Abnormal movements due to TD occur at rest and improve or stop with activation or touch; finger dyskinesia improves in this patient when she squeezes or grasps another hand. Several similar tests may be used during the physical examination when assessing a patient for TD. For example, asking a patient with TD to open their mouth usually diminishes orofacial dyskinesia; likewise, tongue protrusion often lessens tongue dyskinesia.
