- Abstract
The purpose of this paper is to provide a new method for detection of leg movement using bio-impedance. This impedance is measured by four-electrode method. As the impedance changes resulting from ankle, knee, and hip movements depended heavily on electrode placement, we determined the optimal electrode configuration for those movements by searching for high correlation coefficients, large impedance changes, and minimum interferences in ten subjects. Our optimal electrode configurations showed very strong relationships between the ankle joint angle and ankle impedance(r=−0.913), between the knee joint angle and knee impedance(r=0.944), and between the hip joint angle and hip impedance(r=0.823). This study showed possibility that lower leg movement could be easily measured by impedance measurement system with two pairs of skin-electrodes. [ABSTRACT FROM AUTHOR]
