Insoles that electrically stimulate the feet with random vibrations that are too gentle to feeling can affect a person’s stride, and may boost stability, offering a potential new route to lessening the risk of autumns and injury from balance loss, a new study finds.

Study participants undergoing strenuous activity while wearing such insoles adjusted their steps in a way that typically improves balance, the research found. The study was published online in the May 2016 issue of the journal Medicine& Science in Sports& Exercise.

The insoles run use a process called “stochastic resonance”( SR ), a method for amplifying a weak signal by adding “white noise” across a spectrum of frequencies. The vibrations produced by the insoles may be imperceptible, but they offer a type of signal upgrade to the sensitivity of the user’s sole, which translates into enhanced performance while walking.[ 7 Common Exercise Errors and How to Fix Them]

Earlier examines explored how this technique might be used to improve balance in elderly people. It’s not surprising that such studies took place, said Daniel Miranda, the lead author of the new analyze and a Technology Development Fellow at the Wyss Institute at Harvard University in Massachusetts.

“Somebody who’s 65 or 70[ years old] who’s generally healthy may have some sensory deficits due to the natural aging process, ” Miranda told Live Science. It stimulated sense that examines would investigate how this technology could help older people with decreased sensitivity recover some of what they had lost.

But, Miranda and his colleagues wondered, might there also be applications for young person?
