Abstract
A system for monitoring a user that includes a sensor unit configured and arranged to be disposed on the user, the sensor unit including an accelerometer and a communication arrangement; and at least one processor configured and arranged for performing actions including: receiving signals from the accelerometer of the sensor unit; determining a step count from the signals; determining a gait velocity from the signals; determining a step distance from the signals; determining a posture of the user from the signals; and determining a gait posture index as a function of the step count, gait velocity, step distance, and posture. In other embodiments, the system can be used to determine metrics other than the gait posture index, such as a fall prediction score based on gait velocity and posture deviation.
