A Comparison of Dominant and Non-Dominant Hand StrengthsFrom the Centre for Rehabilitation Science, University of Manchester, Manchester, UK Correspondence: Professor J. A. Oldham, Centre for Rehabilitation Science, Manchester Royal Infirmary, Oxford Road, Manchester M13 9WL, UK. E-mail: jackie.oldham{at}man.ac.uk This study compares dominant and non-dominant hand strength in both right- and left-handed participants. Maximum voluntary contraction (MVC) of the first dorsal interosseous (FDI) muscle, power grip strength and pulp-to-pulp pinch strength were assessed under carefully controlled conditions. No significant differences were observed between dominant and non-dominant hands in left-handed participants for all tests. Small but significant differences (0.1–3%) were observed between dominant and non-dominant hands in right-handed participants for all three tests. These differences were much smaller than those reported in other studies. Furthermore, considerable variability was observed in the relative strengths of the two hands for each participant. We conclude that clinicians must be cautious when using the 10% rule to make comparisons between injured and uninjured hands.
