text: The following phenomena suggest a psychogenic aetiology: (1) sudden onset of tremor, which may present as an emergency or go into remission or both; (2) unusual clinical combinations of rest and postural/intention tremors; (3) decrease in tremor amplitude on distraction or changes in tremor frequency during voluntary movements of the contralateral hand; (4) the presence of the co-activation sign of psychogenic tremor, in which resistance to passive movement about a joint causes the appearance and disappearance of tremor to mirror changes in tone; (5) a clear past medical history of a somatisation disorder and the appearance of additional and unrelated neurological signs with tremor.
