The authors analyze the influence of different sitting positions (ring and flexion) on the reaching performance (spatiotemporal variables) of full-term infants 6 and 7 months old. In addition, they correlated level of trunk control, measured by the Segmental Assessment of Trunk Control, with performance during reaching. The different sitting positions only influenced the reaching movements of 6-month-old infants, who showed the best performance in the ring position. However, this influence was observed only for the trunk displacement, deceleration time, movement units, straightness index and mean velocity. In contrast, there was no influence of positions on 7-month-old infants' reaching performance. Regarding the correlations, it was observed that infants with more level of trunk control showed a better performance when reaching, regardless of position and the age assessed.
作者分析了不同坐姿（环形坐姿和屈曲坐姿）对6个月和7个月大的足月儿伸手够物表现（时空变量）的影响。此外，他们将通过躯干控制分段评估法测量的躯干控制水平与伸手够物时的表现进行了关联。不同的坐姿仅影响6个月大婴儿的伸手够物动作，他们在环形坐姿下表现最佳。然而，这种影响仅在躯干位移、减速时间、运动单元、直线度指数和平均速度方面观察到。相比之下，坐姿对7个月大婴儿的伸手够物表现没有影响。关于相关性，观察到无论评估的姿势和年龄如何，躯干控制水平较高的婴儿在伸手够物时表现更好。
