Background: Quantitative measurement of valproate and lithium induced tremor using hand steadiness tester and their comparison in bipolar disorder. Methods: 200 newly diagnosed patients of bipolar disorder were randomly allocated into two equal groups receiving lithium (300mg twice daily) and sodium valproate (500 mg twice daily) after they fulfilled the inclusion / exclusion criteria of the study. 87 patients from Lithium group and 93 from Valproate completed the study. Hand Tremor was assessed quantitatively at 0, 6, 12, 18 and 24 weeks using hand steadiness tester. Anxiety level of the study subjects was assessed to be insignificant using a standardized anxiety scale. Final data was assessed after 24 weeks by using Stat Calc and Z test.
