Correlation Matrix Between Age, Dynamic Manipulation Score, Nine Hole Peg Test and Box and Blocks Test

	Age	Dynamic Manipulation Score	Nine Hole Peg Test	Box and Blocks Test
Age	1.00	−0.39*	0.48*	−0.37*
Dynamic Manipulation Score		1.00	−0.23	0.15
Nine Hole Peg Test			1.00	−0.68*
Box and Blocks Test				1.00

Notes: The positive values indicate an increase, whereas negative values indicate a decrease. The bottom half of the matrix is not shown for clarity. The first row shows that all the measures are significantly correlated with age, whereas our stepwise regression results indicate that the Nine Hole Peg Test and Dynamic Manipulation Score account for most of the variance in age (45–89 y).

*Significant correlation at p < .008, based on a Bonferroni correction.
