Abstract: Objective To provide therapists,pediatricians and other health-related professionals with preliminary descriptive data on the spherical grip strength of 4~6 years old children. Methods With a stratified random sampling method,1 061 boys and girls were tested using WCS-100 grip dynamometer.The maximum of three trials was used as the grip strength score for each hand.The right and left hands were alternated during testing to allow a 15 seconds rest between trials. Results The average,standard deviation and reference values of eight groups were got respectively.The findings indicated that the maximum grip strength scores increased with an increase in age,the boys' grip strength score was greater than girls' (t=4.426,5.931,5.889,5.478,P＜0.05),and that the right grip strength score was greater than the left(t=-9.260,-9.591,-8.663,-8.709,P＜0.05). Conclusions Grip strength mainly reflects the isometric static muscle strength of the forearm and hand flexor muscle.Grip strength is important in children's writing and activities of daily living.Grip strength measurements were used to assess hand function and fitness.The results can provide clinicians with preliminary descriptive data on the spherical grip strength of 4~6 years old children and provide reference for building the national's norm of grip strength.
