Sport related concussion (SRC) impairs numerous functions of the CNS.
Traditional research has focused on risk of repeat concussion following clearance and return to sport
Several studies have shown a consistent elevated risk of lower extremity injuries from 90 days up to one year following SRC.
These include lateral ankle sprains and ACL injuries. Risk ranges, 1.3-3.4x.
This risk may be greater in those with multiple concussions.
This elevated rate has been seen in populations ranging from high school, college to professional athletes and has also been seen in the general population.
Persistent neurological deficits in cognitive and postural control, stability and gait deviations have been postulated as potential mechanisms.
These may be potential modifiable risk factors before return to play/activity. This may be a role best served by sport physical therapists to assist with sport specific rehabilitation post concussion.
