Research Finds Brain Changes, Needs to be Retrained After ACL Injury

Researchers at The Ohio State University Wexner Medical Center found that regaining full function after an anterior cruciate ligament (ACL) injury is more that just physical – it requires restraining the brain. A new study shows parts of the brain associated with leg movement lagged during recovery from an ACL injury. Through comparing brain scans, researchers could see the differences in brain activity in healthy adults, versus those recovering from ACL injuries, when extending and flexing the knee. “The brain fundamentally changed in how it processes information from an injured knee,” said Dustin Grooms, a researcher who conducted the study at Ohio State and is currently employed at Ohio University. “We think those changes play a big role in why people who recover from ACL injuries don’t trust their knees entirely and tend to move them differently.” Click here to read more.
