    Finger tremor was measured in six normal subjects during intravenous infusions of adrenaline (10 ngkg-1min-1 and 50 ngkg-1min-1) resulting in venous plasma adrenaline concentrations within the physiological range (0.77 +/- 0.08 and 2.28 +/- 0.18 nmoll-1). Tremor amplitude significantly increased after 15 and 25 minutes infusion at the higher dose of adrenaline. The lower dose of adrenaline increased tremor in three of the six subjects.
