Abstract

The disclosed principles provide wearable body sensor systems and related methods to evaluate the whole body movement with or without an assistive walking device. More specifically, the disclosed principles monitor the whole body movement including COG & BOS with a 3-dimensional (3D) mapping over a given period of time. The disclosed principles provide a number of objectives, which include providing a wearable body 3D sensor network that can constantly monitor change of COG over the BOS during daily mobility; to clinically evaluate older adults in maintaining upright posture and prevent falls in senior living communities; and to clinically establish a quantitative mathematical model to determine the stability of the older adults.

Claims30

Dependent claims

A system for evaluating movement of a human body, the system comprising:

a central sensor node positioned substantially at the center of gravity of the body;
a network of sensors dispersed about predetermined locations on the body and configured to gather data regarding positions of the predetermined locations during movement of the body's center of gravity with respect to the body's base of support;
a computing device configured to receive sensor data from the central sensor node and the network of sensors, and based on the received data:
detect balance deficiencies of the body based on positions of the body's center of gravity in relation to corresponding positions of the body's base of support during movement of the body, and
evaluate the gathered data to determine unfavorable positions of one or more of the predetermined locations during detected balance deficiencies;
and
a feedback device configured to provide feedback when one or more of the predetermined locations of the body moves into one or more corresponding unfavorable positions.
