Analysis of Aging Effect on Human Walking Gait Using Detrended Fluctuation Analysis Technique

  Movement of center of gravity of the human body plays a crucial part in the stability of the human walking. In this paper, we have investigated the effect of aging on the acceleration of center of gravity using a portable 3D acceleration measurement system. Acceleration of the center of gravity data of young and elderly subjects is analyzed during normal walking using detrended fluctuation analysis technique. It was observed that the scaling exponents of elderly subjects in short term region are less than young subjects. It shows that walking of elderly subjects is less correlated in the short-term region putting them on more risk of falls.
