forcible, uncontrollable movements. These are also usually noticed in the arms, legs, or face.

slow motion.
emotional or personality problems, such as depression,
inappropriate behavior, or paranoia

flex or use the muscle.

The movement has a certain rhythm and speed to it and is usually noticed in an arm or leg. Tremors usually occur when the
person is sitting still and go away with movement.
