Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Center of pressure (COP) excursion is often used to quantify the stability of standing balance in clinical and experiments, but in fact, the stand balance is determined by maintaining the center of mass (COM) of body within the base of support. As ankle fixation will change the mechanism of keeping standing balance, the relationship between COP and COM may also be changed. On the purpose of discussing whether COP can still be used to assess the stability of standing balance with ankle fixed, this study employed a method for simultaneous measurement of COP and COM to acquire 10 subjects´ standing balance data. Then we analyzed the difference between COP and COM during standing with or without ankles fixation. We found there are some differences and the correlation between COP and COM decreased. Therefore, we suggest these differences should be considered when COP is used to quantify the balance stability of postures with ankle fixation.
