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

Figure 4

The maximum displacement of COP in the ML direction as collected in the quiet standing and standing with upper body movement. 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).
