I have ADHD and I have a similar problem. Besides video games and the computer I am in a bowling league, I paint with acrylics, I take swimming lessons and I take drum lessons. See about signing him up for a bowling league, swim team, drums or another instrument, or an art class. I personally suggest that for a 9 year old hyperactive boy he probably would find the most interest in a cartooning or painting or sculpting superheros type art class. If you don't have a pet already consider getting a dog for him to run around at the park with. If another family member's allergies are a problem maybe he could volunteer at a pet store walking the dogs (I know someone who does this) or you could try animal therapy. Another thing you might try is martial arts. I want to try martial arts but I am going to have to wait until I finally get around to applying for and receiving disability money. Also, depending on what video games he's into, there are fictional books written involving various video games so maybe you could use those as an incentive to get him to read! (hopefully) also there's always comic books. I myself am a marvel comics fan. Oh and I've always wanted a trampoline so maybe a trampoline or a backyard climbing apparatus would be something he'd enjoy. You could try a hands-on museum (alot of science museums are hands-on) the only downside is he may have to wait his turn while the other children interact with the exhibits but he is going to eventually have to learn to do that anyway. You could try signing him up for gymnastics...that was fun while it lasted. I hope this helps.
