Head Injury Outcome Assessment (HIO)
Patients can experience post-concussion symptoms for days, weeks, months or even years. Now that a number of months have passed since your brain concussion, we would like to know which symptoms you are still experiencing and how much they have changed your life. Please choose the correct number below.
1 = I am exactly the same before my injury
2 = I still have mild symptoms or this makes my life a little different than before
3 = I still have moderate symptoms or this makes my life a lot different than before
4 = I still have severe symptoms or this makes my life completely different than before
