Abstract: Objective To investigate the effect of types of pinch on the measurement of pinch strength in healthy young subjects.Methods All anthropometric factors of 20 right-handed young volunteers(10 males,and 10 females)were recorded.Their pinch strength in 3 types(I.e.Pulp2,Chuck,and Lateral)were measured with digital pinch dynamometer in standardized position.Results For both genders,the pinch strength of Lateral was the largest,followed by Chuck,Pulp2 and the dominant hand was stronger(P<0.01).Men were stronger than women in all types of pinch strength(P<0.01).Correlation among the 3 types of pinch strength were presented(r=0.568~0.707,P<0.01).The correlation were found between the pinch strength of 3 types and weight in women(r=0.764~0.807).No correlation has been found among the pinch strength of 3 types and age,height,the thickness of palm in both the males and the females.Conclusion The sex and types of pinch significantly impact pinch strength in healthy young subjects,but the correlation between pinch strength and anthropometry should be further surveyed.
