A cross-sectional study of influence of cerebral dominance on cardiovascular responses to autonomic stressor tests in adolescents

Amar Arun Barawade, Parwati Patil.

Abstract
Background: Hand preference is perhaps the most obvious behavioral asymmetry observed in humans and is related to cerebral dominance. Animal and human studies have shown that cerebral cortex has a definite role in regulation of cardiovascular autonomic activity. Each hemisphere exhibits differential control over dynamics of heart especially the sympathetic activity is controlled by right hemisphere insula in particular. Hence, the present study was conducted to evaluate influence of cerebral dominance (handedness) on cardiovascular responses such as heart rate (HR) and blood pressure (BP) indices to autonomic stressor tests in the left and right hander adolescents.

Aims and Objectives: The aim of the study was to evaluate the differences in cardiovascular responses in the left and right handers to autonomic stressor tests.

Materials and Methods: The present cross-sectional study was conducted in 35 right and 35 left hander students of age group 16–20 years. Autonomic stressor tests used in the study were handgrip dynamometry and cold pressor test (CPT).

Results: The right and left handers had similar baseline values of BP and HR. All the subjects responded to Autonomic function tests by increased BP and HR from baseline. The absolute BP values and change in BP from baseline were significantly higher in the left than right handers both during and after the tests. HR values showed significant differences in peak values during both the tests. Visual analog score was similar during CPT in both groups.

Conclusion: The HR and BP responses to autonomic stressor tests are higher in the left handers than right handers supports the fact that the right hemisphere has more influence on sympathetic activity of heart.

Key words: Cerebral Dominance; Hand Preference; Autonomic Stressor Test; Handgrip Dynamometry; Cold Pressor Test
