Position Name Description At rest Resting tremors Tremors that are worse at rest include Parkinsonian syndromes and essential tremor if severe. This includes drug-induced tremors from blockers of dopamine receptors such as haloperidol and other antipsychotic drugs. During contraction (e.g. a tight fist while the arm is resting and supported) Contraction tremors Tremors that are worse during supported contraction include essential tremor and also cerebellar and exaggerated physiological tremors such as a hyperadrenergic state or hyperthyroidism. Drugs such as adrenergics, anticholinergics, and xanthines (such as caffeine) can exaggerate physiological tremor. During posture (e.g. with the arms elevated against gravity such as in a 'bird-wing' position) Posture tremors Tremors that are worse with posture against gravity include essential tremor and exaggerated physiological tremors. During intentional movement (e.g. finger-to-nose test) Intention tremors Intention tremors are tremors that are worse during intention, e.g. as the patient's finger approaches a target, including cerebellar disorders. The terminology of "intention" is currently less used, to the profit of "kinetic".
