DrLudicrous writes "The NYTimes (free registration) is running an article that summerizes a forthcoming Physical Review Letters article. The article is about how low amplitude vibrations can help a person better sense when they are off balance. The authors write that they improved the balance of senior citizens by using small vibrations in the floor, making their sense of balance like that of a 25 year old. Apparently, this background noise helps to stimulate the neurons in the feet, making them more susceptible to detecting imbalances."
