本项目的目的是评估使用一种新的分析技术，分形维数分析，量化的安静的立场中心的压力（COP）。通过使用分形维数分析COP，它可能会获得更多的信息，控制在安静的立场比传统的分析以前允许。目前的项目考虑了一组年轻的健康参与者和一组老年健康参与者比较COP的分形维数分析的COP的传统措施。结果表明，两种类型的分析都能够区分老年组的睁眼和闭眼。然而，分形维数分析更准确地检测到参与者群体之间的差异时，站在他们的眼睛闭上。基于这些结果表明，分形维数分析是更信息的姿态控制比传统的措施。有人建议，分形维数类型的分析可以纳入临床测试，以确定患者的病理。
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.
