目的：在基本功能方面有限的资源可能是功能活动的限制因素。本研究的目的是检查幼儿双侧痉挛性脑瘫（BSCP）的基本手部运动能力，并与功能活动缺陷进行比较。方法：88例BSCP患儿。3-6岁，操纵一个装有单轴力传感器的握力物体（200g）。基本运动能力是根据(1)最大握力和(2)快速重复握力变化（FFC）来评估的。受试者在这项任务中的表现与受试者在举起同一物体时评估的握力幅度和力率进行了比较。根据手工能力分类系统（MACS）对不同程度的手工能力进行比较。结果：在BSCP患儿中，即使在MACS为1的高功能患儿中，快速握力变化和握力均低于对照组平均值2个标准差以上。从MACS 2到4，差异增加，但在MACS 1和2之间没有差异。在举重过程中，患有BSCP的儿童使用了相当大比例的最大握力（40-90%）和70%对86%的握力。在一些手操作能力较低的儿童（MACS 3/4）中，起吊时握力率高于FFC时。结论：BSCP患儿的基本运动能力可能影响手操作能力，尤其是MACS 3和4级患儿。在这些儿童中，举重过程中的潜在过程也可能有质的不同。2008爱思唯尔爱尔兰有限公司版权所有。
Objective: Limited resources in terms of elementary functions may be a limiting factor for functional activities. The objective of the Study was to examine basic hand motor capacities in young children with bilateral spastic cerebral palsy (BSCP) and to compare with deficits in functional activities. Method: Eighty-eight children with BSCP. 3-6 years of age, manipulated a grip object (200 g) equipped with a uniaxial force sensor. Basic motor capacity was assessed based upon (1) maximal grip strength and (2) production of fast repetitive grip force changes (FFC) while holding the object on the table. Subjects' performance on this task was compared to the grip force amplitude and force rate assessed while the Subject was lifting the same object. Results were compared between different degrees of manual ability according to the Manual Ability Classification System (MACS). Results: In children with BSCP, even in high-functioning children with MACS 1, fast grip force changes and grip strength were 2 SDs and more below the mean of controls. Differences increased from MACS 2 to 4 but not between MACS 1 and 2. During lifting children with BSCP used considerable proportions of their maximum grip strength (40-90%) and of their grip force Fates during 70% vs. 86%. In some children with low manual abilities (MACS 3/4), grip force rates during lifting were higher than during FFC. Conclusion: In children with BSCP basic motor capacity may influence manual ability, particularly in children with MACS 3 and 4. In some of these children, the Underlying processes during lifting may also differ qualitatively. (c) 2008 Elsevier Ireland Ltd. All rights reserved.
