Tai Chi Can Improve Postural Stability as Measured by Resistance to Perturbation Related to Upper Limb Movement among Healthy Older Adults

Figure 6

The 95% confidence ellipse area of COP was collected in the quiet standing and standing with upper body movement tests. The TC group had better postural control than the SE and BW groups when standing with upper body movement. Values are group means ± SE, with “” representing significant differences (where TC group were significantly different from the other groups).
