Cerebellum Ataxia

I had a trafic accident in 2002. This accident makes brain damage, slurring of speech (still), disorder of muscles(especially on movement), ascend stairs, etc... Last've got a doctor who is a norologist,  told me that my cerebellum had a damage in the accident. As you know cerebellum is chief of the human body. I'm triying to manage my movements as posisible as I can. My right side is limited becase of the accident. But not all the part the of right side olso in the movement. My movements are slow. But in the past I was a licenced basketball player.As you know, this sport needs human to be quik movement as posible as human he/she can. But still I cant!
