title: The effects of age and sex on hand movement structure.
abstract: The aim was to investigate the effects of age and sex on hand function and ascertain age-related changes (magnitude and rate) by assessing a broad range of functional tasks with the dominant and non-dominant hands. A representative sample of 635 adults (114 males and 491 females) aged 50 years and over completed motor performance series of the Vienna Test System Parametric and non-parametric analysis and simple linear regression was used to examine the relationships. Significant relationships were observed between task performance and age and sex, although the contributions of both factors differed by varying degree. Compared with males, the females performed significantly better than males in the majority of tests, particularly with the dominant hand, although greater age-related reductions were observed in performance. Among the skills quantifying hand function, age accounted for the most variance in hand and finger dexterity.
