Abstract

[Purpose] To simplify the method of analysis of phase synchronization between cardiac and locomotor rhythms, we introduce a method of analysis using Microsoft Office Excel. [Methods] We use the data of a healthy man during walking as an example. Two time-series data are generated from the R wave onset time signals of the ECG data and the heel contact signals of the foot switch data. We calculated the relative phase between the two time-series data. Next we generated a scatter diagram which shows the time-line as the abscissa and the relative phase as the ordinate (Phase Synchrogram). We also generated a histogram of the relative phase divided into 10 classes. We additionally calculated the strength of synchronization. Lastly to rejectd the hypothesis that the phase synchronization occurs by chance, we analyze the relative phase data using the surrogate data technique. [Conclusion] The software which most physical therapist can use was ubilized to investigate synchronization among biological rhythms in the physical therapy field.<br>
