- Domain I is static balance, domain II is postural stability, domain III is dynamic balance, and domain IV (sum of domains I, II, and III) is balance performance. Items are named as domain number followed by item number, for example, II 7 indicates the item 7 which is in domain II. Items were numbered consecutively through the whole balance testing scale. The 16 items of the balance testing scale were subjected to factor analysis, the extraction method was principal component analysis, and the rotation method was Varimax with Kaiser Normalization. Three factors were retained because their Eigenvalues were greater than 1 and their cumulative contribution to the total variance reached 72.0%. Numbers with absolute values greater than 0.1 were in bold
