Flickering glasses may help volleyball players with wobbly ankles

This study tested whether wearing stroboscopic glasses (which flicker between clear and dark) during balance exercises can help female volleyball players with chronic ankle instability. Twenty-four professional players completed a supervised balance training program while wearing the glasses. The researchers measured improvements in balance, jumping, and ankle function. The goal is to find a simple, non-drug way to strengthen ankle stability and prevent future sprains.
