Noninvasive dynamic analysis system and method of use thereof
First Claim
1. A noninvasive dynamic analysis system for measuring and analyzing the motion of the joint of the human body, the analysis system comprising:
- an electromagnetic sensor for noninvasively measuring the positions and the orientations of two sites of the human body opposite each other in relation to the joint and during the motion of the joint;
an electromagnetic measuring device for determining the positions and the orientations of the two sites based on information from the electromagnetic sensor;
a processing device for calculating the degrees-of-freedom of the joint, based on the positions and the orientations of the two sites determined by the electromagnetic measuring device and the position of an anatomic reference point around the joint.

Abstract
A noninvasive dynamic analysis system is provided, in which a measured and analyzed result in a manual test may be fed back to an examiner, in real-time, to allow quantitative and dynamic evaluation of the result. The noninvasive dynamic analysis system includes a transmitter for transmitting an electromagnetic wave or an electromagnetic signal, two receivers fixed to the thigh and the cruris of the human body and capable of receiving the electromagnetic wave transmitted by the transmitter, an electromagnetic measuring device for determining the positions and the orientations of the two receivers based on information from the receivers, and a processing device, such as a personal computer, for calculating and indicating 6 DOF of the knee joint, based on the positions and the orientations of the two receivers, from the electromagnetic measuring device. The two receivers may be fixed to the thigh and the cruris by using two braces.
