The influence of ethnic differences based on upper limb anthropometry on grip and pinch strength

Abstract

BackgroundEthnic differences in upper limb anthropometry have significant variations which can influence surgical outcomes and rehabilitation. We hypothesize that there would be a significant difference in the anthropometry based on ethnicity and gender which will reflect on objective measurements. MethodsWe performed 13 anthropometric measurements of the upper limb, grip and three types of pinch strength in 210 volunteers across seven ethnicities in young adults at our university campus. We compared them statistically based on ethnic and gender differences. ResultsThere was a significant correlation noted between grip, palmar and tip to tip pinch strength in 12 of the 13 anthropometric measurements. Key pinch correlated with eight parameters. Mean grip and pinch strength are noted to be more in males and from developed nations across all ethnicities. ConclusionsThis study shows that there is significant variation between the anthropometric measurements based on gender and ethnicity which correlates with differences in grip and pinch strength.
