<p>A posturographic method to investigate the human postural system by calculating interactions between pressure fluctuations over time on four separate portable platforms (Figure 1), each put beneath a subject's heel and tow part respectively. The platforms can be positioned in varying positions, as well as superimposed on a secondary surface (A-H), which in turn can be tilted, rotated, as well as simultaneously tilted and rotated generating spiral motion. Six secondary pressure interaction scores ( between 2 heels and 2 toes, heel and toe of each foot and each heel and its contralateral toes) based on 4 primary parameters (Weight Percentage, Sway, Fourier Spectral Intensities and Fourier Harmony) are computed.</p> |
