This study compared the effectiveness of tai chi (TC) muscle power training (MPT), TC alone, MPT alone, and no training for improving the limits of stability (LOS) and motor and leg muscular performance and decreasing falls in children with developmental coordination disorder (DCD). One hundred and twenty-one children with DCD were randomly assigned to the TC-MPT, TC, MPT, or control group. The three intervention groups received TC-MPT, TC, or MPT three times per week for 3 months. Measurements were taken before and after the intervention period. The primary outcomes were the LOS completion time and dynamic LOS scores. The secondary outcomes included the Movement Assessment Battery for Children-Second Edition total test score and percentile rank, knee muscle peak force and time to peak force, and the number of falls. None of the interventions affected the LOS test scores. Improvements in the peak forces of the knee extensors and flexors were demonstrated in the TC (p = 0.006) and MPT groups (p = 0.032), respectively. The number of falls also decreased in these two groups (p < 0.001). Thus, clinicians may prescribe TC or MPT for children with DCD to increase their knee muscle strength and reduce their risk of falls.
本研究比较了太极拳（TC）肌肉力量训练（MPT）、单独 TC、单独 MPT 和无训练对改善发展性协调障碍（DCD）儿童的稳定性极限（LOS）和运动及腿部肌肉表现以及减少跌倒的效果。121 名 DCD 患儿被随机分配至 TC-MPT、TC、MPT 或对照组。三组干预组每周接受 TC-MPT、TC 或 MPT 三次，共 3 个月。在干预前后进行测量。主要结局是 LOS 完成时间和动态 LOS 评分。次要结局包括儿童运动评估量表-第二版总分和百分位排名、膝关节肌肉峰值力和达峰时间，以及跌倒次数。干预均未影响 LOS 测试成绩。TC（p=0.006）和 MPT 组（p=0.032）的膝关节伸肌和屈肌峰值力均有所提高。这两组的跌倒次数也有所减少（p<0.001）。因此，临床医生可能会为 DCD 患儿开具 TC 或 MPT 的治疗方案，以提高其膝关节肌肉力量并降低跌倒风险。
