BOONE, N.C. — If you’ve sprained your ankle once, it’s likely it has or will happen again.
According to Appalachian State University’s Dr. Alan Needle, research shows between 50% and 70% of people who have suffered an ankle sprain — the most common injury seen in active people — will suffer another.
Needle, an associate professor in the Department of Health and Exercise Science (HES), has received $57,349 in grant funding from the National Athletic Trainers’ Association (NATA) Research and Education Foundation for research that might alter that trend.
One of the reasons individuals continue to “roll” their ankles during activity, Needle said, is changes in how, post an initial sprain, the brain and nervous system adapt to plan and execute movement. “These changes cause individuals to move in a way that makes them more likely to injure themselves,” he said.
In order to prevent these repetitive injuries, Needle and his research team are proposing methods to address the altered brain and nervous system’s way of coordinating movement using common rehabilitative balancing and agility exercises — while transmitting a low-level electrical current through the brain.

By running this current through either the part of the brain that executes movement or through the part of the brain that plans movement, Needle said he hopes to determine if either is better at improving function for patients with repeated ankle sprains over the course of a four-week rehabilitation regimen.
The project, titled “How to TRAIN Pathways: Targeted Rehabilitation of Ankle Instability through Neurological Pathways,” began in May and will continue through August 2024.
