ACL Injuries … more than a knee
In this podcast: Adam Lepley joins Amy & JJ to talk about his research.
From the University of Michigan:
ANN ARBOR—It’s known that some joint function is often permanently lost after anterior cruciate ligament reconstruction, and re-injury is common even with intensive physical therapy, but it’s unclear why.
New research from the University of Michigan School of Kinesiology shows structural changes in the brains of patients who underwent ACL reconstruction. These changes hinder recovery and may contribute to performance deficits and re-injury, says study co-author Lindsey Lepley, U-M assistant professor of athletic training.
Lindsey Lepley and colleague Adam Lepley, clinical assistant professor of athletic training, took MRI brain scans of 10 ACL-reconstructed patients. The scans showed that part of the corticospinal tract—the pathway that scuttles messages from brain to muscles—had atrophied in the patients.
The corticospinal tract runs from front to back through both hemispheres of the brain. The side of the tract that controls the ACL-reconstructed knee was about 15% smaller than on the uninjured side, the researchers say.
