Research Abstract	A three-dimensional motion analysis system is not used in clinical setting. One of the reasons is a problem of the utilities of the indexes. As a result of this study, we were able to make a healthy subject model using Lissajous' figure. A purpose of this study is to develop the method of the treadmill gait analysis using the Lissajous' figure. Also, it was found that we could determine an abnormal gait by a shape of the Lissajous' figure and a relative position of multiple Lissajous' figure. Furthermore, we were able to analyze an abnormal gait quantitatively. Furthermore, we were able to analyze an abnormal gait quantitatively.
