本文对17例脑瘫患儿进行了后续行动的预期任务目标对预期目标前的达成模式的影响研究。作者假设，当患有CP的儿童使用他们受影响较小的手时，他们不会受到任务目标的影响，并且他们的伸手模式将偏离17名年龄匹配的无CP儿童和20名年轻健康成人参与者。所有的参与者被指示达到和抓住一个网球，然后要么适合或抛出它。运动学变量（运动时间，直线率，峰值速度，峰值速度的时间百分比，和运动单位的数量）被用作结果的措施。与没有CP的儿童和成人相比，CP儿童使用更慢，更少的直线，更少的力量和更急的接触模式来接近物体。不像没有CP的儿童和成人。后续行动的预期目标不影响CP儿童在预期目标之前的达成模式。因此，患有CP的儿童可能难以进行预期计划，因此必须将综合行动计划分割成连续的子运动。
The authors examined whether the intended task goal of the subsequent action affects the reaching patterns before he intended goal in 17 children with cerebral palsy (CP). The authors hypothesized that when the children with CP used their less affected hand, they would not be affected by the task goals and that their reaching pattern would deviate from those of 17 age-matched children without CP and 20 young healthy adult participants. All participants were instructed to reach and grasp a tennis ball and then to either fit or throw it. Kinematic variables (movement time, straightness ratio, peak velocity, percentage of time to peak velocity, and number of movement units) were used as outcome measures. Children with CP used slower, less straight, less forceful, and jerkier reaching patterns to approach the object than did children without CP and adults. Unlike in children and adults without CP. the intended goal of the subsequent action did not affect the reaching pattern before the intended goal in children with CP. Children with CP may therefore have difficulty in anticipatory planning and thus must segment the integrative action plan into sequential submovements.
