Fractal dimension analysis of anterior/posterior centre of pressure significantly increased in elderly participants when standing with eyes closed compared to eyes open (1.58 vs 1.51, p<0.05).

Does fractal dimension analysis of centre of pressure improve discrimination between elderly and young individuals compared to traditional measures?
Fractal dimension analysis of centre of pressure may be more informative about posture control than traditional measures and could help identify patients with balance pathologies.

The aim of this project was to evaluate the use of a new analysis technique, fractal dimension analysis, for quantification of quiet stance centre of pressure (COP). By using a fractal dimension analysis of COP, it might be possible to gain more information about control during quiet stance than traditional analyses have previously allowed. The current project considered a group of young healthy participants and a group of elderly healthy participants to compare traditional measures of COP against a fractal dimension analysis of COP. Results indicated that both types of analyses are able to distinguish between eyes open and eyes closed in the elderly group. However, the fractal dimension analysis more accurately detected differences between the participant groups when standing with their eyes closed. Based on these results it is suggested that fractal dimension analysis is more informative about posture control than traditional measures. It is suggested that a fractal dimension type of analysis can be incorporated into clinical testing to identify patients with pathologies.
Doyle et al. (Thu,) conducted a cross-sectional in Healthy adults (n=91). Eyes closed during quiet stance vs. Eyes open during quiet stance was evaluated on Fractal dimension of anterior/posterior centre of pressure in elderly participants (p=<0.05). Fractal dimension analysis of anterior/posterior centre of pressure significantly increased in elderly participants when standing with eyes closed compared to eyes open (1.58 vs 1.51, p<0.05).
