Watch Your Step!
When exercising, the force centered on your ankle can exceed up to seven times your body weight. 23,000 people sprain their ankle every day in the United States, resulting in 1.6 million doctor office visits annually. The direct and indirect costs (e.g., lost days from work) associated with treating ankle sprains exceed $1.1 billion annually. To make matters worse, these numbers do not take into account the long-term disability often associated with ankle sprains. Overweight athletes with a prior history of ankle sprain are 19 times more likely to suffer another ankle sprain.
