The aim of the study was to determine psychometric characteristics of a new test for the evaluation of dynamic balance in healthy individuals. The research was conducted on a sample of 60 female students (21.18±.86 years). The participants performed three trials of the new test for each of the two different ways of walking. The results of reliability have shown high values of factor loadings (.91-.97) and standardized Cronbach’s alpha values (.87-.98), as well as the average inter-item correlation values (full feet walking, tip toe walking and the number of steps) (.78-.94). High values of factor loadings (.88-.97) and the fact that the total explained variance was very high (93.3%), with a relatively small variability between the attempts, suggests that all the rules for consistency of testing have been satisfied and that the new test is reliable enough for its application in practice.
