Handwriting skills are important for the academic life of children and the lack of visual-motor performance leads to writing problems in children with low vision. This study aims to reveal handwriting kinematics and pencil grip features in children with low vision by means of a novel method.
18 children with low vision (mean age: 9.83 ± 1.54 years) and 18 children with typical development (mean age: 9.83 ± 1.62 years) were included in the study. Children performed a sentence writing task on a digitizer tablet. During the task, the writing hand of children was photographed to analyze pencil grip patterns.
Children with low vision performed greater stroke size except for the vertical size, slower writing speed, more dysfluent movements, and less pen pressure than children with typical development. However, participants preferred mature pencil grip patterns and had high grip scores independent from the diagnosis.
The findings indicate that children with low vision have difficulties in handwriting in terms of spatial and temporal features. These results would be important for interventions to develop specific programs on writing skills to support their educational life.
书写技能对于儿童的学业生活很重要，而视动表现不佳会导致低视力儿童出现书写问题。本研究旨在通过一种新方法揭示低视力儿童的笔迹运动学和握笔特征。
本研究纳入了 18 名低视力儿童（平均年龄：9.83±1.54 岁）和 18 名具有典型发育的儿童（平均年龄：9.83±1.62 岁）。儿童在数位板上完成句子书写任务。在任务过程中，拍摄儿童的书写手以分析握笔模式。
与具有典型发育的儿童相比，低视力儿童的笔画大小较大（垂直方向除外），书写速度较慢，运动流畅性较差，笔压较小。然而，参与者更喜欢成熟的握笔模式，且握笔得分较高，与诊断无关。
这些发现表明，低视力儿童在空间和时间特征方面存在书写困难。这些结果对于开展针对书写技能的特定干预计划以支持其教育生活非常重要。
