Explanation:
According to my research on studies conducted by various neurologists, I can say that based on the information provided within the question the doctors will likely find Christy's problem in the Cerebellum which is located in the Hindbrain.

A problem with the Cerebellum can impair movements similar to what Christy is experiencing.
