The study to establish the normal values of the height of foot arch in the healthy persons

1.足弓高值率信度和足趾屈肌力效度结果本研究以20名师范大学生为研究对象，随机分为训练组(T组)和非训练组(NT组)进行测量，并检验两组测量值的一致性程度，两者均为我们共同允许的高信度，但T组的径向下端测量的不平度最小。并用数字测力仪和足底压力图系统(力敏应用：FSA)测量了足趾屈肌力量和足趾踩踏力量(力敏应用：FSA)，脚趾屈肌力量/趾踏力量/足底压力分布测量显示两者相关性高，重复性好。学龄前儿童足部的研究我们对236名学龄前儿童的足部进行了调查。因此，…青少年儿童给扁平型足迹的比例高共44.9%。拇外翻占20.1%，浮趾占73.7%。小学生足部的研究我们对219名一年级到六年级的儿童进行了足部调查。弓形率高达11~12%，牙弓发育缓慢。平板型脚印最多，一年级男生占44.4%。拇外翻随年级的增长呈上升趋势，五年级女生平均为14.3度，13度以上者占46.4%。在六年级的男孩中，53.6%的人达到了13度以上。小趾内翻10度以上，五年级为50%，六年级为70%。初中生足部状况的研究我们对103名一年级到三年级的学生进行了足部状况调查。弓形率一年级为10.5±3.8%，二年级为10.5±3.0%，三年级为11.9±2.8%。扁平型的足迹一年级为18.8%，二年级为11.1%，三年级为12.9%。拇外翻角度随年级的提高而增大，52.9%的三年级学生拇外翻角度大于13度。两组差异无统计学意义，64.3%的三年级学生小趾内翻大于10°，男女差异无统计学意义。以往的一些研究表明，在初中生中，拇指外翻的发生率为54.7%(1.8%)和35.0%(2.9%)，远远超过了以往的一些研究结果。较少

1. The reliability of arch high rate and the validity of strength of toe flexors As a result of we intended for 20 normal university students and divided it into training group (T group) and the non-training group that we did not practice (NT group) which practiced the measurement at random, and having examined the agreement degree of the value, both the group high reliability that we could permit together was provided, but there was the least unevenness measurements in the radiale bottom end of T group.As a result of we intended for 50 normal university students, and having measured strength of toe flexors and stamping power by toes with a digital hand dynamometer and foot pressure mapping system (force sensitive applications: FSA), strength of toe flexors / stamping power by toes / the foot pressure distribution measurements showed correlation high both, and reproducibility was high.2. The research of feet in preschoolers We investigated of feet in 236 preschoolers. As a result, the … More ratio that youth child gave footprint of the flat type was 44.9% altogether highly. We found valgus hallux 20.1%, float toe 73.7%.3. The research of feet in the elementary schoolchildren We investigated of feet in 219 children from a first grader to a sixth grader. Their arch high rate was 11-12%, that development of their arch was slow. There was the most footprint of the flat type with 44.4% in the boy of the first grader. The hallux valgus increased with grade progress surely, and average was 14.3 degrees in fifth grader girls, and the children more than 13 degrees occupied 46.4%. With the sixth grader boys, 53.6% came more than 13 degrees. More than 10 degrees of varus of lesser toe was 50% with fifth graders, and 70% with sixth graders.4. The research of feet in the junior high students We investigated of feet in 103 students from a first grader to a third grader. Their arch high rate was 10.5±3.8% in first grader, 10.5±3.0% in second grader, 11.9±2.8% in third grader. The footprint of the flat type was 18.8% of first grader, 11.1% of second grader, 12.9% of third grader. The hallux valgus angle increased with grade progress, and 52.9% of the third grader had more than 13 degrees. There was not significant, and 64.3% of the third grader were over varus of lesser toe more than 10 degrees with man and woman. Some past studies described that one for four girls and the one for seven boys have hallux valgus in the junior high student conventionally, but this result that 54.7% (one for 1.8 girls) and 35.0% (one for 2.9 boys) have hallux valgus exceeded far some past results.
