根据压力中心(COP)记录分析的最新进展，我们研究了10名脑性瘫痪(CP)儿童和9名典型发育(TD)儿童的COP轨迹结构，他们安静地站着，睁眼(EO)和闭眼(EC)，并同时进行视觉COP反馈(FB)。特别是，我们从摇摆的数量和规律性两个方面量化了警察的轨迹。我们的假设是：(1)与TD儿童相比，CP儿童表现出更大的摇摆量和更规则的摇摆；(2)同时视觉反馈(为姿势控制创造外部功能语境，引起更多的外部注意焦点)减少了TD和CP儿童的摇摆量和摇摆规律性，而闭上眼睛则相反。这些数据与这两种假设基本一致。与TD儿童相比，CP儿童的摇摆量更大，而摇摆量更规则。此外，与EO和EC条件相比，并发视觉反馈的存在导致较少的规则摆动。这种影响在CP组中不那么明显，因为在EO条件下姿势图最规则，而在EC条件下，与对照组一样。尽管如此，我们的结论是，CP儿童可能受益于包括姿势任务和外部功能背景的姿势控制的治疗。
Following recent advances in the analysis of centre-of-pressure (COP) recordings, we examined the structure of COP trajectories in ten children (nine in the analyses) with cerebral palsy (CP) and nine typically developing (TD) children while standing quietly with eyes open (EO) and eyes closed (EC) and with concurrent visual COP feedback (FB). In particular, we quantified COP trajectories in terms of both the amount and regularity of sway. We hypothesised that: (1) compared to TD children, CP children exhibit a greater amount of sway and more regular sway and (2) concurrent visual feedback (creating an external functional context for postural control, inducing a more external focus of attention) decreases both the amount of sway and sway regularity in TD and CP children alike, while closing the eyes has opposite effects. The data were largely in agreement with both hypotheses. Compared to TD children, the amount of sway tended to be larger in CP children, while sway was more regular. Furthermore, the presence of concurrent visual feedback resulted in less regular sway compared to the EO and EC conditions. This effect was less pronounced in the CP group where posturograms were most regular in the EO condition rather than in the EC condition, as in the control group. Nonetheless, we concluded that CP children might benefit from therapies involving postural tasks with an external functional context for postural control.
