This study evaluated the effectiveness of adapted Taekwondo (TKD) training on skeletal development and motor performance in children with developmental coordination disorder (DCD). One hundred forty-five prepubertal children with DCD were allocated to either the TKD or control groups. Children in the TKD group participated in a weekly 1-hour adapted TKD intervention and daily TKD home exercises for 12 weeks. The primary outcome (delay in skeletal development) and secondary outcomes (Movement Assessment Battery for Children (MABC) total impairment score, eye-hand coordination (EHC) scores, and a standing balance score) were measured at baseline, after the intervention and 3 months after the intervention. Skeletal development improved in both groups over time (p < 0.017). The TKD group had a significant delay in skeletal development at baseline compared to the control group (p = 0.003) but caught up with the controls at 3 months (p = 0.041). Improvements in the MABC scores were also seen in both groups across time (p < 0.017). Only the TKD group had a significant improvement in the EHC movement time at 3 (p = 0.009) and 6 months (p = 0.016). The adapted TKD intervention may be effective in improving the skeletal development and EHC movement time of children with DCD. For motor performance, the effect of maturation might be more profound.
本研究评估了改编跆拳道（TKD）训练对发育性协调障碍（DCD）儿童骨骼发育和运动表现的有效性。145 名青春期前 DCD 儿童被分配到 TKD 组或对照组。TKD 组的儿童每周参加 1 小时的改编 TKD 干预和 12 周的 TKD 家庭日常练习。主要结局（骨骼发育延迟）和次要结局（儿童运动评估电池（MABC）总损伤评分、手眼协调（EHC）评分和站立平衡评分）在基线、干预后和干预后 3 个月进行测量。两组的骨骼发育随时间推移而改善（p<0.017）。TKD 组在基线时与对照组相比，骨骼发育明显延迟（p=0.003），但在 3 个月时与对照组相匹配（p=0.041）。两组的 MABC 评分也随时间推移而改善（p<0.017）。只有 TKD 组在 3 个月（p=0.009）和 6 个月（p=0.016）时 EHC 运动时间有显著改善。改编的 TKD 干预可能对改善 DCD 儿童的骨骼发育和 EHC 运动时间有效。对于运动表现，成熟的影响可能更为深远。
