BOONE, N.C. — Research conducted by Amelia Bruce ’19 while a graduate student at Appalachian State University suggests ankle injuries can be better treated by targeting the brain. The results of this groundbreaking study have been published in the February issue of Medicine and Science in Sports and Exercise, the official journal of the American College of Sports Medicine.
Bruce, who is from Taylorsville, earned an M.S. in exercise science from Appalachian and is currently pursuing her Ph.D. in kinesiology at the University of Virginia.
While at Appalachian, Bruce worked with Dr. Alan Needle, associate professor in the Beaver College of Health Sciences’ Department of Health and Exercise Science. Needle’s previous research had shown the brains of people with ankle instability need more brain activation to do simple tasks. Bruce took the lead with the next step, testing the impact of brain stimulation in treating ligamentous injuries.
Highlights of the study:
- Four weeks of ankle strengthening therapy was performed for 26 study participants. Half received an electrical current through their brain during sessions, while the other half received a placebo current.
- Strength training paired with the electrical current improved the way participants’ brains connected to the ankle muscles, resulting in better balance, muscle activation and perceived function.
- This study was the first to show using treatments that target the brain improves neural function in patients with injuries, and improving neural function amounts to better ankle function and perceived outcomes.
“This topic was of importance to me because injuries in ligaments happen every day. If this intervention worked, it could reshape how clinicians treat these types of injuries during the rehabilitation phase,” Bruce said.
“While clinicians primarily treat the musculoskeletal side (during the rehabilitation phase), there is a whole neural system that is impacted by these injuries and needs just as much attention during treatment,” she added.
When a sprain occurs in ankle ligaments, the brain directs the body to compensate by changing the patient’s gait, Bruce explained. This subconscious compensation causes a weakness in the ankle that leads to recurrent sprains over a patient’s lifetime — potentially leading to inactivity and related obesity, cardiovascular disease and other health problems.
“We want to nip that in the bud before it gets to that point by changing the way the brain reacts to the injury,” Bruce said.
Bruce presented her research findings at several conferences, including the following:
- Appalachian’s 2019 Annual Celebration of Student Research and Creative Endeavors, sponsored by the Office of Student Research, in which Bruce was one of three graduate student winners in the event’s Student Poster Competition.
- The 2019 Human Movement Science Research Symposium held at the University of North Carolina at Chapel Hill.
- The 2019 National Athletic Trainers’ Association Convention in Las Vegas.
- The 2019 International Ankle Symposium in Amsterdam, sponsored by the International Ankle Consortium.
- The 2019 International Symposium on Regenerative Rehabilitation in Charlottesville, Virginia.
Bruce plans to continue her research at the University of Virginia by testing patients with knee ligament injuries.
