Review on improving balance in older people.
A recent Cochrane review studied the outcome of trials to determine the effectiveness of a range of exercise and activity programmes in preventing falls in older people.
The conclusions were that effective programmes ran three times a week for three months and involved dynamic exercises in standing. There is now a category for 3D exrercise with movements in three planes such as Tai Chi. There was weak evidence that some exercise types are moderately effective immediately post-intervention, but no evidence for long-term benefit.
