METHOD AND DEVICE FOR MONITORING POSTURAL AND MOVEMENT BALANCE FOR FALL PREVENTION
First Claim
1. A method for monitoring postural and movement balance for fall prevention, comprising:
- obtaining a plurality of sensing signals of a human body;
modeling related kinematics of a center of mass (COM) signal and a center of pressure (COP) signal according to the sensing signals;
calculating a correlation coefficient according to a mediolateral velocity of the COM signal and the COP signal;
obtaining a threshold according to at least one regression model stored in a database;
determining whether the correlation coefficient is smaller than the threshold;
outputting an alarm when the correlation coefficient is smaller than the threshold.

Abstract
A method for monitoring postural and movement balance for fall prevent is provided. The method includes the following steps. Multiple sensing signals of a human body are obtained. A center of mass (COM) signal and a center of pressure (COP) signal are modeling according to the sensing signals. A correlation coefficient is calculated according to a mediolateral velocity of the COM signal and the COP signal. A threshold is obtained according to at least one regression model stored in a database. Whether the correlation coefficient is smaller than the threshold is determined. An alert is produced when the correlation coefficient is smaller than the threshold.
