Figure 1. Exemplar respiration and anterioposterior center of pressure data during eyes open standing before and after Tai Chi training.

Figure 1

Determination of respiration and anterior-posterior center of pressure dynamics were simultaneously recorded over time and compared. Ensemble Empirical Mode Decomposition (EEMD) was used to decompose each signal into oscillatory modes, each representing the frequency modulation of the signal at a specific frequency range. The raw data prior to EEMD are shown before (A) and after (C) Tai Chi. (B) Shows the decomposed respiratory and center of pressure modes of an 89 year old male before the Tai Chi intervention. The dark black line represents respiration and the light grey line shows center of pressure. After Tai Chi (D) there was less synchronization between respiration and center of pressure for this participant.
