A study was conducted on the fine motor skills of 18 kindergarten children undergoing occupational therapy. An index was used to measure the hand use, hand-eye coordination, and manual dexterity of the children before the therapy began and then again after seven months of therapy. The aim of the study was to determine if occupational therapy affected the index score. The data were analysed and the results are presented below.
