One of the most common sport injuries are sprained ankles. If you go by the New York Time’s estimation of 8 million sprained ankles per year, you’re best off taking pre-advice on how to fix bad ankles. Just in case.
A growing body of research suggests that many of those second (and often third and fourth) sprains could be avoided with an easy course of treatment. Stand on one leg. Try not to wobble. Hold for a minute. Repeat.
Why should balance training prevent ankle sprains? The reasons are both obvious and quite subtle. Until recently, clinicians thought that ankle sprains were primarily a matter of overstretched, traumatized ligaments. Tape or brace the joint, relieve pressure on the sore tissue, and a person should heal fully, they thought. But that approach ignored the role of the central nervous system, which is intimately tied in to every joint. “There are neural receptors in ligaments,” says Jay Hertel, an associate professor of kinesiology at the University of Virginia and an expert on the ankle. When you damage the ligament, “you damage the neuro-receptors as well. Your brain no longer receives reliable signals” from the ankle about how your ankle and foot are positioned in relation to the ground. Your proprioception — your sense of your body’s position in space — is impaired. You’re less stable and more prone to falling over and re-injuring yourself.
