A concussion is a traumatic brain injury (TBI) caused by a bump, blow or jolt to the head that keeps your brain from working normally. 

Concussions may also occur from a blow to the body that causes the head to move rapidly back and forth and can occur with or without a loss of consciousness.

Terms generally used in reference to concussions are “knocked out,” “ding,” “got your bell rung,” “seeing stars,” “dazed,” and “head injury” to name just a few. Many concussions that require emergency treatment are because of falls, vehicle accidents and sports injuries.

Children, young adults and older adults are at a greater risk for concussions and may take longer to recover. People who have had concussions before are more likely to have them again.

It is important to seek medical help if you think you have experienced a concussion as delaying necessary treatment could lead to serious complications and even death.

Symptoms may start immediately, however, some may start weeks or months after the concussion.


The OSF Rehabilitation therapists are specially trained to diagnosis and treat concussions.

The therapists may take a health history, do a physical exam and repeat the same questions and tests to gauge your progress. In some cases, additional testing may be needed.

Your treatment may include limiting cognitive and physical activity as well as stress.

For high school athletes, this may include limitations on return to school or work for a period of time.
