本研究では、これまで使用例のない電気化学用装置を用いることを提案し、試験回路や骨格筋模型を測定し、実測値と理論値を比較することによって計測装置の妥当性を評価できた。
