Effect of age on hand dominance in healthy population of 60 to 80 years: An observational study

With increasing age, a decline in hand movement coordination occurs, which can lead to a decreased ability to cany out everyday activities. 103 elderly persons both male and female of age 60 to 80 years, were randomly selected from an old age home to study hand differences in their task performance (Hand Dominance). Edinburgh Handedness Questionnaire (EHQ) was used to check hand dominance. This questionnaire contains one question about the hand you preferentially use for writing and ten questions about your handpreference for other activities. Hand-Held Dynamometer (HHD) was also used to check right and left-hand grip strength and was measured in kilograms. After analyzing the responses from the participants of the study, it was found that there is no correlation between age with hand dominance (r = 0.108). The correlation value between age and right and left-hand grip strength was documented as 0.434 and 0.403 respectively. The mean and standard deviation of EHQ were 485.19 and 15.03 respectively. The mean and Standard donation of the right and left-handgrip strength (measured in kg) was 12.21 and 10.45 respectively, which was obtained using SPSS version 23. Based on the present findings it may be concluded that there is no correlation between age with hand dominance and handgrip strength. Hand dominance does not change with the advancing age.
