%X Background Measuring grip and pinch strength is an important part of hand injuryevaluation. Currently, there are no standardized values of normal grip and pinch strengthamong the Korean population, and lack of such data prevents objective evaluation of postsurgicalrecovery in strength. This study was designed to establish the normal values of gripand pinch strength among the healthy Korean population and to identify any dependentvariables affecting grip and pinch strength.Methods A cross-sectional study was carried out. The inclusion criterion was being a healthyKorean person without a previous history of hand trauma. The grip strength was measuredusing a Jamar dynamometer. Pulp and key pinch strength were measured with a hydraulicpinch gauge. Intra-individual and inter-individual variations in these variables were analyzedin a standardized statistical manner.Results There were a total of 336 healthy participants between 13 and 77 years of age.As would be expected in any given population, the mean grip and pinch strength wasgreater in the right hand than the left. Male participants (137) showed mean strengthsgreater than female participants (199) when adjusted for age. Among the male participants,anthropometric variables correlated positively with grip strength, but no such correlationswere identifiable in female participants in a statistically significant way.Conclusions Objective measurements of hand strength are an important component ofhand injury evaluation, and population-specific normative data are essential for clinical andresearch purposes. This study reports updated normative hand strengths of the South Koreanpopulation in the 21st century.
