患有单侧痉挛性脑瘫（USCP）的儿童在运动规划方面有障碍，影响他们抓握物体的能力。我们研究了规划的手指的位置和力量和灵活性的电机系统，这些在对象操作过程中的协变。11名患有左半球病变（LHL）的儿童、9名患有右半球病变（RHL）的儿童和9名发育正常的儿童（对照组）参与了这项研究。参与者被指示使用他们的优势/较少受影响的手的精确抓握来举起物体并保持物体水平，具有左、居中或右质心（COM）位置。数字位置，力，补偿扭矩和物体滚动测量。尽管USCP儿童通过抬离产生了补偿性扭矩和调制的手指放置，但无论COM位置如何，他们的食指都与拇指共线或高于拇指，导致抬离后更大的滚动，特别是对于RHL组。研究结果表明，虽然把握控制的动力学是完整的，把握控制的运动学受损。这项研究增加了对USCP儿童预期规划和抓握控制的潜在机制的理解，并可能为如何改善USCP儿童的手功能提供见解。
Children with unilateral spastic cerebral palsy (USCP) have impairments in motor planning, impacting their ability to grasp objects. We examined the planning of digit position and force and the flexibility of the motor system in covarying these during object manipulation. Eleven children with a left hemisphere lesion (LHL), nine children with a right hemisphere lesion (RHL) and nine typically developing children (controls) participated in the study. Participants were instructed to use a precision grip with their dominant/less affected hand to lift and keep an object level, with either a left, centered or right center of mass (COM) location. Digit positions, forces, compensatory torque and object roll where measured. Although children with USCP generated a compensatory torque and modulated digit placement by lift-off, their index finger was either collinear or higher than the thumb, regardless of COM location, leading to larger rolls after lift-off especially for the RHL group. The findings suggest that while the kinetics of grasp control is intact, the kinematics of grasp control is impaired. This study adds to the understanding of the underlying mechanisms of anticipatory planning and control of grasp in children with USCP and may provide insights on how to improve hand function in children with USCP.
