Norms for hand grip strength of healthy children are presented. Sex and age specific centiles for age 5 to 18 years have been determined using a portable strain gauge dynamometer with an accuracy of 0.5 N. The test group comprised 1417 healthy, urban school children from a middle class suburb of Brisbane. Mean maximum grip strength (of four tests, two with each hand) and mean peak grip strength (best of four tests) were recorded. Mean values of peak grip strength were 10 to 15% higher than the average maximum grip in all age groups. At all ages girls had a reduced grip strength compared with boys and although boys manifested a continual, approximately linear increase in grip strength through all age groups, girls manifested an approximately linear increase up to 13 years after which mean hand grip usually remained constant. By the age of 18 years boys had a mean grip strength some 60% higher than girls. Correlations with height and weight are also presented. "Handedness' influenced grip strength and was most noticeable in children aged over 10 years. The clinical use of hand grip strength centiles for the early indication of neurological and muscular disorders and for following the natural history of neuromuscular disease is discussed.
本文给出了健康儿童握力的标准。使用精度为0.5牛的便携式应变片测力计，确定了5至18岁按性别和年龄划分的百分位数。测试组由来自布里斯班一个中产阶级郊区的1417名健康城市学童组成。记录了平均最大握力（四次测试，每只手各两次）和平均峰值握力（四次测试中的最佳值）。在所有年龄组中，峰值握力的平均值比平均最大握力高10%至15%。在所有年龄段，女孩的握力均低于男孩，尽管男孩在所有年龄组中握力都呈现持续、近似线性的增长，但女孩在13岁之前握力近似线性增长，之后平均握力通常保持不变。到18岁时，男孩的平均握力比女孩高约60%。文中还给出了握力与身高和体重的相关性。“用手习惯”会影响握力，在10岁以上儿童中最为明显。文中讨论了握力百分位数在早期指示神经和肌肉疾病以及跟踪神经肌肉疾病自然病程方面的临床应用。
