Neuroleptic-induced TD is present at rest and diminishes or subsides when the affected body part is activated. For example, squeezing the hand of another person often eliminates finger dyskinesias, tongue protrusion commonly reduces tongue dyskinesias, and mouth opening diminishes orofacial dyskinesias. Simply pointing out these movements and asking the patient to stop can reduce the movements. For example, orofacial movements may be stopped by placing the patient’s fingers on his or her lips.

Neuroleptic-induced TD is increased when the patient’s attention is drawn away from the movements, as when the examiner asks the patient to move a different body part. For example, finger dyskinesias may be increased by asking the patient to walk with arms resting comfortably at the sides. Asking the patient to repeatedly touch the thumb to each finger sequentially in both hands may amplify TD in the tongue and the face. Provocative distracting movements may be necessary to induce movement in mild TD. Distraction is a key component of the AIMS. [46]
