Prediction of Factors of Pincer Nail using Gravity Center Fluctuation based on Factor Analysis

Abstract

A pincer nail is a disease of the form of the nail, it is difficult for a patient with a serious pincer nail to walk. There are a lot of opinions in the cause of the pincer nail, however the cause is not clear. Some of the medical doctor guess that one of the cause is the gait motion from the implicit knowledge. The implicit knowledge is useful and important, however it is not expressed by the sentence and figure. This paper proposes the method for prediction of the attention point in gait motion using the factor analysis. Three attention points are obtained by the result of factor analysis. It is clear that two attention point among three are corresponding with the previous studies. We recheck the movie, since the rest of the attention point is considered. The rest of the attention point is the new unique gait motion that we have not noticed. As a result, the result of the factor analysis is useful to extract and guess the factor of the unknown factor.
