Distribution of Slopes of Harmonics of Gait Power of Persons with and without Brain Damage

Abstract

A gait is one of indicators of health. We reported that the ratio of the step power per the stride power in Fourier transform harmonics of a gait shows a recovery from a damage of total hip replacement operation several years ago. Now we show that there are linear relations between power of harmonics of gait and the frequency in a double logarithmic chart. The slope values of the linear relations are different between groups with brain damage and without it in a double logarithmic chart. Coefficients of correlation were under -0.93. And its statistical significance level was 0.01( =1%).
