Motion Monitoring and Analysis System
First Claim
1. A system for monitoring motion of a subject, the system comprising:
- a plurality of sensor elements mounted to movable body segments of a subject, said sensor elements capable of sensing parameters associated with individual movement of the body segments;
at least one control device for receiving said sensing parameters from said sensor elements and combining said sensing parameters to determine overall motion of said movable body segments; and
an analysis means for analysing said overall motion of said movable body segments to determine whether said overall motion of said movable body segments is within acceptable limits.

Abstract
A motion analysis system (10) in which sensor elements (20) attached to movable body segments record movement parameters including angular velocity and acceleration. A control device (40) receives the movement parameters and determines an overall motion of the movable body segments. The overall motion is analysed against an acceptable motion model to determine whether the overall motion is within acceptable limits. The sensor elements (20) and control device (40) are lightweight and can be worn during normal movement activities thereby allowing monitoring of work-based activities, such as lifting or typing. The invention is useful for detecting and correcting problems leading to lower back disorders and repetitive strain injuries.
