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. Generally, movements associated with TD worsen when attention is detracted from them.
TD is not associated with sensory loss, and hypersensitivity to pain would be unusual.
