Could Increased Seizures In A Child Be Related To Increased Physical Acitivity?

My 4 year client has a history of seazures but I never saw him have one until last fall when he began more physical activity. He now knocks down blocks, pushes a toy car or a ball away. Prior to this he was just a spectator. Could this increased activity be causing the frequent activity? They are facial in nature, eyes either stair straight ahead or blink, upper lit twitches, or his mouth opens and closes. These last aprox 3 seconds each. He can have 7 to 10 an hour. He takes phenobarbital, klonopin. Sees a neurologist and they are trying to figure it out. I noticed the harder he tries to think and lift arms and hands and move them, the seizures started and contenue. He doesn t have many at other times in the day. Could they really be activity induced?? Does that mean he has to quit playing????
