与健康儿童相比，患有发育协调障碍（DCD）的儿童姿势控制能力较差，更容易跌倒和受伤。运动训练可以改善这一人群的感觉组织和平衡能力。本研究旨在评估三个月的跆拳道训练对DCD儿童感觉组织和站立平衡的影响。这是一项随机对照试验。44名DCD患儿（平均年龄：7.6 +/- 1.3岁）和18名正常发育儿童（平均年龄：7.2 +/- 1.0岁）参与了研究。随机选择21例DCD患儿，每天进行TKD训练，为期3个月（每天1小时）。23名患有DCD的儿童和18名正常发育的儿童没有接受任何训练作为对照组。分别采用感觉组织测试（SOT）和单侧站立测试（UST）评估感觉组织和站立平衡。重复测量MANCOVA组受时间互作效应显著。事后分析表明，DCD-TKD组前庭比值（p = 0.003）和UST摇摆速度（p = 0.007）的改善明显大于dcd -对照组。TKD训练3个月后，DCD-TKD组与正常对照组的平均前庭比值和UST摇摆速度差异无统计学意义（p < 0.05）。TKD训练后体感觉比值无明显变化（p < 0.05）。视觉比例和前庭比例都有显著改善。训练后，DCD-TKD组的SOT综合评分和UST摇摆速度也被观察到(p
Children with developmental coordination disorder (DCD) have poorer postural control and are more susceptible to falls and injuries than their healthy counterparts. Sports training may improve sensory organization and balance ability in this population. This study aimed to evaluate the effects of three months of Taekwondo (TKD) training on the sensory organization and standing balance of children with DCD. It is a randomized controlled trial. Forty-four children with DCD (mean age: 7.6 +/- 1.3 years) and 18 typically developing children (mean age: 7.2 +/- 1.0 years) participated in the study. Twenty-one children with DCD were randomly selected to undergo daily TKD training for three months (1 h per day). Twenty-three children with DCD and 18 typically developing children received no training as controls. Sensory organization and standing balance were evaluated using a sensory organization test (SOT) and unilateral stance test (UST), respectively. Repeated measures MANCOVA showed a significant group by time interaction effect. Post hoc analysis demonstrated that improvements in the vestibular ratio (p = 0.003) and UST sway velocity (p = 0.007) were significantly greater in the DCD-TKD group than in the DCD-control group. There was no significant difference in the average vestibular ratio or UST sway velocity between the DCD-TKD and normal-control group after three months of TKD training (p > 0.05). No change was found in the somatosensory ratio after TKD training (p > 0.05). Significant improvements in visual ratios, vestibular ratios. SOT composite scores and UST sway velocities were also observed in the DCD-TKD group after training (p
