GAIT ANALYSIS USING AN INERTIAL SENSOR

Henry Boger

Abstract


It is time to find the answers to how to help in the prevention of falls. By working with a person’s gait and discovering what happens to the roll, pitch, and yaw as a person walks we can begin to develop skills to use in rehabilitation so that an individual can walk more safely; skills that can correct the roll, pitch and yaw when a deviation is found that causes difficulty when walking. What we see here in this paper is only the beginning.

 

The first aim is to establish a standardized method for stability testing. A second aim is to determine a method of analysis of the recorded data.

 

A series of tests were conducted for the benefit of residents of a retirement community. The long term goal is to aid in fall prevention.

 

An inertial sensor was used to obtain real time data during the tests, and these data were recorded and saved for later evaluation.
