Abstract

This study analyzed the grip and pinch strength of children aged 7 to 12 years old in order to establish the relationship between hand strength and anthropometric factors. Two hundred and two children in primary school were divided into three groups based on age, with group A aged 7 to 8 years, group B aged 9 to 10 years, and group C aged 11 to 12 years old. A Jamar dynamometer was used to measure subjects’ grip strength, and a B&L pinch gauge was used to measure their tip, palmar, chuck, and key pinch strength.Significant differences were found between left and right hand gripping and all pinch forces among all age groups. The strength was greatest in group C, lower in group B, and lowest in group A. The strength of the key pinch was the largest and the strength of the tip pinch was the smallest. The boys generated significantly larger forces than the girls in all strength tests among individual age groups. The gender differences in tested strengths were most remarkable in group C. Stepwise linear regression was used to analyze the relationship between hand strength and anthropometric factors. The linear regression equations with correlation coefficient up to 0.7-0.8 (all p＜0.001) were adopted for grip and all pinch strength. The results showed that the grip and all pinch strengths were positively correlated with forearm circumference and negatively correlated with thickness of the triceps skinfold. Forearm circumference proved to be a better predictor of hand strength than mid-arm circumference and skinfold thickness. Grip, tip and palmar strengths were positively correlated with age. Grip, chuck, and key strengths were positively correlated with body height and weight. Palmar strength was positively correlated with body weight. Tip strength was positively correlated with body height. The norms of grip and all pinch strengths in this study may serve to provide a reference for clinicians and therapist involved with hand rehabilitation in children.
