Abstract

PURPOSE

To measure and compare hand function for children with normal hand development, congenital hand differences (CHD), and neuromuscular disease (NMD) using a function test with touch screen technology designed as an iPhone application.

METHODS

We measured touch screen hand function in 201 children including 113 with normal hand formation, 43 with CHD, and 45 with NMD. The touch screen test was developed on the iOS platform using an Apple iPhone 4. We measured 4 tasks: touching dots on a 3 × 4 grid, dragging shapes, use of the touch screen camera, and typing a line of text. The test takes 60 to 120 seconds and includes a pretest to familiarize the subject with the format. Each task is timed independently and the overall time is recorded.

RESULTS

Children with normal hand development took less time to complete all 4 subtests with increasing age. When comparing children with normal hand development with those with CHD or NMD, in children aged less than 5 years we saw minimal differences; those aged 5 to 6 years with CHD took significantly longer total time; those aged 7 to 8 years with NMD took significantly longer total time; those aged 9 to 11 years with CHD took significantly longer total time; and those aged 12 years and older with NMD took significantly longer total time.

CONCLUSIONS

Touch screen technology has becoming increasingly relevant to hand function in modern society. This study provides standardized age norms and shows that our test discriminates between normal hand development and that in children with CHD or NMD.

TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic III.

摘要

目的

使用一款设计为iPhone应用程序的触摸屏技术功能测试，测量并比较手部发育正常、先天性手部差异（CHD）和神经肌肉疾病（NMD）儿童的手部功能。

方法

我们测量了201名儿童的触摸屏手部功能，其中包括113名手部形态正常的儿童、43名患有CHD的儿童和45名患有NMD的儿童。触摸屏测试是在iOS平台上使用苹果iPhone 4开发的。我们测量了4项任务：触摸3×4网格上的点、拖动形状、使用触摸屏相机以及输入一行文本。该测试耗时60至120秒，包括一个预测试，以使受试者熟悉测试形式。每项任务独立计时，并记录总时间。

结果

手部发育正常的儿童随着年龄增长完成所有4项子测试所需时间减少。将手部发育正常的儿童与患有CHD或NMD的儿童进行比较时，我们发现5岁以下儿童差异极小；5至6岁患有CHD的儿童总用时显著更长；7至8岁患有NMD的儿童总用时显著更长；9至11岁患有CHD的儿童总用时显著更长；12岁及以上患有NMD的儿童总用时显著更长。
