This study measured the rate of acquisition of head and trunk postural control during the two early developmental periods of independent walking, as defined by global gait parameters. Gait parameters were observed longitudinally in four children. The maximum angular deviations of the trunk and head oscillations were computed in the frontal and sagittal planes. These decreased most dramatically during the first 10-15 weeks of independent walking, during the same period when global gait parameters changed rapidly. This head and trunk stabilization may be a fundamental process that help to maintain equilibrium during walking, and may be a necessary step prior to the development of fine posturo-motor control.
本研究测量了由整体步态参数定义的两个独立行走早期发育阶段中头部和躯干姿势控制的习得率。对四名儿童的步态参数进行了纵向观察。计算了躯干和头部摆动在额面和矢状面的最大角度偏差。在独立行走的前10 - 15周内,这些偏差下降最为显著,而这一时期整体步态参数变化迅速。这种头部和躯干的稳定可能是在行走过程中帮助维持平衡的一个基本过程,并且可能是精细姿势运动控制发展之前的一个必要步骤。
