The aim of this study was to investigate the effect of different ergonomic desk designs and pencil grip patterns on handwriting performance in children with hemiplegic cerebral palsy and healthy children.
Twenty-six children with left hemiplegic cerebral palsy and 32 typically developing children were included. The Minnesota Handwriting Assessment was used to evaluate handwriting abilities. Pencil grip posture was assessed with a 5-point rating system. Specifically designed adjustable desks and chairs were used. Four different desk types were used in this study: 1) regular desk; 2) regular desk with a 20 degrees inclination; 3) cutout desk; and 4) cutout desk with a 20 degrees inclination.
Statistically significant differences were found between both groups in terms of handwriting ability (p < 0.001). There was no significant difference regarding grip scores between children with cerebral palsy and healthy children (p > 0.05). We found that children with cerebral palsy had better performance using cutout desks in relation to rate and spacing parameters of handwriting (p < 0.05).
The results of our study demonstrated that the pencil grip patterns have no effect on the handwriting parameters in both children with cerebral palsy and healthy children. It is recommended that a cutout table be used to provide more upper extremity support in handwriting activities for students with cerebral palsy.
本研究旨在探讨不同人体工学书桌设计和铅笔握持模式对偏瘫脑瘫儿童和健康儿童书写表现的影响。
纳入 26 名左侧偏瘫脑瘫儿童和 32 名正常发育儿童。采用明尼苏达手写评估评估书写能力。铅笔握持姿势采用 5 分制评分系统进行评估。使用专门设计的可调节桌椅。本研究使用了四种不同类型的桌子：1）常规桌子；2）20 度倾斜的常规桌子；3）切孔桌子；4）20 度倾斜的切孔桌子。
两组儿童在书写能力方面存在统计学差异（p<0.001）。脑瘫儿童和健康儿童的握笔得分之间无显著差异（p>0.05）。我们发现，脑瘫儿童使用切孔桌子在书写速度和间距参数方面表现更好（p<0.05）。
本研究结果表明，在脑瘫儿童和健康儿童中，铅笔握持模式对书写参数没有影响。建议在脑瘫学生的书写活动中使用切孔桌子，以提供更多的上肢支撑。
