Abstract

Objective:

Introduction: Reaction time has been defined as the time interval between the application of a stimulus and the response by the subject. Reaction time is defined as interval of time between presentation of stimulus and appearance of appropriate voluntary response in a subject. Our emotions, attention, memories and health conditions these and all added reaction we make are responses to stimuli which play upon us.

Objectives:

Reaction time has well established associations with different clinical situations. In the present paper an attempt was made to correlate the effect of altitude (high & low) on simple reaction time in hypertensive patients.

Design and Method:

An experimental study design was planned.A group 152 hypertensive patients were selected from high altitude region (Deharadun & Mussoorie,Uttrakhand) whereas the same numbers of hypertensive patients were selected from low altitude region (Lucknow district).The minimum sample size was calculated statistically to achieve desired power & confidence interval. The machine “IMCORP Ambala Reaction Time Instrument” is used to measure the simple reaction time (Auditory and Visual both).The data was analyzed by using statistical software SPSS of version 20.0.

Results:

The average simple reaction time (Auditory and Visual) of hypertensive patients in low and high altitude regions were compared to see the effect of altitude in reaction time of hypertensive patients. The mean auditory reaction time of hypertensive patients at low altitude region & high altitude were 258.9 ( ± 51.1) ms &271.3 ( ± 47.2) ms whereas the mean visual reaction time at low altitude region & high altitude were 267.5( ± 65.3) ms & 298.1 ( ± 58.1) ms.

Conclusions:

The independent t-test shows a significant difference (p < 0.05) in the (visual & auditory reaction time) reaction time of hypertensive subjects of low and high altitude region.
