Many investigations have been performed to analyze postural sway. However, few investigators have analyzed the Center of Foot Pressure (CFP) of the individual foot (ICFP). In this paper, our special interest is in the ICFP. In the first study, 85 non-handicapped subjects 20 to 60 years of age took part. They were asked to stand with eyes open and feet parallel, 0cm apart. The relations between foot length and the calculated items were analyzed. There were three different groups with respect to the correlation coefficient and its statistical significance. Strong correlations were determined in mean values of CFP and ICFP to some extent, and weak correlation were determined in those SDs and ranges. No statistical significance was found in the trajectory length. No strong correlation was found with respect to age. In the second study the principal component analysis (PCA) using ICFP was employed to analyze standing sway in both non-handicapped subjects and patients with lower extremity dysfunctions in an integrated manner. In addition to the 85 healthy subjects, 69 patients participated in this study. So a total of 154 data sets were analyzed. Standing posture was identical to that in the previous study. Three principal components (PCOMs) were found to be valuable: magnitude of postural sway, symmetry, and dependence on the sound side. Even though there was no PCOM which could differentiate data with respect to diseases, the three PCOMs clearly illustrated subjects' physical condition in regard to lower extremity functions related to standing ability. The analytical method is expected to be applicable as an auxiliary diagnosis so that any information on conditions which are not apparent from clinical observations can be revealed. We have to find a subjective method to analyze postural sway in each patient because medical rehabilitation procedure must be applied to each individually. The method employed in this research can provide basic knowledge for such purpose.
