Summary:
It is difficult to distinguish between the electrogastrograms (EGGs) of healthy elderly individuals and elderly patients by using spectral analysis. The purpose of this study was to determine the feasibility of applying a complex dynamic analysis method to the EGGs of healthy young and healthy elderly male individuals. We analyzed EGGs by using the Double?Wayland algorithm, which is one of the indices of the stochastic characteristics of time series. For most of the temporal intervals, there were significant differences between translation errors estimated from the EGGs of the young and elderly individuals.
