Handedness is an individual's preference to use one hand performing activities such as cutting with a knife or writing. Handedness is divided into two, right-handed and left-handed. Handedness can be influenced by genetics, prenatal development, and parenting. This study aims to analyse the categorization of handedness based on self-confessed, 10 daily uni-manual activities and hand strength performance. This study was conducted for 1 month by visiting a crowd of more than two people and providing a consent sheet following the questionnaire, personal data questionnaire including sex and age, 10 daily activity questionnaires and power grip questionnaires accompanied by power grip measurements using a dynamometer. A total of 610 individuals were assessed. The study showed that handedness could be determined by assessing self-confessed, 10 daily uni-manual activities with addition of hand strength performance. The older a person was the stronger the power grip value, those with a right-handed preference had a greater right handgrip value. Age was found did not affect handedness. © Published under licence by IOP Publishing Ltd.
