Chinese and American investigators have found evidence that tai chi can help older women improve their cognition and postural control, specifically while dual tasking. Thirty-one older women were randomised to tai chi (three sessions per week) or a control group (general interest classes) for 16 weeks. Balance was tested in single leg stance after stepping down from a step, with and without a concurrent auditory response task. Tai chi subjects made fewer errors in the auditory test under dual-task conditions after tai chi training. They also showed significant improvements in their balance after training, in both single- and dual-task conditions. Subjects in the control group did not show any significant improvement in the dual-task condition after the intervention.
