Dawn Skelton was involved in a lengthy new Cochrane review update on Exercise to Improve Balance in older people last year. The new update includes 94 research trials and gives useful information for practitioners out there wanting to concentrate on balance improvements (as opposed to falls reduction) in older people.
You can read the full review (if you have a few hours to spare!) or a summary of the review here.
There is a podcast by the first author, Professor Tracey Howe, that you can view here.
