The purpose of this study is to verify the gait measurement function of the knee sleeve equipped with an IMU(Inertial Measurement Unit) sensor based on ICBM(IoT, Cloud, Big data, and Mobile) and to verify the effect of wearing and not wearing the knee sleeve to provide basic data on the development of the knee sleeve based on ICBM which can analyze gait pattern and improve gait ability. The measurement accuracy of the IMU sensor was verified by comparing the accelerations measured by the IMU sensor attached t o the knee s leeve and the 3D M otion C apture S ystem while g ait measuring in 2 0 elderly persons over 60 years old. Also 16 subjects, age of 20’s, and 15 subjects, age of 60’s, were analyzed for the effect of wearing and not wearing the knee sleeve for blood lactate, blood glucose, steps, gait tempo, and heart rate when walking. The results of this study are as follows.
As a result of comparing the difference between the acceleration values measured by the IMU sensor attached to the knee sleeve and the acceleration values of the mass center of IMU sensor calculated by the motion analysis with RMSE(Root Mean Squared Error), the RMSE on the x-axis is 1.154, the RMSE on the y-axis is 5.765, and the RMSE on the z-axis is 2.145.
Correlation analysis of the acceleration values of the mass center of IMU sensor(MCI) calculated by the motion analysis, the acceleration values measured by the IMU sensor(IMU), and the acceleration value of knee center(KNE) calculated by the motion analysis showed that MCI and IMU showed no significant correlation between the x-axis and the y-axis, indicating a significant correlation in the z-axis. IMU and KNE did not show a significant correlation on the x-axis and the z-axis, but a significant correlation on the y-axis.
