The aim of the present study was to analyze the ability to programme and execute reaching movements in individuals with myelomeningocele (MMC) and in a control group. Thirty-one participants (18 males, 13 females; mean age 12 years 11 months, SD 2 years 7 months, range 9 to 19 years) with MMC and 31 participants (matched for age and sex) without disabilities were investigated. Reaching was performed with and without visual feedback toward three targets displayed on a computer screen and data were collected using a digitizing tablet linked to a computer. The kinematics of reaching were analyzed and analysis of variance was used for statistical analysis. Results showed that both groups were able to programme reaching movements under both visual conditions. Although the execution of reaching was poor in the MMC group compared with the control individuals, as indicated by larger end-point errors (p=0.002), less straight movements (p=0.018), and shorter deceleration phases (p=0.004), movement time was not prolonged in the MMC group. Those with shunt treatment (n=21) had more difficulties when visual feedback was provided. Those with symptoms of early brainstem dysfunction (n=5) had shorter deceleration phases under both visual conditions.
本研究的目的是分析脊髓脊膜膨出症（MMC）患者和对照组个体规划和执行伸手动作的能力。对31名患有MMC的参与者（18名男性，13名女性；平均年龄12岁11个月，标准差2岁7个月，年龄范围9至19岁）和31名无残疾的参与者（年龄和性别匹配）进行了调查。在有和没有视觉反馈的情况下，向电脑屏幕上显示的三个目标进行伸手动作，并使用连接到电脑的数字化写字板收集数据。对伸手动作的运动学进行了分析，并使用方差分析进行统计分析。结果表明，两组在两种视觉条件下都能够规划伸手动作。尽管与对照组个体相比，MMC组的伸手动作执行较差，表现为更大的终点误差（p=0.002）、更不直的动作（p=0.018）和更短的减速阶段（p=0.004），但MMC组的运动时间并未延长。接受分流治疗的患者（n=21）在提供视觉反馈时遇到更多困难。有早期脑干功能障碍症状的患者（n=5）在两种视觉条件下的减速阶段都较短。
