The objective of this study was to establish normative data concerning grasp and pinch strength for use by clinicians who are treating children with hand problems. A population of 474 children ages 5 to 12 were tested using the Jamar dynamometer and the Preston pinch guage. Means and standard deviations of all measurements for all subjects were determined. Results of the study indicate that there is a steady increase in both grasp and pinch strength that coincides with the increase in chronological age and development; males are consistently stronger than females across the age range in all tests, although the differences are not striking. Hand dominance was judged not to be an important factor in predicting strength in this population.
