Insoles That Buzz Your Feet Could Improve Balance

Insoles that electrically stimulate the feet with random vibrations that are too gentle to feel can affect a person's stride, and may boost stability, offering a potential new way to decrease the risk of falls and injury from balance loss, a new study finds. Study participants undergoing strenuous activity while wearing such insoles adjusted their strides in a way that typically improves balance, the research found. The insoles work using a process called "stochastic resonance" (SR), a method fo
