Abstract
Objective: Effect of fatigue on balance and dual task performance in elderly
Background: Fatigue has been defined as time related phenomenon of decline in the maximal force generating capacity in medical literature usually defined Fatigue in the sense of experienced fatigue as an overwhelming sense of tiredness, lack of energy and feeling of exhaustion. Fatigue as a concept determined by two dimensions psychological and physiological.
Study design: Experimental study.
Methods: A total of 31 subjects with 24 male and 7 female participated in the study based on inclusion exclusion criteria. Subjects were recruited from general community dwelling people.
Results: There is significant difference in pre and post fatigue B.B.S score. p<.005 there is significant reduction in post fatigue value also in case of calculation error p<.005 that is significant increment in post fatigue calculation error. In case of gait sped p<.005 means there is significant increment in post fatigue gait speed.
Conclusion: In the present study we investigated that fatigue impaired the balance in elderly. Also have effect on cognition. We found that gait speed is increased in elderly during dual task performance and make them more susceptible to fall. So, fatigue is one of the causes of risk falls in elderly. Also fatigue places higher demand of attention during performance of task.
Keywords: Fatigue, BBS score, dual task, balance, gait, elderly.
