IT may not look like rigorous exercise, but the Chinese martial art of t'ai chi can help keep the elderly on their feet, researchers revealed today.

A new review of studies found the practice, characterised by gentle sweeping movements, helped prevent falls and improved mental wellbeing among older people. However, the authors said it did not appear to help relieve the symptoms of cancer or rheumatoid arthritis.

Several projects have examined the impact of t’ai chi on a range of conditions but their findings have been contradictory.

Researchers from the Korea Institute of Oriental Medicine in South Korea and Exeter University decided to compare the conclusions of the reviews to gain a better understanding of the benefits.

Some 35 reviews assessing t’ai chi were identified from English, Chinese and Korean databases. They looked at the effectiveness of the technique in a variety of disease areas, including cancer, Parkinson’s disease, high blood pressure and type 2 diabetes. Some projects assessed the benefits of t’ai chi for psychological health, balance and fall prevention.

The research team said it was relatively clear that classes helped older people avoid stumbles and was good for frame of mind.
