Abstract

Background: The physiological role of vestibular stimulation is not only confined to maintenance of balance but also in regulation of several body functions such as endocrine, autonomic, and cognitive functions. Vestibular system was reported to reduce the blood pressure with in normal limits by decreasing the sympathetic activity and increasing the parasympathetic activity.

Aims and Objectives: The present study was undertaken to observe the immediate effect of linear vestibular stimulation on blood pressure and pulse rate in healthy females.

Materials and Methods: A total of 15 female students studying 2nd year BDS were part of the study after obtaining the informed consent. The participants acted as self-control. Vestibular stimulation was administered by making the participants to swing on a swing according to their comfort in front to back direction. Blood pressure and pulse rate were recorded from the right hand using JSB digital sphygmomanometer.

Results: There was a significant decrease (P < 0.01) in the pulse rate but remained in normal limits followed by the vestibular stimulation. Both systolic and diastolic blood pressure was reduced and remained in normal limits followed by vestibular stimulation. However, this decrease was not statistically significant.

Conclusion: The study provides further evidence for autonomic modulation of vestibular stimulation. Hence, long-term practice of vestibular stimulation may have beneficial effects on autonomic functions.
