Evaluation of Reaction Time with Variations in Levels of Alertness in Geriatric Population: An Observational Study

Abstract

INTRODUCTION: Reaction time is fastest with an intermediate level of alertness and deteriorates when the subject is either too relaxed or too tense but as we age, our brain connections slow down, slowing up the reaction time. Hence the need arises to synchronize the physiotherapy interventions with the highest level of alertness with lesser reaction time for better outcome. Aim and objective: To evaluate the reaction time with variations in the level of alertness in geriatric population. METHODS AND MATERIAL: This single group observational study involved a convenience sample of 30 individuals who were 60 years and above and were recruited from two old age homes. Reaction time was assessed twice in a day that is once in the morning and once in the evening to check if reaction time has a relation with the level of alertness based on the subtype according to Morningness-Eveningness Questionnaire. Outcome measures include Morningness-Eveningness Questionnaire and Ruler Drop Test. RESULT: The evening type had a faster reaction time in the evening as compared to the morning type or intermediate type. But no change in the reaction time in the morning and the morning type. Conclusion: The main objective of this study was to find out the reaction time depending on the level of alertness. It was found that the participants who were evening type indicating high alertness in the evening had a faster reaction time when evaluated in the evening.
