Finger dyskinesia would lessen when this patient squeezes or grasps another hand. Abnormal movements due to TD occur at rest and lessen or stop with activation or touch.

For example, asking a patient with TD to open his or her mouth usually diminishes orofacial dyskinesia; likewise, tongue protrusion often lessens tongue dyskinesia. Generally, movements associated with TD worsen when attention is detracted from them.
