Dopamine's main job in the body is to control the cells which manage motor function.

Since there is not enough dopamine in the body, the nerves are constantly out of control, sending more then twice as many electrical signals to the muscles and limbs. Because of this, the muscles, especially in the hands and feet, are constantly trembling. The tremors start out very faint, referred to as "pill rolling tremors".
