The grip strength survey in infants (0-2 years old) and study of their development progress

Abstract

The aim of this study was to clarify the grip strength and progress of development in infants aged 0 to 2 years old. The subjects were 396 infants and we measured their grip strength with grip dynamometer （T. K. K. 1269r） for the infants. Date on 313 subjects out of the 396 were analyzed. The average of grip strength was followed：0 to 5 months was 0.81 kg, 6 to 11 months was 1.05 kg, 12 to 17 months was 1.45 kg, 18 to 23 months was 1.72 kg, 24 to 29 months was 2.31 kg and 30 to 35 months was 3.00 kg. Significant difference between boys and girls were not shown. The relationships between grip strength and age was the most significant, then height and weight next to age. Grip strength increased with age, as a result, we were able to draw the growth diagrams for grip development in infants aged 0 to 2 years old.
