The organization of interlimb coordination was studied in newly walking infants with and without support and in infants who had been walking 0.5, 1, 3, and 6 months. Analysis of the temporal and distance phase relationships between the limbs revealed that newly walking infants exhibit interlimb coordination similar to that of mature walkers. The coupling between the limbs, however, is loosely constrained, approaching adult-like consistency after 3 months of walking. Providing support for the newly walking infant afforded a more consistent, mature coordination suggesting that neuromuscular development is in advance of its ability to function in the physical world.
研究了刚开始走路的婴儿在有支撑和无支撑情况下的双侧肢体协调情况，以及已经行走0.5、1、3和6个月的婴儿的双侧肢体协调情况。对肢体之间的时间和距离相位关系进行分析后发现，刚开始走路的婴儿表现出与成熟步行者相似的双侧肢体协调。然而，肢体之间的耦合约束较松散，在行走3个月后接近成人般的一致性。为刚开始走路的婴儿提供支撑能带来更一致、成熟的协调，这表明神经肌肉发育先于其在现实世界中发挥功能的能力。
