About

To determine the relationship between the effects of different frequencies and duration of Tai Chi Chuan in dose parameters to improve cognitive function in elderly persons with mild cognitive impairment.

Full description

Mild cognitive impairment (MCI) is regarded as a prodrome to dementia and affects 16% to 20% of people aged older than 65 years. Tai Chi Chuan is an increasingly popular multi-modal physical and mental exercise. Studies have shown that Tai Chi Chuan can effectively improve the cognitive function of elderly persons with MCI. However, the relationship between the effects of different frequencies and duration of Tai Chi Chuan to improve the cognitive function of elderly persons with MCI is not yet clear. The purpose of this study is to determine the optimal frequency and duration of Tai Chi Chuan. The investigators will conduct a single-blind, randomized controlled trial in 350 persons who meet the presence of MCI without dementia. Persons will be randomly assigned to either the Tai Chi Chuan intervention group once or twice a week for 12 or 24 weeks, or the health education control group once every four weeks for 24 weeks. All groups will be followed for 52 weeks.
