In this study we analysed the potential spin-off of magnifier training on the fine-motor skills of visually impaired children. The fine-motor skills of 4- and 5-year-old visually impaired children were assessed using the manual skills test for children (6-12 years) with a visual impairment (ManuVis) and movement assessment for children (Movement ABC), before and after receiving a 12-sessions training within a 6-weeks period. The training was designed to practice the use of a stand magnifier, as part of a larger research project on low-vision aids. In this study, fifteen children trained with a magnifier; seven without. Sixteen children had nystagmus. In this group head orientation (ocular torticollis) was monitored. Results showed an age-related progress in children's fine-motor skills after the training, irrespective of magnifier condition: performance speed of the ManuVis items went from 333.4s to 273.6s on average. Accuracy in the writing tasks also increased. Finally, for the children with nystagmus, an increase of ocular torticollis was found. These results suggest a careful reconsideration of which intervention is most effective for enhancing perceptuomotor performance in visually impaired children: specific 'fine-motor' training or 'non-specific' visual-attention training with a magnifier.
在这项研究中，我们分析了放大镜训练对视障儿童精细运动技能的潜在衍生影响。使用儿童手动技能测试（适用于视力障碍儿童的 6-12 岁）（ManuVis）和儿童运动评估（Movement ABC），在 6 周内接受 12 次训练之前和之后，评估了 4 岁和 5 岁视障儿童的精细运动技能。该训练旨在练习使用站立式放大镜，作为对低视力辅助设备的更大研究项目的一部分。在这项研究中，十五名儿童接受了放大镜训练；七名没有接受。十六名儿童有眼球震颤。在这个组中，监测了头部方向（眼性斜颈）。结果表明，无论是否使用放大镜，儿童的精细运动技能在训练后都有与年龄相关的进步：ManuVis 项目的执行速度平均从 333.4 秒提高到 273.6 秒。书写任务的准确性也提高了。最后，对于患有眼球震颤的儿童，发现眼性斜颈增加了。这些结果表明，对视障儿童感知运动表现最有效的干预措施需要仔细重新考虑：是特定的“精细运动”训练，还是使用放大镜进行“非特定”视觉注意力训练。
