Description
A fine and coarse motor performance decline, evaluated by the times needed to complete motor trials of increasing difficulty, was observed in the elderly compared to young adults. Fine motor performance was better in the dominant hand regardless of age, while no significant difference was observed for coarse motor performance. No gender differences were observed.
